Cortical is a word referring to the cortex, so the subcortical region of the brain is literally 'anything beneath the cortex'; but, since the brain isn't arranged in flat layers, it may be easier to visualise this analogy: If you picture the brain as being half an orange, the outer skin (the zest) would equate to the grey matter of cerebral cortex, & the inner skin (the pith) to the white matter; everything else (the pulp & the pips of the orange) represents the subcortical structures, which include various ventricles & nuclei, the thalamus, hypothalamus, cerebellum, & the parts that make up the brainstem. Subcortical pathways enable fast, unconscious reactions; so a reflex is a subcortical action.

∙ 14y agoThere are many functions of the subcortical brain, sometimes referred to as the archeocortex. This contains the diencephalon, the lymbic system, the cerebellum and the brain stem. All of these parts serve unique and specialized functions. The brain stem is what keeps is alive. It is the most inferior (lowest) portion of the brain and it controls the cardiac and respiratory functions of the body.

The part of the newborn brain that is the least develped?
The newborn baby functions mostly at the subcortical level. Cortical functions are not well developed at birth.
What are the functions of diencephalon in the brain?
The diencephalon is the region of the brain that sits on top of the brainstem, below the telencephalon. It includes the thalamus and hypothalamus. Parts of diencephalon perform numerous functions, from regulating wakefulness to the control of the autonomic nervous system.
The second largest region of the brain is called?
the largest region of the brain if the pooluntush membrane
What is the major organ that controls all the functions and actions of a human body?
the brain guys the brain x
Compartmentalization of function refers to what part of the brain?
different brain regions perform distinct functions
The part of the newborn brain that is the least develped?
The newborn baby functions mostly at the subcortical level. Cortical functions are not well developed at birth.
What is the meaning of the word subcortical?
The term subcortical refers to structures or processes that lie beneath the cerebral cortex in the brain. These subcortical structures are involved in functions such as regulating emotions, motor control, and processing sensory information.
Can cerebellum come out your nose?
No, your cerebellum is a region of your brain that controls your motor functions.
Function of white matter in the brain?
The white matter is the area of the brain where signals travel to other parts of the brain. It is located in the subcortical area.
What are groups of neurons send connections from the cortex deep into the brain?
These are called 'projection neurons'. The cell body in the cortex will have a long axonal projection that courses down into a subcortical region, and vice versa.
Can epileptic seizures be found in the subcortical of the brian?
yes epileptic seizures can be found in the sub-cortical of the Brain's of the type of seizures are all over the brain .
What are the functions of diencephalon in the brain?
The diencephalon is the region of the brain that sits on top of the brainstem, below the telencephalon. It includes the thalamus and hypothalamus. Parts of diencephalon perform numerous functions, from regulating wakefulness to the control of the autonomic nervous system.
WHAT model of dreaming proposes that dreams are side-effects of neural activity in subcortical areas of the brain?
activation-synthesis model
Are the limbic and subcortical regions of the brain the same?
'Subcortical structures' are areas of the brain below the cortex, which is the outermost layer (i.e., the grey matter). The limbic system is one example of a subcortical structure - although technically it isn't just one structure. The limbic system actually consists of a number of key areas related to sensory integration, learning, memory, emotionality, and decision-making. See: http://en.wikipedia.org/wiki/Limbic_system
What are the functions of the dopamine receptor 5?
The receptors are located primarily in the limbic system of the brain. The limbic system is a region in the brain containing structures such as the hippocampus and amygdala. The region plays a role in a variety of functions such as emotion and behavior, long-term memory and smell.
What does it mean when there are multiple abnormal foci of high T2 signal scattered along the subcortical and periventricular region?
Your physician should explain you the protocol, but I can try to help a bit though i'd need more details. This is the protocol of a Magnetic Resonance scan (MRI, MRT, KST,... it has many names), i assume of your brain. They see multiple nodes that give a high signal on T2 images. Basically, they see nodes, and the fact that they light up on T2 tells you something about their contents. On T2 images, what lights up has a density about the same as water. About the subcortical and periventricular: this is just the region, subcortical = under the cortex. The cortex is the outer rim of your brain. Periventricular = around the ventricle, a ventricle is a chamber of cerebrospinal fluid in your brain. All things together, my guess (can only guess as i don't have more details and can't see the images), is that these are cysts.
What is an operation on a thalamic bleed?
This involves a neurosurgical operation in which a subcortical structure of the brain known as the thalamus has a bleeding vessel needing to be cauterized or tied off.
