Thanks.

No I am not a neurobiologist but I have MD and PhD in biomedical sciences so I know few things about how human brain works.

In anyway I tried may be 2 or 3 years ago to find what you are asking me but there was no such research published in the scientific research magazines (including payed subscription one). So it must be private. In anyway I am sure you can extract the same information by already published data but you must read a number of theoretical neuroscience research articles and extrapolate the knowledge from there. Unfortunatly I have no time for this right now (finishing a 10 years old project by the end of the year). But if one day I get more specific insights I promise to share them with the community!
