What are the 4 lobes of the cerebral cortex and what is each responsible for?
Table of Contents
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.
What are the 5 lobes of the cerebral cortex?
Each cerebral hemisphere is divided into five lobes, four of which have the same name as the bone over them: the frontal lobe, the parietal lobe, the occipital lobe, and the temporal lobe. A fifth lobe, the insula or Island of Reil, lies deep within the lateral sulcus.

What are the 4 different lobes of the brain?
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.
What are the 3 main sulci of the cerebral cortex that divides it into the 4 lobes?
Each cerebral hemisphere divides into four separate lobes by a central sulcus, parieto-occipital sulcus, and lateral fissure.
What is the name for the optic radiations that run through the temporal lobe on the way to the striate cortex?
Meyer’s loop
Some of the optic radiation axons run out into the temporal lobe on their route to the striate cortex, an anomaly called Meyer’s loop (see Figure 12.7). Meyer’s loop carries information from the superior portion of the contralateral visual field.
Which part of the brain is the largest and is divided into 4 lobes?
The cerebrum
The cerebrum is divided into four lobes: frontal, parietal, occipital and temporal.
What are the lobes of the cerebral cortex?
Frontal Lobes: These lobes are positioned at the front-most region of the cerebral cortex. They are involved with movement, decision-making, problem-solving, and planning. Occipital Lobes: Located just below the parietal lobes, the occipital lobes are the main center for visual processing.
Where is the cortex located in the brain?
The cortex covers the outer portion (1.5mm to 5mm) of the cerebrum and cerebellum . The cerebral cortex is divided into four lobes. Each of these lobes is found in both the right and left hemispheres of the brain. The cortex encompasses about two-thirds of the brain mass and lies over and around most of the structures of the brain.
Where are the parietal lobes located in the brain?
Parietal Lobes:These lobes are positioned posteriorly to the frontal lobes and above the occipital lobes. They are involved in receiving and processing of sensory information. The somatosensory cortex is found within the parietal lobes and is essential for processing touch sensations.
What are the cell layers of the cerebral cortex?
The cell layers of the cerebral cortex, from superficial to deep, are: Plexiform or Molecular layer – which is a fibre layer with apical dendrites and non-specific afferents. External or Outer granular cell layer – which are interneurons for non-specific afferent input.
