How many frontal lobes




















Traditionally, each of the hemispheres has been divided into four lobes: frontal, parietal, temporal and occipital. Although we now know that most brain functions rely on many different regions across the entire brain working in conjunction, it is still true that each lobe carries out the bulk of certain functions.

In humans, the lobes of the brain are divided by a number of bumps and grooves. These are known as gyri bumps and sulci groves or fissures.

The folding of the brain, and the resulting gyri and sulci, increases its surface area and enables more cerebral cortex matter to fit inside the skull. The frontal lobe is separated from the parietal lobe by a space called the central sulcus , and from the temporal lobe by the lateral sulcus. The frontal lobe is generally where higher executive functions including emotional regulation, planning, reasoning and problem solving occur.

This is why in frontotemporal dementia , personality changes are often the first signs of the disease. The most famous case of frontal lobe dysfunction is the story of railway worker Phineas Gage.

In , Gage was using a tamping iron to pack in gunpowder for blasting a tunnel through rock. While his head was slightly turned, a mistaken strike sparked an explosion that forced the rod upwards into his left eye and out through his skull. Recovering from a frontal lobe injury is often a long process. Progress can come suddenly or infrequently and is impossible to fully predict.

Recovery is closely tied to supportive care, regular cognitive challenges, and a lifestyle that supports good health.

Frontal Lobe: Function, Location and Structure The frontal lobe is the home of much of what makes us human. Author: Spinalcord. Where is the Frontal Lobe Located? What Does the Frontal Lobe Do? Some of the many functions of the frontal lobe include: Coordinating voluntary movements, such as walking and reaching for objects.

The frontal lobe is home to the primary motor cortex. Assessing future consequences of current actions. Thus the frontal lobe plays a vital role in impulse control, including decisions about when to spend money and eat, and whether a particular decision is morally or socially acceptable.

Assessing similarities and differences between two objects. Formation and retention of long-term memories, particularly emotional memories derived from the limbic system.

Language: The frontal lobe plays a role in understanding language, linguistic memories, and speaking. Emotional expression and regulation, in addition to understanding the emotions of others; empathy may derive from the frontal lobe.

The development of personality. Because of the frontal lobe's roles in memory, emotional regulation, expression, impulse control, and other key functions, it plays a key role in personality. Damage to the frontal lobe can spur sudden and immediate alterations in personality. Managing reward. Dopamine, a neurotransmitter that plays a role in reward and motivation, is heavily active in the frontal lobe because most of the brain's dopamine-sensitive neurons located here.

Attention regulation, including selective attention. Frontal lobe difficulties can lead to executive functioning issues, as well as disorders such as ADHD. Those include: Medial frontal lobe: This region contains the cingulate gyrus, which is a part of the limbic system.

It also contains the superior frontal gyrus, which research suggests plays a role in self-awareness. Lateral frontal lobe: This region contains the superior frontal gyrus, which aids in self-awareness, as well as the middle frontal and inferior frontal gyrus.

The inferior frontal gyrus plays a role in language processing. Anatomic Moment. The Septal Area. PMC - Pubmed 7. Neil M. Borden, MD, Scott E.
