Cortical lobule

Cortical lobule is a term used in anatomy to describe a part of the brain's cerebral cortex. The cerebral cortex is the outermost layer of the brain, and it is divided into several different lobules, each of which has a specific function.

Etymology[edit | edit source]

The term "cortical lobule" comes from the Latin cortex, meaning "bark", and lobulus, meaning "a small lobe". This reflects the fact that the cortical lobules are small sections of the larger cerebral cortex.

Structure and Function[edit | edit source]

Each cortical lobule is made up of several gyri, or ridges, and sulci, or grooves. These structures increase the surface area of the brain, allowing for a greater number of neurons and thus a higher level of brain function.

Different cortical lobules are associated with different functions. For example, the frontal lobe is associated with higher cognitive functions such as decision making and planning, while the temporal lobe is associated with auditory processing and memory.
