What is the right inferior frontal gyrus?
What is the right inferior frontal gyrus?
The right inferior frontal gyrus (IFG) has been associated with various cognitive functions, including attention, motor inhibition and imagery, as well as social cognitive processes or speech functions (Corbetta and Shulman 2002; Hamilton and Grafton 2008; Aron 2011; Lai et al.
Which functional area is located in the inferior frontal gyrus?
The inferior frontal gyrus, located below the inferior frontal sulcus, corresponds to Broca’s area on the left [13].
What is the function of the superior frontal gyrus?
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 is the function of the middle frontal gyrus?
[4] Inferior to the superior frontal gyrus, and separated from it by the superior frontal sulcus, is the middle frontal gyrus. The dominant (left) middle frontal gyrus plays a key role in the development of literacy, while the nondominant (right) middle frontal gyrus is responsible for numeracy.
What is RIFG?
RIFG Meaning. 3. rIFG. Right Inferior Frontal Gyrus + 1 variant. Neurology, Medical.
What does the left inferior frontal gyrus control?
The left inferior frontal gyrus (IFG) is a key node of the neural networks engaged in language processing in the human brain and has been subdivided in several areas crucial for different aspects of language processing.
Where is the inferior left frontal lobe?
The inferior surface of the frontal lobe is the smallest cortical surface of the lobe, located anterior to the stem of the Sylvian fissure, lying on the floor of the anterior cranial fossa. It is divided into two parts, by two sulci.
What is in the frontal lobe?
The frontal lobes are involved in motor function, problem solving, spontaneity, memory, language, initiation, judgement, impulse control, and social and sexual behavior.
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 other main gyrus of the frontal lobe is the precentral gyrus which is vertically oriented, and runs parallel with the precentral sulcus.
What is the function of the Precuneus?
The precuneus is a brain region involved in a variety of complex functions,60 which include recollection and memory, integration of information (gestalt) relating to perception of the environment, cue reactivity, mental imagery strategies, episodic memory retrieval, and affective responses to pain.
What artery supplies the middle frontal gyrus?
The frontal cortex receives its blood supply from two branches of the internal carotid artery: the anterior cerebral arteries and the middle cerebral arteries. The superior and medial aspects of the cortex receive its supply from the smaller anterior cerebral artery.
What are functions of left inferior frontal gyrus?
Functions specific to the left inferior frontal gyrus include many language-related tasks. Part of the human ability to comprehend syntax and syntactic processing as well as overall language comprehension seems to be located in this area. Multiple studies have related overall language fluency to this area.
Where are the gyrus located in the brain?
These regions included three areas in the left hemisphere: the dorsal middle frontal gyrus, the inferior frontal gyrus, and the superior temporal gyrus. These regions all grew significantly. There was also some, more selective and smaller, growth in the middle frontal gyrus and inferior frontal gyrus in the right hemisphere.
Is the inferior frontal gyrus posterior to the ascending ramus?
Opercular part of inferior frontal gyrus (pars opercularis), (cortex posterior to the ascending ramus of the lateral sulcus), and part of frontal lobe that overlies the insular cortex Triangular part of inferior frontal gyrus (pars triangularis), (cortex between the ascending ramus and the horizontal ramus of the lateral sulcus)
What makes up the inferior surface of the frontal lobe?
The inferior frontal gyrus makes up the lateral and inferior surface of the frontal lobe, and is separated from the middle frontal gyrus above by the inferior frontal sulcus. It contains the frontal operculum (hiding the anterosuperior part of the insular cortex ). Its inferior edge abuts the lateral sulcus…

Is the inferior gyrus in the dominant hemisphere?
The inferior-most of the three major longitudinal gyri of the lateral surface of the frontal lobe of each cerebral hemisphere; it is part of the prefrontal cortex. In the dominant hemisphere, the posterior two-thirds of the inferior frontal gyrus are Broca speech area, which is involved in activating the muscle groups used when speaking
