What is cognitive neuroscience?

In short, cognitive neuroscience is the biological study of human information processing! This includes brain mapping (f/MRI, DTI, M/EEG), computational neuroscience, psychology, and philosophy of mind. We make pretty pictures of your brain in action, and then try to interpret them using the language of psychology and information theory!

Definition from wikipedia:

Cognitive neuroscience is an academic field concerned with the scientific study of biological substrates underlying cognition, with a specific focus on the neural substrates of mental processes. It addresses the questions of how psychological/cognitive functions are produced by the brain. Cognitive neuroscience is a branch of both psychology and neuroscience, overlapping with disciplines such as physiological psychology, cognitive psychology and neuropsychology. Cognitive neuroscience relies upon theories in cognitive science coupled with evidence from neuropsychology, and computational modeling.

What if brain death isn’t as final as we’ve come to believe?

As passionate 9th graders (freshmen), we feel an urgency to question this assumption, wondering if lives are being prematurely written off that could potentially be saved.

Driven by this vision, the three of us are exploring innovative solutions, and we’re incredibly grateful for your guidance.

We'll be presenting our solution in an Ivy League competition with a February 1, 2025 deadline, and would love your feedback and support.

Our Proposal:LCN2, a protein linked to inflammation and scarring after brain injury, limits regeneration in humans. Zebrafish, however, can regenerate brain tissue by transforming glial cells into neurons. Inspired by this, our idea is to target LCN2 with antibodies to reduce scarring and allow more brain regeneration to occur. After reducing LCN2’s effects, we also propose using induced pluripotent stem cells (iPSCs) to increase the number of neurons in the injured area. These iPSCs can be guided to become neurons, helping to restore lost brain cells and potentially improving recovery for brain injury patients.

We recognize this idea is ambitious and may have its limitations. We would be immensely grateful for any guidance you can offer to steer us in the right direction—or suggest alternative approaches that might bring us closer to our goal.

Consciousness The Ability To Form A Point Of View

Hello,

I am writing a book called Decoding Ourselves - "how I look at walls"

It is to reorient people the fact we are actually human beings and not human machines - you got to ask "If your brain is doing all you thinking what are you doing?"

I have used etymology, language structure and basic science to create 3 word formula that summates how we form a POV - here I'm just detailing an observation of the error in observation that stops one understanding consciousness.

Here is the definition from consciousness 1603 - "known to one self"

What is one self? Well there is only "one" "self" and the self can be defined as the "determiner without precedent." This means that all you determine to be starts and stops with you. The whole light show you are looking at right now is what you are creating and perceiving. All the data gathers to you.

What does know mean? Means to observe, make a prediction and execute. It really is scientific method being applied in life. It is done by continually forming points of view: Predicted View = Executed View.

Consciousness: Could be simply defined as the ability to form a Point of View. Fundamental to that is the Observer. Without the observer there is no point of view possible. That is the problem with materialism, it holds a view there is no "being or observer." If there was no observer there would be no materialism. So the view does not align with what they do - they say "no observer" while making an observation. Then to have science which involves observation based on the view "there is no observer - makes no sense.

The following is some really important observations. Truth comes from "deru" meaning steadfast. It is that which has to be before all else is possible and cannot be err eased or ignored If you bypass or ignore a truth, you have made an error and will wander around in circles. As you plough on you will get more complex, which is to twist and turn, eventually you will end up in mystery which comes from "to close your eyes." The word discovery is to take the covers off and if your view is wrong, keep researching a flawed view you are only validating the mystery. Then if the truth does come along it can be difficult to accept it as you are so invested in the mystery.

Here is how we bypass a truth and in doing so, turn a common sense, natural and fundamental ability, consciousness or the ability to form a PV, into an utter mystery.

So we take the sentence: "I look at walls." It is simple, common sense we all do that - it's a no brainer.

Here is how e generate mystery - we just take "I" the observer out of the sentence. So we end up with "looking at walls." Now we have gone from common sense to nonsense. We have bypassed the truth - kicked out "I" and replaced the observer with the machine.

Now we have to come up with theories explaining how the wall is looking and get ourselves stuck in a mystery.

When "I" the symbol of the steadfast observer was taken out it was a serious blunder. Nobody bothered to look that symbol is there any time a human being expresses a point of view. That it is always there regardless of the view. Materialist, spiritualist - it does not matter. That "I" is the observer or life source that is forming points of view. That is where the truth has been bypassed and why the ability to form a point of view is a mystery.

Everyone uses I. When someone asks you "What do you do?" and you reply "I am" - that is you the observer or being saying "I" am actually here observing and forming points of view, That is what you do all day every day and that is the process. You standing and processing forming views and being aware, applying scientific method, executing and experiencing life.

