Does anybody know of a fairly active neuroscience forum of decent quality?

Also, I have a question about EEG, if any neuroscientists or neurologists are present.

Question about the EEG?

'fraid I don't know any forums though...

[Anonymous No.1990361]

Can EEG readings be used to accurately assess cognitive function?

Referring specifically to intelligence and achievement test ability.

I've seen a somewhat dubious abstract in regards to this that showed moderate correlations, but I'm wanting further information from a more "up to date" source. Also, there is obvious advantages of human discourse in understanding information.

Not to be finicky, but could you hurry with your response?

I'm bordering a non-functional state of sleep deprivation.

I only have a clinical knowledge of them, nothing greatly in depth. But I would say no. The image is far too noisy with the little ones.

Even with the big thousand odd electrode ones get little beyond which areas of the brain are activating allowing you to access damage.

Intelligence? We're a long way from that, if you're referring to some kind of marker in the waves to show higher thinking. Though you could make certain assumptions, creativity, and auditory processing for instance with a decent enough EEG.

Hope that was at least slightly helpful.

Thank you.

I've been distraught over my poor EEG readings for awhile.

I've always frowned upon how fluid intelligence is assessed in psychometric tests, as it assumes intelligence is a single function that expands into areas of elarned cognition (mathematics, linguistics, etc).

I got my EEG, as I was having severe memory issues and to extract data as to whether or not I had ADHD. It gave me near-definite results of traumatic brain injury and a 70% of having a learning disability.

This was strange to me, as I've always done well on achievement tests and in academia with very minimal effort. generally aced tests whilst doing almost no homework.

The official administering the EEG seemed to believe I was severely impaired and generally had poor cognitive ability.

There's a 65% correlation with EEG predicting achievement tests and 68% with IQ.

Err, sorry.

I had thought that EEG would be a better predictor of fluid intelligence.

Also, I'm involved with a gifted program that selects based off achievement tests and loosely through teacher recommendation.

And despite all this, you really thought a test was going to prove you're borderline retarded?

[Anonymous No.1990574]

>>1990548

I've always had esteem issues I guess.

Sort of a self-defeating attitude.

But I am wondering, what do you think could be a possibility for such strange results? There is obviously an abnormality in my cognition.

EEG is very accurate in diagnosing brain damage and LD.

Brain damage? Seems like you likely have an unusually wired brain. Worth bearing in mind if you do have any other neurological exams.

You don't happen to be epileptic do you?

Wouldn't pick that up on an EEG, that's neurochemical imbalances. you're just being paranoid, but then again...that's a symptom of schizophenia!

Well, latent schizophrenia =/= schizophrenia.

It merely means I should probably avoid LSD. Unless I want to become an incredible artist or something.

Also, ADHD is signified by poor low beta activity and increased theta wave activity. Theta wave activity usually normalizes in those with adult ADHD, but the poor beta wave activity persists.

[Anonymous No.1990748]

>>1990713
I know, was just joking pal.

Why avoid LSD? It works on a totally separate pathway to dopamine.

Interesting about the ADHD though, makes sense.

Just came off the Arkham Horror FFG forums.
See Lovecraft.

Psychedelic drugs, particularly LSD, has been shown to alter the chemical systems of the brain, at least temporarily. This can often incite psychological breakdowns, insanity, and schizophrenia. This generally only occurs in those who are already at risk.

Not a neurologist in any respect, but doesn't this sound like a very simplistic way of looking at the brain and intelligence as a whole, which are both incredibly complex.
