Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision. The temporal lobe processes memories, integrating them with sensations of taste, sound, sight and touch.

Brain Overview

The cerebrum is divided by a longitudinal fissure into 2 hemispheres, each containing 6 discrete lobes:. The limbic lobe limbic system is a C-shaped area on the most medial edge of each cerebral hemisphere; it includes some parts of the adjacent lobes. Although specific functions are attributed to each lobe, most activities require coordination of multiple areas in both hemispheres. For example, although the occipital lobe is essential to visual processing, parts of the parietal, temporal, and frontal lobes on both sides also process complex visual stimuli. Brain function is extensively lateralized.

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. This is why in frontotemporal dementia , personality changes are often the first signs of the disease. 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.

Brain Overview

The lobes of the brain were originally a purely anatomical classification, but have been shown also to be related to different brain functions. The cerebrum , the largest portion of the human brain , is divided into lobes, but so is the cerebellum. If not specified, the expression "lobes of the brain" refers to the cerebrum. Terminologia Anatomica and Terminologia Neuroanatomica divides the cerebrum into 6 lobes. The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.

Lobes of the brain

The brain is an amazing three-pound organ that controls all functions of the body, interprets information from the outside world, and embodies the essence of the mind and soul. Intelligence, creativity, emotion, and memory are a few of the many things governed by the brain. Protected within the skull, the brain is composed of the cerebrum, cerebellum, and brainstem. The brain receives information through our five senses: sight, smell, touch, taste, and hearing - often many at one time.

The Frontal Lobes are located in the front of the brain. They are very large and have many functions. The frontal lobes are considered to be our emotional control centre.
