How are object represented neurally?

No one knows.

Lesion studies say otherwise.
Michael Turner
lesions don't explain everything

Easton Wright
the ventral visual pathway represents object names/meaning
the dorsal visual pathway represents the object in visual space
ventral pathway is conscious
dorsal pathway is unconscious
example for damage to ventral pathway, see blindsight (en.wikipedia.org
for examples of the other type (inability to manipulate objects) here: ncbi.nlm.nih.gov
also there is a special spot in the right hemisphere called the fusiform gyrus that is specifically evolved to recognize faces (en.wikipedia.org
any other questions?
there's still a lot that's unknown btw
t. studied neurobiology in undergrad

What do you mean by that? Pretty sure I'm also conscious of visual stuff going on.

so look around the room and notice all the objects
in your mind you can name the objects, describe what they are, and what they look like
this is all conscious information that you can name from your declarative memory
then there is a 2nd "type" of information about the objects
that is there size, shape, and procedural knowledge of how to manipulate the objects in space (see pic related)
the ability of your brain to do this is largely unconscious (i.e. there are people who can do pic related just fine but when asked what orientation the letter slot is in they have no idea)
pretty interdasting stuff
