Brodmann areas 35 and 36

Brodmann areas 35 and 36 are regions of the brain that are part of the Brodmann area classification system. This system was developed by the German anatomist Korbinian Brodmann, and is used to divide the cerebral cortex into 52 distinct regions. These areas are based on their cytoarchitectonic characteristics, or the organization and structure of their cells.

Brodmann area 35

Brodmann area 35, also known as the perirhinal cortex, is located in the medial temporal lobe of the brain. It is involved in various cognitive functions, including memory and perception. The perirhinal cortex is particularly important for object recognition and is involved in the process of familiarity detection.

Brodmann area 36

Brodmann area 36, also known as the ectorhinal cortex or the parahippocampal gyrus, is also located in the medial temporal lobe. It plays a crucial role in spatial memory and navigation. The parahippocampal gyrus is also involved in the encoding and recognition of environmental scenes.

Function

Both Brodmann areas 35 and 36 are part of the limbic system, a complex system of nerves and networks in the brain that controls basic emotions and drives. They are also part of the Papez circuit, a major circuit of the limbic system involved in the control of emotional expression.

Clinical significance

Damage to Brodmann areas 35 and 36 can result in various cognitive deficits, including amnesia and agnosia. These areas are also implicated in several neurological and psychiatric disorders, such as Alzheimer's disease, schizophrenia, and epilepsy.
