Sir Charles Scott Sherrington is one of my science heroes, so I'm featuring him on my cogsci profile. He is often credited with coining the word "synapse."

comment Can microdialysis be made in Drosophila melanogaster?
@NickStauner I disagree, this is a common method in neuroscience.

A tinfoil hat will alleviate this problem.

comment What is a good rough rule of thumb regarding required sample size for questionnaire studies?
At its heart this is a good question. It's tough to answer without knowing what your metric for "meaningful" is. A starting point would be Cohen's d, but I don't know how accepted that is in the survey community.

comment Who was the man who invented language?
This doesn't seem to be asked in earnest. There is a ton of background information out there about linguistics, I'd recommend starting there and asking a question about that instead.

comment Why do we have urge to eat when we are not even hungry
I agree, this needs some elaboration. Do you mean compulsive overeating or something of that nature?

comment Why can't we use 100% of the brain in a certain moment?
In a grossly oversimplified sense, disorders like schizophrenia and mania are a result of "overactivity" of certain transmitter systems, so "more is better" is just as faulty an argument within neuroscience as it is in political science.

the point is that we do not use more than a 10% in any moment That's not really true, either. theatlantic.com/technology/archive/2014/07/…

comment Can one become less neurotic?
It depends on how you measure "neurotic", really.

comment Can a person control their brain's electrical activity?
The P300 response will not be as pronounced, but won't be completely eliminated in the case of "if the user knows that stimulus..." that you cite in the comment. Remember that we analyze these EEG patterns over multiple epochs (short periods of time) and can time-lock them to the stimulus, so we can "line up" the responses and average them.

comment Can a person control their brain's electrical activity?
@Learner It's laid out in the Wikipedia article, but if you have an auditory stimulus that's going "beep, beep, beep, beep", and every few seconds there is a "boop" mixed in, the "boop" is a low-probability stimulus (less likely to occur) and will generate a more pronounced P300 wave. This phenomenon can occur naturally as well if we are surprised by something (a siren on a quiet day, etc.). I don't quite know how such an effect manifests for a visual stimulus, but I imagine that the "oddball" effect is somewhat similar.

comment How do ligands bind to and release from receptors?
This is the text used in the course. It's gone up a lot in price, but it's very helpful.

comment How do ligands bind to and release from receptors?
Look for the Coursera course "Drugs and the Brain" and see when it's offered next. It touches on a lot of these issues and more, and I think you would find it fascinating. Meanwhile, I'll see if I can answer some of this a bit later.

comment What does Inter-Personal conflict means in clinical evaluation?
Is this a real instance of a clinical evaluation? No one really uses Rorschach tests anymore, especially not for diagnosing depression in the clinic.

comment How do laypeople form a judgement that another person is smart or intelligent?
It's a lot better. :) I think you should refocus it on how we define thresholds for subjective measurements, as that would provide a more general answer, but it's up to you.

comment What causes people to rapidly lose skill after becoming moderately good at something?
Self-help questions are discouraged on the site. This question was only marginally in that category, but I have edited out the personal aspects to make it more general and to discourage voting to close. Feel free to make any changes to my edits as needed.

comment How do laypeople form a judgement that another person is smart or intelligent?
The second part of this question makes it off-topic. The first part is marginally on-topic, but as you've figured out for yourself, these definitions are highly subjective. I'd recommend reformulating a question around that.

Sorry to be "Johnny Comment" here, but this related Bio.SE question has some good information: biology.stackexchange.com/questions/19767/…
