Nervous [Lateral Brain +] Flashcards
Wernicke’s area function
Interprets tones.
Broca’s area function and location (in ____)
Frontal lobe in the motor planning area.
Vocalisation.
Frontal association complex function x 4
Intelligence, personality, behaviour, mood, cognitive function

Writing hand movements
Name of the structure that connects wernicke’s and broca’s. Function+ damage?
Arcuate fascilulus
Aligns speech comprehension with speech production.
Damage results in conduction aphasia
What are the left and right hemispheres for?
Left - verbal language
Right - non-verbal / body language
Parietal association complex function
Spatial skills 3D recognition (shapes, faces, concepts, abstract perception)
Differences between homonculus for sensory and motor areas in the RIGHT hemisphere
Sensory: many sensory neurons in face and lips. Less for arm then foot.
Motor: slightly more neurons for hand.
Non-dominant hemisphere features
Nonverbal language like body language Emotional expression (language tone) Spatial skills (3D) Conceptual understanding Artistic / musical skills
Effects of injury of right hemisphere
Loss of non-verbal language Speech lacks emotion Spatial disorientation Inability to recognise familiar objects Loss of musical appreciation
Broca’s area problems
Motor aphasia
Non-fluent
Can’t coordinate muscle movements required to produce speech despite knowing what they want to say
Wernicke’s area problems
Sensory aphasia
Involving sensation of hearing
Fluent
What is agraphia? Where?
Inability to understand reading or writing
Motor planning area damage
Can’t move right arm - spastic paralysis
Primary auditory cortex damage
Deafness
