Objects seen as scenes: neural circuitry for attending whole or parts
[article]
2019
bioRxiv
pre-print
Preserved Fulltext
We hypothesize that object hierarchical level is processed by neural circuitry that also analyses spatial layout in scenes, contributing to the control of the spatial-scale used for shape recognition. ...
AbstractDepending on our goals, we pay attention to the global shape of an object or to the local shape of its parts, since it's difficult to do both at once. ...

The neuronal recording studies show that individual neurons can be highly tuned in that they convey information about face identity, or about face expression, or about objects, or about spatial view. ...

We refer to these mechanisms as "attention." Attention acts by increasing the strength of selected neural representations and preferentially routing them through the brain's large-scale network. ...
Attending to a spatial location will select an object (or a piece of an object) at that location. ...
In daily life, we select meaningful objects from meaningful scenes such as looking for cars when crossing a street. ...
