Dictionary definition of cortical

Referring to the outer layer of an organ, particularly the brain.
"The cortical regions of the brain are responsible for processing sensory information."

Detailed meaning of cortical

The brain's cortex, also known as the cerebral cortex, is the outermost layer of the brain and is responsible for a wide range of functions, including sensation, perception, memory, and consciousness. The cortex is divided into several regions, each of which is responsible for specific functions. For example, the motor cortex is responsible for controlling movement, while the visual cortex is responsible for processing visual information. Cortical disorders can affect various aspects of brain function, leading to symptoms such as sensory deficits, language impairments, and memory problems.

Example sentences containing cortical

1. The neurosurgeon carefully avoided damaging the cortical tissue during the operation.
2. Studies have shown that cortical thinning is a common feature of aging brains.
3. The cortical surface of the brain is highly convoluted to increase its surface area.
4. The EEG measures the electrical activity of the cortical surface of the brain.
5. The cortical areas of the brain responsible for language are typically located in the left hemisphere.
6. Patients with Alzheimer's disease often exhibit cortical atrophy in certain regions of the brain.

History and etymology of cortical

The adjective 'cortical' derives its etymological roots from the Latin word 'cortex,' which means 'bark' or 'rind.' In the context of anatomy and biology, 'cortex' specifically refers to the outer layer or surface of an organ. When applied to the brain, 'cortical' pertains to the outer layer of neural tissue that plays a crucial role in higher cognitive functions and information processing. This etymology eloquently conveys the essence of 'cortical' as something related to the outer layer of an organ, highlighting its association with the brain's outermost layer, where complex mental processes occur. The term 'cortical' underscores the significance of this brain region in understanding and exploring the complexities of human cognition and neurology.
