Welcome. This forum was initially created by Numenta and is moderated by Matthew Taylor, a Numenta employee. Numenta's goal is to reverse engineer the neocortex.That is, by definition, a very detailed biological endeavor. We want to understand how the neocortex works at a level of detail that is testable by experimental neuroscientists, and also at a level of detail sufficient to create SW and HW technologies that work on the same principles as the neocortex. It is our belief that to create truly intelligent machines we first need to understand what the brain does and how it works.
Psychology and neuroscience are ultimately concerned with similar things such as thought and mental states, but differ greatly in their approach. HTM theory is a theory of how the neocortex works, which means how the detailed biology works. At Numenta we review the literature on EEG and fMRI, but we view anatomy and physiology as more instructive to our goals.
I imagine there are probably other forums that focus on cognitive psychology.
