Subcortical: below the cerebral cortex. Subcortical structures are not visible when looking at the surface of the brain, and include structures like the hippocampus, thalamus, and hypothalamus (among many others).

Keeping this in view, what are the subcortical regions of the brain?

Subcortical structures are a group of diverse neural formations deep within the brain which include the diencephalon, pituitary gland, limbic structures and the basal ganglia. They are involved in complex activities such as memory, emotion, pleasure and hormone production.

Secondly, is the amygdala a subcortical structure? Subcortical areas: Septal nuclei: a set of structures that lie in front of the lamina terminalis, considered a pleasure zone. Amygdala: located deep within the temporal lobes and related with a number of emotional processes. Nucleus accumbens: involved in reward, pleasure, and addiction.

Considering this, where is the Subcortex in the brain?

The subcortex is the part of the brain that lies directly below the cerebral cortex. It consists of three main divisions. The basal ganglia, which lies in each hemisphere and is involved in motor control and skills learning.

What is the cortical region of the brain?

The cerebral cortex (plural cortices), also known as the cerebral mantle, is the outer layer of neural tissue of the cerebrum of the brain in humans and other mammals. It is separated into two cortices, by the longitudinal fissure that divides the cerebrum into the left and right cerebral hemispheres.

What are subcortical infarcts?

Description. Cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy, usually called CADASIL, is an inherited condition that causes stroke and other impairments. This condition affects blood flow in small blood vessels, particularly cerebral vessels within the brain.

How do cortical and subcortical strokes differ?

Strokes affecting the cerebral cortex (i.e. cortical strokes) classically present with deficits such as neglect, aphasia, and hemianopia. Subcortical strokes affect the small vessels deep in the brain, and typically present with purely motor hemiparesis affecting the face, arm, and leg.

What are the major brain regions?

The brain can be divided into three basic units: the forebrain, the midbrain and the hindbrain. These areas are: Occipital lobe, Temporal lobe, Parietal lobe, Frontal lobe. Cerebral cortex, Cerebellum, Hypothalamus,Thalamus,Pituitary gland, Pineal gland, Amygdala, Hippocampas and the Mid- brain.

What is the cerebrum responsible for?

The cerebrum is the largest part of the brain. It is responsible for memory, speech, the senses, and emotional response. It is divided into four sections called lobes: the frontal, temporal, parietal, and occipital.

What are the 4 parts of the brain and their functions?


Each hemisphere has four sections, called lobes: frontal, parietal, temporal and occipital. Each lobe controls specific functions. For example, the frontal lobe controls personality, decision-making and reasoning, while the temporal lobe controls, memory, speech, and sense of smell.

What part of the brain controls memory?

The main parts of the brain involved with memory are the amygdala, the hippocampus, the cerebellum, and the prefrontal cortex ([link]). The amygdala is involved in fear and fear memories. The hippocampus is associated with declarative and episodic memory as well as recognition memory.

What are the symptoms of subcortical dementia?

Subcortical dementia. Subcortical dementia is a type of dementia characterised by slowness of mental processing, forgetfulness, impaired cognition, apathy, depressive symptoms (such as anhedonia, negative thoughts, loss of self-esteem and dysphoria), loss of social skills and extrapyramidal disorders.

Is the cerebellum involved in memory?

Unlike the hippocampus which is involved in the encoding of complex memories, the cerebellum plays a role in the learning of procedural memory, and motor learning, such as skills requiring co-ordination and fine motor control.

Is the cerebral cortex gray matter?

The cerebral cortex is the outer surface of the cerebral hemispheres. It is the highest level of the brain and has about 20 billion neurons in the human brain which carry out the highest levels of mental functioning. The cerebral cortex is a layer of grey matter up to about 1/2 cm thick.

Where is the cerebellum located?

The cerebellum is located behind the top part of the brain stem (where the spinal cord meets the brain) and is made of two hemispheres (halves). The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements.

Is the cerebellum cortical or subcortical?

Cortical vs. Subcortical Strokes. A stroke may affect cortical regions of the cerebral cortex, including the frontal, parietal, temporal and occipital lobes, or structures subcortically, below the cortex, including the internal capsule, thalamus, basal ganglia, brainstem and cerebellum.

What is subcortical gray matter?

Subcortical gray matter. Known as: Internal gray matter component. Gray matter component of neuraxis which is located in the interior of the neuraxis. Example: thalamus, dentate nucleus, ventral horn of spinal cord.

What is the left parietal lobe responsible for?


This lobe is also important for pain and touch interpretation. Moreover, the parietal lobe is significant for interpreting words, as well as language understanding and processing (1). It helps interpret and realize temperature, vision, sensory, hearing, memory, and motor center signals, as well as visual perception.

What takes place in the cerebrum?

The frontal lobe, occipital lobe, temporal lobe and parietal lobe make up the cerebrum. The frontal lobe is responsible for problem-solving, voluntary body movement, sentence formation and personality. The occipital lobe is where processing of visual information takes place.

What is the cortex?

The cerebral cortex is the thin layer of the brain that covers the outer portion (1.5mm to 5mm) of the cerebrum. It is covered by the meninges and often referred to as gray matter. The cortex is gray because nerves in this area lack the insulation that makes most other parts of the brain appear to be white.
