Ehud Ahissar and PCT

Dear Warren,

Hi
J

yes, I’m a great admirer of Powers and his PCT. Someone mentioned PCT to me years ago, following one of my closed-loop oriented publications - I have read it
with enormous pleasure and since then every student entering my lab is oriented to his book or ‘73 paper…

My current paper, in addition to presenting a closed-loop hypothesis for perception (which is different than PCT but not unrelated), is also a kind of a call
for getting the closed-loop framework back to the front stage of neuroscience – but as you know, it is hard to shift the neuroscience wagon ffrom its track…

Will be happy to chat if we have a chance

Best, ehud

Dear Ehud,

I have seen your recent citation of Powers and taken a look at your publications. I would be interested in a pdf copy of the recent published article below.

I don’t know if you know but the particular implications of closed loop neuroscience - ‘behaviour as the control of perception’ - are the central tenet of Powers’ theory, and since 1973 the theory has been tested and utilises in many ways
that challenge the traditional S-R open loop approach. I manage a website
www.pctweb.org
that links to the studies.

In particular there are neuroscience labs specialising in Powers’ closed loop model at Duke (Henry Yin), Lethbridge (Sergio Pellis) and Alicante (Alex Gomez-Marin).

I hope these resources interest you and I look forward to hearing from you,

Warren
