What does the inferior frontal gyrus do?

Function. The inferior frontal gyrus has a number of functions including the processing of speech and language in Broca’s area. Neural circuitry has been shown to connect different sites of stimulus to other regions of response including other subdivisions and also other frontal gyri.

What is the role of the frontal cortex in emotional response?

The frontal lobes are considered our emotional control center and home to our personality. It’s involved in motor function, problem solving, spontaneity, memory, language, initiation, judgment, impulse control, and social and sexual behavior.

How does damage to the prefrontal cortex affect emotions?

Deficits in emotion recognition can be seen by either direct damage to the inferior frontal gyrus, or via damage to dorsal lateral prefrontal cortex regions, resulting in deteriorated performance and less EEG mu suppression over sensorimotor cortex.

What supplies the inferior frontal gyrus?

The superior and medial aspects of the cortex receive its supply from the smaller anterior cerebral artery. In comparison, the inferior and lateral aspects receive supply from the much larger middle cerebral artery.

What does the superior frontal gyrus do?

The superior frontal gyrus (SFG) is thought to contribute to higher cognitive functions and particularly to working memory (WM), although the nature of its involvement remains a matter of debate. To resolve this issue, methodological tools such as lesion studies are needed to complement the functional imaging approach.

What does Broca’s area do?

Broca’s area is a key component of a complex speech network, interacting with the flow of sensory information from the temporal cortex, devising a plan for speaking and passing that plan along to the motor cortex, which controls the movements of the mouth.

What part of the brain controls sadness?

The limbic system
The limbic system is a group of interconnected structures located deep within the brain. It’s the part of the brain that’s responsible for behavioral and emotional responses.

What part of the brain controls emotional regulation?

limbic system
The limbic system refers to the set of structures in the brain that plays an important role in emotional regulation and is responsible for the regulation of autonomic and endocrine function in response to emotional stimuli.

Does anxiety affect the prefrontal cortex?

Neuroimaging studies repeatedly show abnormalities in the prefrontal cortex in anxious individuals. Thus, we suggest that the very same cortical complexity that allows us to produce a vibrant culture is also the seat of anxiety disorders.

What is frontal gyrus?

The frontal gyri are four gyri of the frontal lobe in the brain. These are four horizontally oriented, parallel convolutions, of the frontal lobe. The inferior frontal gyrus includes Broca’s area. The lowest part of the inferior frontal gyrus rests on the orbital part of the frontal bone.

What is the function of the inferior frontal gyrus?

The inferior frontal gyrus is the location of Broca’s area involved in language processing and speech production.

What is the superior border of the temporal gyrus?

Its superior border is the inferior frontal sulcus (which divides it from the middle frontal gyrus ), its inferior border is the lateral sulcus (which divides it from the superior temporal gyrus) and its posterior border is the inferior precentral sulcus.

What is Brodmann area 44 in the brain?

Cytoarchitecturally the opercular part of the inferior frontal gyrus is known as Brodmann area 44 (BA44). The triangular part of the inferior frontal gyrus is known as Brodmann area 45 (BA45), and the orbital part of the inferior frontal gyrus is known as Brodmann area 47.
