313
Q

Function IFOF

A

The inferior fronto-occipital fasciculus (IFOF) is a large white matter tract of the human cerebrum with functional connectivity associated with semantic language processing and goal-oriented behavior.

314
Q

Function SLF II

A

SLF II is the major component of SLF and originates in the caudal-inferior parietal cortex and terminates in the dorsolateral prefrontal cortex (Brodmann 6, 8 and 46).

SLF II connects to the caudal inferior parietal cortex which controls spatial attention and visual and oculomotor functions. This suggests the SLF II provides the prefrontal cortex with parietal cortex information regarding perception of visual space. Since these bundles are bi-directional, working memory (Brodmann 46) in the prefrontal cortex may provide the parietal cortex with information to focus spatial attention and regulate selection and retrieval of spatial information.

315
Q

Function MLF

A

The medial longitudinal fasciculus (MLF) is a myelinated composite fibre tract found in the brainstem. The MLF primarily serves to coordinate the conjugate movement of the eyes and associated head and neck movements.

316
Q
A

ILF

317
Q

Function ILF

A

The inferior longitudinal fasciculus carries visual information from occipital areas to the temporal lobe (Catani et al., 2003a) and it is likely to play an important role in visual object recognition, semantic processing and in linking object representations to their lexical labels

318
Q
A

Uncinate fasciculus

319
Q

Function uncinate fasciculus

A

Function. The function of the uncinate fasciculus is not known, though it is traditionally considered to be part of the limbic system.. It has been proposed that the uncinate fasciculus allows mnemonic representations stored in the temporal lobe to interact with and guide decision making in the frontal lobe

Etymology- carotid

A

from the greek “karotis”

early 17th century: from French carotide or modern Latin carotides, from Greek karōtides, plural of karōtis ‘drowsiness’, from karoun ‘stupefy’ (because compression of these arteries was thought to cause stupor).

336
Q

Etymology- sphenoid

A

mid 18th century: from modern Latin sphenoides, from Greek sphēnoeidēs, from sphēn ‘wedge’.
