comment Does transparency have its own visual channel?
'low-level processing' is not a well defined term. Do you mean in V1 (primary visual cortex)? I think transparency is a higher-order feature that requires (object) boundary detection. I doubt you can see a big effect of it in the early visual processing where color and orientation are processed.

comment What is the estimated cost of validating a psychometric test?
what's "io" and "ie"? I'd edit your english, but I'm not sure what you mean.

comment What kinds of information can (and cannot) be extracted from connectome?
Ideally connectome will contain the information 1,2,3. However, depending on the technique (e.g. electron microscopy on slices) it may not get them. I think it would be more clear if you dissociate the technique from the goal of connectomics itself.

@NewAlexandria You are right. Perhaps my reaction was too harsh...

Surprised that nobody mentioned Hopfield network.

comment What delay between two audio sources is seen as “noticeable” to most people?
probably in the order of microseconds...exactly because of source localization.

how are you defining "accuracy"?

comment References for biologically plausible models of knowledge representation?
I must say the VSA (vector symbolic architecture) and it's neural implementation doesn't strike me as being biologically plausible. I guess it is relatively more plausible than what the authors are comparing to in some sense.

Some parts of your post is very fishy and highly likely pseudoscience. That omega432.com is full of nonsense.

comment Can our brain do trigonometry?
Motion can be represented without the 2D coordinate system that you are used to mathematically. For example, one can imagine having an adaptive dynamical system can learn such associations and emulate motion of objects in 2D with a 2D sheet of neurons.

@JakeWestfall thanks for your suggestion. I added a bit of details and made it community wiki. Feel free to edit it.

@WaqarAhmad I do not see anything wrong with my answer. I have updated it to include a robot example.

comment Are we to a point in research that we can correlate measurable phenomena with brain changes?
The question is improved. Yes, there are numerous animal studies that show stimulus induced plasticity often with changes in behavior. The question is still broad for me to answer specifically, though. IMHO, neuroscience have not yet achieved understanding at the level applicable to complex cognitive and personality level. Most of these tasks are very elementary perceptual/decision-making related, and I wouldn't draw any conclusions from them for therapy.

What do you mean exactly by the "efficacy of LTP"? Also, why are you only focusing on potentiation and not depression (in general plasticity)? Are you planning to specifically measure LTP? In early sensory areas where you can reliably evoke action potentials with stimuli perhaps it is possible to say it is causal, but in higher order areas causal relationships of this sort is not clear. LTP in which area on what kind of task are you talking about? All LTPs in the brain??? (also there's a typo in the title)

You mean electrophysiologically? Can you clarify?
