What is the function of gray matter in the brain and spinal cord?
Gray matter is formed from neuronal cell bodies and dendrites.
What is white matter in the brain and spinal cord formed from?

What is the primary termination zone of the visual pathway in the occipital cortex?
V1
What is the primary motor cortex called?
PreCentral Gyrus
What are gyri and sulci?
Gyri are the folds on the surface of the cerebral cortex, while sulci are the grooves between the folds.
What is the difference between gyri and fissures?
Gyri are the folds on the surface of the cerebral cortex, while fissures are the deepest grooves between gyri.
What is the composition of the neocortex?
The neocortex has six layers and its composition varies depending on specialization, such as sensory or motor.
What are the major gyri and sulci of the human cerebrum?
The major gyri include the superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus, precentral gyrus, postcentral gyrus, superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus, supramarginal gyrus, angular gyrus, superior parietal lobule, middle occipital gyrus, and inferior occipital gyrus. The major sulci include the lateral fissure, central sulcus, parieto-occipital sulcus, calcarine sulcus, cingulate sulcus, and subparietal sulcus.
What are the four major parts of the brain?

White matter in the brain and spinal cord is formed from aggregations of myelinated axons from many neurons.
What is the primary termination zone of the visual pathway in the occipital cortex called?
The primary termination zone of the visual pathway in the occipital cortex is called the striate cortex (also known as primary visual cortex or V1).
What is the name of the fold of dura that lies in the fissure separating the cerebral hemispheres?
The fold of dura that lies in the fissure separating the cerebral hemispheres is called the falx cerebri.
What are the two types of grooves created in the cortex during embryonic development?
The two types of grooves created in the cortex during embryonic development are fissures and sulci.
What is the name for the deepest grooves between gyri?
The name for the deepest grooves between gyri is fissures.
What is the term for the shallower grooves between folds?
The term for the shallower grooves between folds is sulci.
What are the six layers of the neocortex?
The six layers of the neocortex are: molecular, external granular, external pyramidal, internal granular, internal pyramidal, and multiform.
What is the primary auditory cortex called?
The primary auditory cortex is called Heschl's Gyrus.
What are the major gyri and sulci of the human cerebrum?
The major gyri and sulci of the human cerebrum are: superior frontal gyrus, middle frontal gyrus, inferior frontal gyrus, precentral gyrus, postcentral gyrus, superior temporal gyrus, middle temporal gyrus, inferior temporal gyrus, supramarginal gyrus, angular gyrus, superior parietal lobule, middle occipital gyrus, inferior occipital gyrus, and Heschl's Gyrus.
What is the primary termination zone of the visual pathway in the occipital cortex?
V1
What is the primary motor cortex called?

What are gyri and sulci?
Gyri are ridges of brain cortex, while sulci are CSF-filled grooves that separate gyri
What is the composition of the neocortex?
It is composed of gray matter mantle that overlies white matter
What is white matter in the brain and spinal cord formed from?
White matter is formed from myelinated axons
