Piriform cortex
Piriform Cortex
The Piriform Cortex (pronounced: pie-ri-form kor-teks) is a region of the brain that is part of the olfactory system. It is involved in the processing of olfactory information, or the sense of smell.
Etymology
The term "Piriform Cortex" is derived from the Latin word "pirum" meaning pear, and the Greek word "kortex" meaning bark or shell. This is due to the pear-like shape of this region in the brain.
Function
The Piriform Cortex is primarily responsible for the processing and perception of olfactory (smell) information. It receives direct input from the olfactory bulb, which is the first region of the brain to receive olfactory information from the nose. The Piriform Cortex then processes this information and sends it to other areas of the brain, such as the orbitofrontal cortex, for further processing and integration into conscious perception of smells.