The word oblivion derives from "to forget, in my view " a materialist, is simply a being that has forgotten he is observing. He will use the language of the "observer" I am, I , my etc - but because he's forgotten he is observing, he thinks his mind is emerging from the brain, when it his mind, his faculty that he uses to form views of the world where is operating. Thus when he tries to understand how it is possible to form a view, he assigns this to an energy field which causes himself no end of mystery.

Final note "life" in ancient times was viewed as that intelligent agency that structured energy into incredible forms. As science has developed we have seen that "life" is using code and engineering to gain determinism over the energy field. Amidst the chaos there is logic and we have the ability, above any other life forms to decode and understand the laws of this universe. We may have been defined as "beings that walk on earth" but technologies we use and have developed, shows we are truly self determined beings. We will not lie down we rise to the challenge and science is manifestation of our determinism. We are beings, observers, "I"'s - we are life's top decoders. It is interesting with AI, that there is fear amongst people that AI might develop a sense of "self" and that it may determine we are surplus to requirements. Our basic fear is that we would be denied a right "to be" - to exert our determinism in the world. That resonates because it is true, we are self determined beings, we should align ourselves with truth not try and erase ourselves as shown above. Consciousness is what we do naturally, we should just embrace what we are instead on trying to prove what we are not - that will pull us into mystery.

Anyway I hope you found that different view interesting - I am going to continue writing. If anyone wants to know about the formula let me know.

Cheers

Does anyone know where I can learn how to do N400 analysis?

I am wondering if anyone has a good reference or tutorial that they could provide on N400 analysis.

I have been tasked with doing this analysis for my lab and I have done the preprocessing and epoching of the data but still need to do the actual N400 analysis with these epochs. I haven't seen a good tutorial yet for what to do with these epochs.

Could anyone point me in the right direction for a good source to learn and follow along with?

Thanks in advance for any help.

Can someone explain for a person who is mentally disabled / handicapped what they’re perspective of time / reality is?

I just am looking at what current science says?

Also, I wanted to ask, is it possible for a parent who has a mentally disabled child to develop and teach them at a young age in which that childs brain develops and as a result in later life they become an independent and conscious person?

How likely is it for my work to be published/ taken seriously as an undergrad?

How likely am I to be taken seriously as an undergrad trying to publish a paper?

I am a second year comp sci major about to wrap up my first degree before heading down a path towards a neuroscience PhD (unsure what subfield yet).

I am doing research under a professor of psychology and a holder of a PhD in clinical psychology.

My research is exploring the connection between novelty and reward. I plan to use a predictive coding framework to study how reward anticipation affects interpretation of novelty.

I plan to use an oddball style task to measure baseline prediction errors, then I plan to inform participants that they will be repeating the task with the detrimental effect of losing the total amount of momentary gain they receive when performance is low (higher misidentification or incorrect stimulus identification results in lower money gained).

I have a hypothesis that stimulus reward value association governs how novelty is interpreted and I would like to see that there is a dynamic change in predictive coding when participants are informed of this, particularly a bias in priors or a bias towards novelty.

Within this paradigm, I plan to make a larger argument about novelty being highly dynamic and contextual, and contingent upon designation of the novel stimulus.

That, and an argument about reward being vastly over simplified.

I feel like novelty is contingent upon designation from top down influence from cortical structures and the locus coeruleus and possibly some other midbrain structures help coordinate learning given this designation.

https://www.cell.com/trends/neurosciences/fulltext/S0166-2236(23)00268-0

https://pubmed.ncbi.nlm.nih.gov/17764976/#:~:text=while%20promoting%20recollection-,Anticipation%20of%20novelty%20recruits%20reward%20system%20and%20hippocampus%20while,Neuroimage.

https://www.frontiersin.org/journals/neuroscience/articles/10.3389/fnins.2022.967969/full

I got the attention of a masters cog neuro student who has similar ideas and would like to collaborate, they will be working with intracranial electrodes to stimulate midbrain structures to study something similar.

They haven’t gotten back in touch with me and I don’t know if their PI will approve the collaboration.

If that falls through, how likely is it that I can publish my results as an undergrad with my name as primary author, and how likely is it that my arguments won’t be dismissed due to my lack of proper background? How about my lack of biomedical data to back my arguments?

I don’t plan to make specific arguments about neurophysiological mechanisms explaining my data, rather defining a need to explore certain aspects of cognitive processes more thoroughly based on my work and existing work.

If it turns out I’m onto something, I plan to try and do some relevant research during my undergrad neuroscience degree.

Are there differences in cognition between psychedelic users and non-users?

We are recruiting participants for a dissertation study on differences in cognition between psychedelics users and non-users being completed as part of a master's degree at University of Bristol. If you were to take part, you would be required to follow the link to the study that applies to you as there will be separate links for psychedelics users and non-users. There would be a participant information sheet as well as complete a consent form for you to read through. Following this, there would be a questionnaire to complete which will include questions about yourself and your use of psychedelics and other drugs. There would then be a series of tests to complete which measure aspects of brain functioning. In total, the study would take approximately 20 minutes to complete.

