Hunch almost clinched.
Grid cells like to fire at angles, and there are effectively multiple overlapping hexadirectional grids where the angles are preserved but the sizes of the grids are different.
It won a couple of scientists a giant prize in 2014.
I have a hunch that the angular firing leads to a sense of infinity via its interpretation as distance perspective. (vanishing point)
Most of the other senses seem to have a more temporal awareness quality to them.
Auditory and kinesthetic, smell and taste, have rise and fall which is time.
Vision is Ongoing change with an illusion of unchanging allowing such things as a sense of “background / foreground”
I have to think through this further more later and see if this was touched upon by somebody else in a paper somewhere. Must’ve been.
