What are the cortical areas and what do they do?
The cortex can be divided into three functionally distinct areas: sensory, motor, and associative. The main sensory areas of the brain include the primary auditory cortex, primary somatosensory cortex, and primary visual cortex. In general, the two hemispheres receive information from the opposite side of the body.
Where are cortical areas?
Cortical areas are areas of the brain located in the cerebral cortex. The cerebral cortex refers to the superficial part of the brain and containing the gray matter of the cerebral hemispheres. The human brain. The peripheral part of the brain is called the cerebral cortex.
What does the dorsolateral prefrontal cortex do?
The dorsolateral prefrontal cortex has been found to be involved in superordinate control functions for various cognitive tasks such as decision making, novelty detection, working memory, conflict management, mood regulation, theory of mind processing, and timing.
What is the cortico striatal circuit?
The cortico-striatal-thalamo-cortical (CSTC) pathway is a brain circuit that controls movement execution, habit formation and reward. Hyperactivity in the CSTC pathway is involved in obsessive compulsive disorder (OCD), a neuropsychiatric disorder characterized by the execution of repetitive involuntary movements.
What are the important cortical areas?
Functional Divisions of the Cerebral Cortex
| Cortical Area | Function |
|---|---|
| Prefrontal Cortex | Problem Solving, Emotion, Complex Thought |
| Motor Association Cortex | Coordination of complex movement |
| Primary Motor Cortex | Initiation of voluntary movement |
| Primary Somatosensory Cortex | Receives tactile information from the body |
How many cortical areas are there?
Cortical areas. The whole of the cerebral cortex was divided into 52 different areas in an early presentation by Korbinian Brodmann. These areas known as Brodmann areas, are based on their cytoarchitecture but also relate to various functions. An example is Brodmann area 17 which is the primary visual cortex.
What activates the dorsolateral prefrontal cortex?
In healthy control subjects, tasks involving executive functions, such as working memory, inhibition, or attentional switching, typically activate prefrontal regions that overlap with those involved in processing and regulating emotion, including the medial prefrontal cortex (PFC) and orbitofrontal cortex, anterior …
Where is the dorsolateral prefrontal cortex?
the frontal lobe
The dlPFC is located on the lateral and dorsal part of the medial convexity of the frontal lobe and comprises BA 9 and 46 and a few transitional areas: 9-8, 9-45, 46-10, and 46-45 (for a detailed description of anatomical boundaries, see (Rajkowska and Goldman-Rakic, 1995b, a).
Where does the afferent dopaminergic projection to the striatum originate?
Afferent projections to the striatum are derived from three major sources: (i) a massive and topographic input from the cerebral cortex; (ii) input from the thalamus; and (iii) and input from the brain stem, primarily from the brain stem dopaminergic cells.
