  • Welcome to 2 minute neuroscience, where I simplistically explain neuroscience topics

  • in 2 minutes or less.

  • In this installment I will discuss the lobes of the brain and some major landmarks of the

  • brain surface that can be seen from a lateral view.

  • The brain is made up of two halves, known as cerebral hemispheres.

  • When looking at the brain from a lateral view, which just means looking at it from the side,

  • we will only see one cerebral hemisphere, but the landmarks I will point out are found

  • on both cerebral hemispheres.

  • The surface of the cerebral hemispheres is covered with a thick layer of brain tissue

  • known as the cerebral cortex.

  • The cerebral cortex is folded to create more surface area, forming these ridges known as

  • gyri and grooves known as sulci.

  • This large sulcus is known as the central sulcus.

  • It divides the frontal lobe from the parietal lobe.

  • This sulcus is known as the Sylvian fissure, and it separates the temporal lobe from the

  • rest of the cerebral hemisphere.

  • The occipital lobe is found at the back of the brain, but it doesn’t have such a clear

  • division separating it from the rest of the brain.

  • There are certain functions associated with the lobes, but any short description of these

  • functions is oversimplified, as each is involved in many different processes.

  • The frontal lobes are important for movement and higher-order cognition like rational thought,

  • decision-making, and planning.

  • This area in front of the central sulcus is known as the precentral gyrus, and it is essential

  • for motor control as it is the location of the primary motor cortex.

  • The parietal lobes are important for processing of sensory information and are involved in

  • attention and our representation of the space around us.

  • This area in the parietal lobe, the postcentral gyrus, contains the primary somatosensory

  • cortex and is where the sense of touch is processed.

  • The temporal lobe is involved in processing auditory signals and also is important in

  • aspects of learning and memory.

  • The occipital lobes contain major visual processing areas of the brain, like the primary visual

  • cortex.
