Oct 30, 2023 · Originally defined and numbered into 52 regions by the German anatomist Korbinian Brodmann in the early 1900’s, the Brodmann areas of the cerebral cortex are defined by its cytoarchitecture (histological structure and cellular organization).

Korbinian Brodmann (1868-1918) was a German neurologist who published research on cortical cytoarchitectonics in many species, including humans. This publication contained what was believed to be the first map of the cerebral cortex based on variations in neural structure. Brodmann (1909) studied the cortex in detail, observing how its layers, tiss...

prefrontal association complex: A region of the brain located in the frontal lobe that is involved in planning actions and movement, as well as abstract thought. agraphia : An acquired neurological disorder causing a loss in the ability to communicate through writing.
Areas 9, 10, 11 are located in the prefrontal cortex, these areas play roles in planning, decision-making, and personality expression. Areas 44 and 45 are often referred to as Broca’s region, these areas in the frontal lobe are crucial for speech production and some aspects of language comprehension.

Nov 9, 2023 · The brain is part of the central nervous system (CNS) along with the spinal cord. There is also a peripheral nervous system (PNS) comprised of 31 pairs of spinal nerves that branch from the spinal cord and cranial nerves that branch from the brain.

Anterior association area Located in the prefrontal cortex. Links information from other association areas. Important in memory, planning, and higher-order concept formation. Three unimodal association areas are located adjacent to their respective primary sensory cortical areas as shown in the figure.
