Central sulcus separates which lobes?
it seperates the parietal from the frontal lobe, also it seperates the primary motor lobe from the primary somatosensory cortex.
Where is the major part of the somatosensory cortex located?
The major part of the somatosensory cortex is located in the postcentral gyrus of the parietal lobe in the brain. This area is responsible for processing sensory information from the skin and muscles.
The primary somatosensory area and primary motor area are separated by?
The primary somatosensory area and primary motor area in the brain are separated by the central sulcus, also known as the Rolandic fissure. This anatomical landmark divides the frontal lobe (where the primary motor area is located) from the parietal lobe (where the primary somatosensory area is located).
What sulcus separates the primary motor cortex fron the primary sensory cortex?
The central sulcus is a fold in the cerebral cortex of brains in vertebrates. Also called the central fissure, it was originally called the fissure of Rolando or the Rolandic fissure, after Luigi Rolando.The central sulcus is a prominent landmark of the brain, separating the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex.
The primary visual area is located in the?
Post central gyrus of the parietal lobe in the cerebral cortex of the brain.

What is post- central gyri?
The postcentral gyri are located in the parietal lobe of the brain and are involved in processing somatosensory information, such as touch, temperature, and proprioception. They are part of the primary somatosensory cortex, where sensory information from the body is received and interpreted.
The primary somatosensory area and primary motor area are separated by?
The primary somatosensory area and primary motor area in the brain are separated by the central sulcus, also known as the Rolandic fissure. This anatomical landmark divides the frontal lobe (where the primary motor area is located) from the parietal lobe (where the primary somatosensory area is located).

What area is posterior to the central sulcus?
Postcentral gyrus, or the parietal lobe [Edit: The postcentral gyrus is posterior to the central sulcus, not anterior. The primary motor cortex is located directly anterior to the central sulcus.]
The primary visual area is located in the?
Post central gyrus of the parietal lobe in the cerebral cortex of the brain.
The primary somatosensory area and the primary motor area are separated by?
the central sulcus
What is located right behind the central sulcus?
The primary somatosensory cortex is located right behind the central sulcus. This region of the brain is responsible for processing sensory information from the body, such as touch, pain, and temperature.
Discuss the representation of tactile information in the mammalian cerebral cortex?
The DCML- Dorsal column mediated leminiscal - system is one of the central pathways of the somatosensory system. This system is involved in mediating fine and discriminating touch. A-beta fibrers such as the Meisnerr's corpuscles, Merkel disks, Ruffinni corpuscles and Pacinian corpuscles are involved in this pathway. They are called Tactile fibres. Axons from tactile afferents ascends spinal cord and synapse on the 2nd order of the Dorsal column nuclei of the medulla. Axons of the 2nd order neurons cross to other side of brainstem and ascend to the VP (ventral posterior) complex of thalamic nuclei. The 3rd order of the thalamic nuclei project onto the primary somatosensory cortex of the mammalian brain where the information is processed. The cerebral cortex consists of 2 types of neurons- the pyramidal neurons which is excitatory; and stellate neurons which are excitatory and inhibitory. The 3rd neuron has its cell body still in the VP of the thalamic nuclei and ends in the parietal lobe- the postcentral gyrus.
What separate the frontal and parietal lobes?
Central Sulcus
What is difference between suture and sulcus?
Suture is a fibrous connective tissue joint between two or more structures (e.g. bones in the brain). For example, there is a sagittal suture between the two parietal bones of the skull. Sulcus is the fissure on the surface of the brain which surrounds the gyri. For example, there is a central sulcus which separates the frontal and parietal lobes of the cerebral cortex.
