comment How fast is the visual system?
Although, now that I think about it, the MLR wouldn't be coming from A1, even though it would be measured on the scalp.

comment How fast is the visual system?
"the potential over V1 is more like 100 ms after stimulus." Wait, what? I get a peak of activity over V1 after about 100 ms in my MEG study. I've also seen reports of A1 effects at 15 ms or less after tone onset (early MLR response).

comment Can dreams be memorised?
I think this can be easily answered. I will find my course notes one of these days to give the details, but it is known that some neurotransmitter necessary for translating short-term into long-term menory is inactive during sleep.

comment How does the brain read rotated text?
This is a very nice answer. I'd like to add that we probably first need to learn that the orientation of a letter matters in the first place (i.e. it can be a different letter if seen from a different orientation, like p and d). With all other objects, their identity remains the same no matter from what angle we see them from.

comment Which are the most accredited tests for measuring personality traits?
I think this is an OK question! I even had a similar exam question as a student for my personality psychology course: "Why big 5 instead of big 3 or small 16?" (i.e. Costa&McCrae vs. Eysenck vs. Spearman).

comment Why do long range axons in mammals travel in white matter tracts?
Very interesting indeed! Let me speculate: a lot of neighbouring neurons from one area will need to connect to neighbouring neurons in the next area in a processing stream. If they all follow the shortest path, they will end up in a bundle.

comment Are “dumb product warning labels” an indicator of change of intelligence of general public?
To claim that IQ might be dropping because of something, you first have to ascertain that it is in fact dropping. But, as you already say, according to research, it's rising. So, no, it's not dropping because of the labels, because it's not dropping.

comment Innate personality tests: do they exist? If not, why?
That's definitely true. But if you want to examine personality, you have to start from looking at how people behave, or feel, or think, and these are already influenced by a combination of genes and environment. Scientists are looking for genes as well, but it seems that personality traits are the outcome of many mutually interacting genes, rather than just a few, like eyes. So in the end it's hard to say anything about any of the individual genes present in this massive interaction.
