The Unique Fiber Anatomy of Middle Temporal Gyrus Default Mode Connectivity.

ABSTRACT:

Background

The middle temporal gyrus (MTG) is understood to play a role in language-related tasks such as lexical comprehension and semantic cognition. However, a more specific understanding of its key white matter connections could promote the preservation of these functions during neurosurgery.

Objective

To provide a detailed description of the underlying white matter tracts associated with the MTG to improve semantic preservation during neurosurgery.

Methods

Tractography was performed using diffusion imaging obtained from 10 healthy adults from the Human Connectome Project. All tracts were mapped between cerebral hemispheres with a subsequent laterality index calculated based on resultant tract volumes. Ten postmortem dissections were performed for ex vivo validati
