Frontal Lobe
|
Executive Function (planning, organising, and reasoning)
Broca's Area - Programs speech movements and syntax |
|
|
Parietal lobe:
|
• Sensation
Angular Gyrus - Involved in processing and visual input and in comprehension of language |
|
|
Temporal lobe
|
Auditory processing/ semantics
Wernicke's Area - language comprehension/production |
|
|
Occipitial lobe
|
VisionSecondary visual areas - integrate visual information, memory storage
|
|
|
Role of cerebral cortex in swallowing
|
1. Facilitates initiation of pharyngeal swallow and modifies the duration and intensity of oral and pharyngeal muscle activity - alters the sensory threshold for reflex swallowing.
2. Integrates learned (orofacial movements) with patterned sequence of pharyngeal activity |
