Thanks Chandan.
“The first time I saw that work I nearly fell out of my chair -- it is
so amazing,” she said. “It is the beginning of how memory is
represented. This is why some people compare memories to moving through
space.”
... which is why i believe a foundation in movement is key to
understanding the nervous system and building AGI, and why i believe the
sensory-motor work in NuPIC is the most important area of the project
right now.

Many of us may have read this by now. It would be interesting to see
how this fits into the concepts at work in future development within
Nupic .

/"He found that when he placed rats in certain parts of a room
different cells in the brain’s hippocampus – which is believed to be
important in functions related to space and memory -- were always
activated. He theorized that these areas that he called “place cells”
formed a map of the room."

/"A *place cell* is a type of pyramidal
<http://en.wikipedia.org/wiki/Pyramidal_cell> neuron
<http://en.wikipedia.org/wiki/Neuron> within the hippocampus
<http://en.wikipedia.org/wiki/Hippocampus> that becomes active when
the animal enters a particular place in the environment; this place is
known as the place field. A given place cell will have only one, or a
few, place fields in a typical small laboratory environment, but more
in a larger region.^[1]
<http://en.wikipedia.org/wiki/Place_cell#cite_note-1> There is no
apparent topography to the pattern of place fields, unlike other brain
areas such as visual cortex - neighbouring place cells are as likely
to have distant fields as neighbouring ones.^[2]
<http://en.wikipedia.org/wiki/Place_cell#cite_note-2> In a different
environment, typically about half the place cells will still have
place fields, but these will be in new places unrelated to their
former
locations./^/"/<http://en.wikipedia.org/wiki/Place_cell#cite_note-3>
