What is the gray matter on the surface of the brain called?
Grey matter is distributed at the surface of the cerebral hemispheres (cerebral cortex) and of the cerebellum (cerebellar cortex), as well as in the depths of the cerebrum (thalamus; hypothalamus; subthalamus, basal ganglia - putamen, globus pallidus, nucleus accumbens; septal nuclei), cerebellar (deep cerebellar nuclei - dentate nucleus, globose nucleus, emboliform nucleus, fastigial nucleus), brainstem (substantia nigra, red nucleus, olivary nuclei, cranial nerve nuclei) and spinal grey matter (anterior horn, lateral horn, posterior horn).
What is the cerebral lobe located deep within lateral sulcus?
Insula
Is it true or false that the deep grooves within the cerebral hemispheres are known as gyri?
False. The deep grooves within the cerebral hemispheres are known as sulci, while the raised folds are called gyri.
Do cows dream?
yes they like humans have a cerebral invert cortex which allows their memories to resuface while they are in a deep relaxed state of mind a synopsis or sleep
What is the nuclei deep within the cerebral hemisphere white matter are collectively?
basal ganglia
What is internal capsule and why it is given that name?
It is a broad lamina of white matter made up of projection fibres which pass to and from the cerebral cortex.It's called as "internal capsule" simply because it forms an internal (inner) capsule to the lentiform nucleus.
What is cortical and central cerebral atrophy?
Cortical cerebral atrophy refers to a loss of neurons in the cerebral cortex, the outer layer of the brain responsible for higher brain functions. Central cerebral atrophy involves shrinking of structures deep within the brain, such as the hippocampus and thalamus. Both types of atrophy can result in cognitive decline and neurological symptoms.
Where are the sub cortical motor centers?
Subcortical motor centers are located deep within the brain and include structures such as the basal ganglia and cerebellum. They play a crucial role in regulating movement, coordination, and motor learning. These regions interact with the cerebral cortex to control voluntary movements.
What part of the cerebral cortex do sensations and emotions come together?
Sensations and emotions come together in the limbic system, which is located deep within the brain and includes structures such as the amygdala and hippocampus. These areas are involved in processing emotions and linking them to sensory experiences.
Where is the insular cortex?
The insular cortex (abbrev. insula) is a structure of the human brain. It lies deep to the brain's lateral surface, within the lateral sulcus which separates the temporal lobe and inferior parietal cortex.
What color is the cortex?
This depends upon which cortex you are asking about. The cerebral cortex is a cream-white color unless it is fixed in formalin, at which point it turns gray. The renal cortex is a deep reddish-brown color and the adrenal cortex is a grayish-brown color.
What is nuclei deep within the cerebral hemisphere white matter are collectively called?
The nuclei deep within the cerebral hemisphere white matter are collectively called basal ganglia. These structures are involved in many motor functions and play a role in various cognitive functions as well.
