What is the difference between perception and cognition and role of nervous system both in perception and cognition?
Perception refers to the ability of the mind to apprehend objects through the sensory modalities of sight, hearing, smell touch and taste while cognition is the thinking about the perceptions in terms of individual previous experience. Hence cognitive process may entail the recall of previous experience or the evaluation of the objects perceived

Perception is mostly a priming memory role, while cognition includes some 33 major networks in the brain.
Perception is seeing a horse and saying in your mind " brown Arabian horse" while cognition "smells like, looks like, feels like, male? female? am I afraid of it? I love horses? I hate horses?". I hope this was helpful?
Perception involves more low-level subcoritcal systems, while cognition needs for high-level cortical networks.
Hi Atiq,
An interesting and important question! I think the answer depends on who you ask. The common assumption in contemporary psychology about perception is that perception/sensation is the first step in an encoding>processing>storage process. Perception within this approach is indirect; sensory experience is interpreted on the basis of past experience. The delineation between perception and cognition is, as the other contributors to this post have accurately suggested, a hierarchical delineation.
An alternative viewpoint that I'll toss into this conversation is Gibson's ecological approach, which starts with the assumption that perception is direct. That is, perception is the active process of detecting patterns within ambient energy arrays that specify the environment.
For example, the direction of self motion while locomoting is specified by the global optic flow that is generated from that movement. The origin of optical expansion unambiguously relates to heading direction. There is no need for further cognitive elaboration on this visual input, just the ability to detect it. Under the assumption of direct perception, the role of other cognitive functions in perception is unclear and perhaps unnecessary.
Unfortunately, theoretical development from ecological psychologists on other cognitive science topics is wanting. I just came across this paper, Neisser (1987), that seems to make contact with the relationship between perception and cognition. But, I cannot offer much more!
All the best,
Brandon
