What makes up the dorsolateral prefrontal cortex?
Historically, the DLPFC was defined by its connection to: the superior temporal cortex, the posterior parietal cortex, the anterior and posterior cingulate, the premotor cortex, the retrosplenial cortex, and the neocerebellum.
What does Brodmann area 8 do?
Brodmann area 8, or BA8, is part of the frontal cortex in the human brain. Situated just anterior to the premotor cortex (BA6), it includes the frontal eye fields (so-named because they are believed to play an important role in the control of eye movements).
What are the parts of the prefrontal cortex?
In mammalian brain anatomy, the prefrontal cortex (PFC) is the cerebral cortex which covers the front part of the frontal lobe….
| Prefrontal cortex | |
|---|---|
| Part of | Frontal lobe |
| Parts | Superior frontal gyrus Middle frontal gyrus Inferior frontal gyrus |
| Artery | Anterior cerebral Middle cerebral |
Which eye movements are controlled by Brodmann’s area 8 of the frontal lobes?
Saccades are fast conjugate eye movements that are under voluntary control. Saccades are generated in the contralateral frontal lobe (Brodmann’s area 8).
What is the dorsolateral prefrontal cortex?
The dorsolateral prefrontal cortex is a region of the frontal lobes that is most typically associated with executive functions including working memory and selective attention (Curtis & D’Esposito, 2003).
Where is the dorsolateral frontal cortex located?
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).
What is Brodmann area1?
For example, Brodmann area 1 is the primary somatosensory cortex, Brodmann area 17 is the primary visual cortex, and Brodmann area 25 is the anterior cingulate cortex.
Why are Brodmann areas important?
Brodmann areas 23, 24, 28 and 33 – Cingulate gyrus It is an important part of the limbic system, helping to regulate emotions and pain.
What are the major areas of the prefrontal cortex?
It has two major anatomical and functional subdivisions: the orbitomedial and the dorsolateral prefrontal regions. The Orbitomedial cortex is involved in sensory processing (taste and olfaction), regulation of the internal environment, control of drives, and emotional behavior.
How many neurons are in the prefrontal cortex?
Not surprisingly, the same 8% of all cerebral cortical neurons found in the prefrontal region correspond to a much larger absolute number of neurons in human (1.3 billion) than in other primate brains (e.g., macaque, 137 million), regardless of the relative size of the prefrontal cortex.
