What is the lateral sulcus responsible for?

The lateral sulcus (Sylvian fissure) is a very deep fold seen on the lateral surface of the hemisphere running in an anterior to posterior direction and serves to separate the temporal lobe from the frontal and parietal lobes.

What is Sylvian sulcus?

The lateral sulcus (also called Sylvian fissure or lateral fissure) is one of the most prominent features of the human brain. The lateral sulcus is a deep fissure in each hemisphere that separates the frontal and parietal lobes from the temporal lobe. The insular cortex lies deep within the lateral sulcus.

What is Sylvian fissure in medical terms?

Medical Definition of sylvian fissure : a deep fissure of the lateral aspect of each cerebral hemisphere that divides the temporal from the parietal and frontal lobes. — called also fissure of Sylvius, lateral fissure, lateral sulcus.

What is the function of the parieto-occipital sulcus?

For practical purposes, an imaginary line running laterally from the dorsal tip of the POS to the preoccipital notch is considered the effective boundary separating the occipital lobe from the parietal and temporal lobes.

Is lateral sulcus same as lateral fissure?

prominent sulcus that separates the frontal (and parietal) lobe from the temporal lobe. The lateral sulcus is also known as the lateral fissure or Sylvian fissure.

What is the difference between lateral sulcus and Sylvian fissure?

The Sylvian fissure, also known as the lateral sulcus or fissure, begins near the basal forebrain and extends to the lateral surface of the brain separating the frontal and parietal lobes superiorly from the temporal lobe inferiorly 3. The insula is located immediately deep to the Sylvian fissure.

What fissure separates the cerebrum and cerebellum?

transverse fissure
cerebral fissures parietal and occipital lobes; the transverse fissure, which divides the cerebrum from the cerebellum; and the longitudinal fissure, which divides the cerebrum into two hemispheres.

What are the three main fissures in the brain?

The main cerebral fissures are the lateral fissure, or fissure of Sylvius, between the frontal and temporal lobes; the central fissure, or fissure of Rolando, between the frontal and parietal lobes, which separates the chief motor and sensory regions of the brain; the calcarine fissure on the occipital lobe, which …
