Lobes Flashcards
Lateral premotor (frontal)
Actions initiated by external cues
Important for linking action with objects in the environment
Primary motor cortex (frontal)
Executes all voluntary movements if the body
Somatopically organized and crossed (left hemisphere= right side of body)
lesions results in paralysis
Medial premotor
Supplementary motor area (frontal lobe)
Internally generated actions
Involved in well learned actions
Action routines not created from scratch each time
Scripts/schemas
Frontal eye fields (frontal lobe)
Eye movements guided by external cues
Thalamus
Subcortical
Relay center for sensory info to the cerebral cortex
Lateral geniculate nucleus to V1
Medial geniculate nucleus to auditory cortex
Primary gustatory cortex- taste (disgust)
Temporal-parietal junction
Eye gaze (Social info)
Perception of biological motion (living things in general)
Moving mouths
Lesions disrupt performance on ToM tests
Temporal lobe
“What” route (what am I hearing, what am I seeing?)
Language (semantics)
Faces, animals, tools
Temporal poles
Language and semantic memory
Provides current social or emotional context
Superior temporal sulcus (STS)
Processing social information conveyed by gaze shifts (approach vs.avoidance)
Medial PFC (frontal)
Game playing task involving cooperation
Mentalizing
Understanding irony
Metaphors
Reasoning about self and others
rTPJ
Reasoning about other people’s mental states
Cross-modal integration (parietal lobe)
Hearing, touch & vision are integrated via space
Multiple sensory inputs essential to comprehend surrounds
Damage to parietal lobes
Balint’s syndrome (severe spatial disturbance)
Neglect
Maps (parietal lobe)
Egocentric- relative to position of body
Retinocentric- relative to position to the eye gaze
Allocentric- objects & places relative to each other
Parietal lobe
“Where” route
hearing where is an object in relationship to me
