Question

What are brodmann areas and how do they relate to the neurological deficits that occur as the result of stroke?.

Answer 1

The Brodmann areas are a method of mapping the cortex and its distinct functions that was developed by Korbinian Brodmann, after whom the areas are named.

Korbinian Brodmann (November 17, 1868 – August 22, 1918) was a German neurologist best known for classifying the cerebral cortex into 52 distinct regions based on cytoarchitectonic (histological) characteristics. These areas are now commonly known as Brodmann areas.

The Brodmann classification divides the cortex into approximately 52 sequentially numbered areas, though some regions have since been subdivided and others are only found in non-human primates.

It is in charge of motor movements such as contralateral finger/hand/wrist or orofacial movements, learned motor sequences, breathing control, and voluntary blinking. The primary visual cortex (Brodmann area 17) is located on the medial surface of the occipital lobe, in and on either side of the calcarine sulcus.
