frontal lobe structure and function

The frontal cortex, or frontal lobe, is among different regions that together comprise the cerebral cortex, the outer layer of the brain. The frontal lobe extends from the most anterior part of the brain to the Fissure of Roland (Or central fissure) where it begins The parietal lobe And, on the sides, to the fissure of Silvio (or lateral fissure) that separates the temporal lobe. The anterior (front) portion of the frontal lobe is called the prefrontal cortex.It is very important for the "higher cognitive functions" and the determination … function Here are some of the most common symptoms of frontal lobe stroke:Hemiparesis or hemiplegia.

Frontal lobe The frontal lobe is a part of the brain that controls key functions relating to consciousness and communication, memory, attention, and other roles. Frontal Lobe This lobe is located at the front of the brain and is associated with reasoning, motor skills, higher level cognition, and expressive language. The temporal lobe sits beneath the temporal bone of the calvaria, inferior to the frontal and parietal lobes, from which it is separated by the lateral sulcus. There are four lobes that make up the brain. It is also where the primary motor cortex, the area of the brain responsible for controlling voluntary movement, is located. The frontal lobe is involved with the main executive functions of the brain, which include: Judgment, that is, the ability to recognize future consequences resulting from ongoing actions. The human brain is a very complex structure; it is the center of our nervous system. Assessing future consequences of current actions.
