Is the superior longitudinal fasiculus a unidirectional pathway or a bidirectional pathway?
Bidirectional
Which fiber bundle functions primarily to implement goal-related motor actions?
Superior longitudinal fasciculus III (SLF III)
What does the superior longitudinal fasciculus II (SLF II) mediate?
Spatial awareness, visual attention, and spatial working memory
What are the three primary disorders of the uncinate fasciculus (UF)?
Schizophrenia, epilepsy, poor self-regulation
