Brodmann area 47
Brodmann area 47 is one of the cytoarchitectonic regions of the brain as defined by Korbinian Brodmann. It is located in the frontal lobe, specifically in the ventrolateral prefrontal cortex. This area is also known as the orbital part of the inferior frontal gyrus and is involved in various cognitive functions including language, thought, and decision-making processes.
Anatomy[edit | edit source]
Brodmann area 47 is located in the frontal cortex, in the ventrolateral prefrontal cortex. It is part of the inferior frontal gyrus, which is divided into three parts: the pars opercularis, pars triangularis, and pars orbitalis. Brodmann area 47 corresponds to the pars orbitalis.
Function[edit | edit source]
Brodmann area 47 plays a significant role in various cognitive functions. It is involved in language processing, particularly in semantic tasks. It is also associated with decision-making processes, especially those involving reward and punishment. Additionally, this area is implicated in thought processes, including reasoning and social cognition.
Clinical significance[edit | edit source]
Alterations in Brodmann area 47 have been associated with various neurological and psychiatric conditions. For instance, it has been implicated in schizophrenia, autism, and attention deficit hyperactivity disorder (ADHD). Moreover, damage to this area can result in aphasia, a language disorder that affects a person's ability to communicate.
