Although I was really fascinated by the lectures about perception/vision last week, I was most intrigued by the statements on evolution of perception.

In particular, I was intrigued by the lateral inhibition network of perception that stated that what we perceive (by sensory neurons) is quite different than the unconscious construction our brain puts forth to understand the inputs.  When in development does this filtering and construction by the brain develop?  How does this relate to perception development in similar organisms?

Also, it seems that with this notion of brain evolution, one tends to think of the human brain as the most advanced/complex.  Although evidence from the neocortex would suggest this (see my first paper), perhaps perception does not?  Could it be that other 'less complex' organisms in fact have more complex perception systems?  How should we evaluate which species has the most advanced/complex visual/perception system?
