Located in the premotor cortex. They are highly specialized to respond to specific stimuli. If a similar stimuli is encountered again the same neuron is activated.

Mirror neurons

Our knowledge of concepts comes from the reactivation of neurons when we interact with them again.

Hypotheses about knowledge of categories and concepts in the brain

The major method of consolidation. The process where the hippocampus replays events associated with a memory.

Cognitive psychology: Connecting mind, research and everyday experience

There are specific neural circuits in the brain for certain categories. These neural circuits are innately determined based on how they helped survival.

Semantic category approach 

Living things are identified using sensory objects and artifacts by functions. This leads to the conclusion that our ability to differentiate artifacts and living things comes from our semantic memory (which has a system for distinguishing sensory attributes and another for functions).

Sensory-functional (S-F) hypothesis

Categories have a distributed representation which take into account many features which determine how concepts are divided up within them.

Multiple factor approach

Many animals share similar features (i.e. legs, eyes, etc). Artifacts on the other hand do not share as many (they are more variable. This has led researchers to the posit that the reason some people have trouble identifying different animal related categories is because they share many features.
