There are two different neural correlates of perception, the stream which provides "what" information (perception) and the stream, which provides "where" information (action input)

ventral dorsal

Explanation:

The perception and processing of visual information is divided into two streams that travel through different pathways in the brain after the primary visual cortices.The ventral stream runs to the inferotemporal cortex, whereas the dorsal stream to the posterior parietal cortex.The ventral stream identifies the object, whereas the dorsal stream detects where the object is i.e. spatial information.According to research, the ventral stream is involved in the perception of information about objects (vision for perception).The dorsal stream processes information to guide actions (vision for action).