Please only participate if you are using a laptop as the experiment will not be able to be accessed on an iPhone or iPad. The experiment will not be able to be accessed using Safari so please use another browser.

The information gathered about you through the study would be kept anonymous and only individuals directly involved in analysing your data would have access to it. You would be free to withdraw your data at any point during the data collection phase without giving a reason. Due to the anonymous nature of the data, it will not be possible for you to withdraw your data following completion of the data collection phase. You are eligible to participate in this study if:

  • You are over 18 years of age.
  • Have a good understanding of the English language.
  • Have normal-to-corrected vision.
  • Have either used psychedelics at least 25 times, but not in the past 4 weeks, or have never used a psychedelic. Specifically, we are interested in use of classical psychedelics, which include psilocybin, ayahuasca, lysergic acid diethylamide (LSD), and dimethyltryptamine (DMT). We are not interested in use of substances that may have psychedelic effects but are not classic psychedelics, such as ketamine, nitrous oxide, MDMA, or cannabis.
  • Have never been diagnosed with a mental health condition by a psychiatrist, such as depression or anxiety.
  • Have never been diagnosed with a neurological condition. These are conditions which affect the brain, spinal cord, or nerves, such as a brain tumour, dementia, Parkinson’s Disease, or epilepsy.
  • Have never had a head injury.
  • Have never been diagnosed with a neurodevelopmental condition. These are disorders that involve differences in the development of the brain which influence how the brain functions, such as autism, intellectual disability, or ADHD.

Please follow the link below to participate in the study if you are a psychedelics user:

Type of study

Hi was wondering what are the some alternatives for studies in cognitive neuroscience which don’t use online studies (psychopy etc). Is there areas that focus purely on experimental studies that are in person or possibly just measuring physiological changes in response to stimuli.

I have had experience with PsycoPy and the Posner task n it was not my cup of tea

New Research

Hi everyone,

I am about to start a masters in cognitive neuroscience. I have an aim to publish (which I hear is unlikely for masters thesis). Nevertheless, I wanted to know is there any new research that is interesting and loads of rationale to develop on. Also, my key desires is to have clear and concise research over just something completely new and potentially misguided. Please let me know if they also any good areas which produce robust findings and methodology which would potentially help me to publish

Thanks in advance

How to use high-pass and low-pass filtering at the same time?

Hello! I see many studies indicating they used for instance 30 Hz. high-pass and 0.5 Hz. low-pass filter. But in that case, wouldn't it make the data disappear? Because, it allows frequencies over 30 Hz (and removes below 30 Hz) and at the same time it allows frequencies below 0.5 Hz (and removes above 0.5 Hz.). Simply, all data should be gone, what am I missing? Thanks in advance!

EEG and Muse marker timestamp discrepancy

I am working on a project, looking at the correlation between groove and brain entrainment but, I ran into an issue with my data analysis. There is a significant discrepancy between the timestamps in the EEG recorded by Muse and the marker timestamps. This is keeping me from doing any more analysis

Does anyone know how I should go about fixing this?

New software for conducting fMRI ROI analysis

I recently published an article in the Journal of Open Source Software, detailing software I created to run ROI analyses on fMRI data (the fMRI ROI Analysis Tool, or fRAT for short).

Any voxelwise map can be used with the software, however some examples of usage of the software include:

  1. Calculation and reporting of tSNR for the region being investigated.

  2. Summarising effect size or beta maps for the region being investigated, using atlas derived ROIs. This prevents circular analysis which can occur when using functionally derived ROIs to conduct power analyses.

  3. Using the statistical and visualisation tools of fRAT to compare different MRI parameters, with the aim of optimisation of these parameters for the specific region being investigated.

The software will continue to be extended in the future to add new functionality, such as adding to the scan editing utilities currently present (adding simulated noise or motion to scans). There are installation instructions in the documentation in case you are interested in using it.

The neuroscience of stress: How it affects you and your brain & what to do

Hi, I recently wrote an article about chronic stress and its effects on the brain. I would appreciate some feedback on it.

In the article, I discussed how chronic stress affects the brain's cognitive, emotional, and physical health by triggering inflammation in the body, which weakens the blood-brain barrier and leads to brain inflammation. This, in turn, can cause a decrease in motivation, mental agility, and shrinkage of the hippocampus and prefrontal cortex. I also provided some suggestions on how to rest your brain after undergoing heavy stress for some time.

Please feel free to give feedback and share your thoughts. Here is the link: https://www.theistanbulchronicle.com/post/the-neuroscience-of-stress-how-it-affects-you-and-your-brain-what-to-do
