gyrus vs. sulcus Discover More Example Sentences The electrical signals, lasting on average 120 milliseconds, were then found to move down and across the folds of the precentral gyrus to a neighboring auditory cortical subregion, called the superior temporal gyrus. From Science Daily MRI scans reve...
In particular, a reliable circuitry is engaged in processing the social information decoded from faces, including the amygdala, fusiform gyrus (fusiform face area [FFA]), inferior frontal gyrus (IFG)/OFC, and superior temporal sulcus (STS) (Adolphs, 1999, 2002). In an fMRI study of patients...
The meaning of ANGULAR GYRUS is the cerebral gyrus of the posterior part of the external surface of the parietal lobe that arches over the posterior end of the sulcus between the superior and middle gyri of the temporal lobe —called also angular convolu
is involved in integration between representations and consists of three subsections.Supramarginal gyrusarches over the upturned end of the lateral fissure,angular gyrusarches over thesuperior temporal sulcus, andinferior parietal lobuleis superior to these twogyriand lies below theintraparietal sulcus. ...
(~ PGa) and adjacent intraparietal sulcus (IPS) showed increased activity for semantic tasks with a higher executive demand. In contrast, left ventral AG (~ PGp) was engaged for semantic vs. phonological tasks, but insensitive to executive demands. Accordingly, the “controlled semantic ...
Gross anatomy of the angular gyrus The AG is often described as the gyrus surrounding the angular sulcus (as). However, this sulcus is not only highly variable across brains, but also hemispheres (Eidelberg and Galaburda 1984). It arises as the posterior termination of the superior ...
respectively. The anterior part of the collateral sulcus is also termedrhinal sulcus. Smaller sulci can often be recognized on the inferior and medial surface, such as the temporopolar sulcus that defines the posterior border of the temporal pole and the semianular sulcus. The latter sulcus i...
This is a deep cleft at right angles to the central sulcus. The somatosensory association cortex (BA 5) is a small area in the superior parietal lobule, just behind the sensory strip. Lesions here may lead to astereognosia: the inability to recognize objects by touch (Greek: a-, without...

These demarcate the superior frontal gyrus (above the superior frontal sulcus), inferior frontal gyrus (below the inferior frontal sulcus), and middle frontal gyrus between the two. These are well shown on coronal MR images. The precise pattern of sulcation varies a great deal, but most ...
