Hearing, Speaking, Stimulation, and Movement Flashcards
Description of language
Language is the use of complex systems of communication and includes syntax
Relationship between frequency, amplitude, pitch, and loudness of sound waves
Frequency of sound waves corresponds to pitch, amplitude corresponds to loudness
Name and order of the middle ear bones
Hammer, anvil, stirrup
Location of the human A1 auditory area
Heschl’s gyrus
Location of Broca’s area
Anterior speech area in the LEFT HEMISPHERE
Wernicke’s area
Posterior speech area at the rear of the LEFT TEMPORAL LOBE
Broca’s aphasia
Inability to speak fluently despite having normal comprehension and intact vocal mechanisms
Wernicke’s aphasia
Inability to understand or produce meaningful language even though the production of words is still intact
Role of the left hemisphere in music
Recognizing written music, playing instruments, and composing music
Functions of birdsong
Attracting mates, demarcating territories, and announcing locations
Instances when the motor cortex is activated
Planning movement, watching people do movement
Sequence of producing movement within the CNS
- Visual cortex
- Cortical somatosensory regions
- Motor regions
- Spinal cord
Roles of the spinal cord in movement
Conveys sensory and motor information between brain and body; reflexive behaviors; walking
Early research vs. recent research perspectives on the role of the motor cortex
Early research: each part of the homunculus controls individual muscle movements
Recent research: the motor cortex doesn’t represent muscles but rather a repertoire of fundamental movement categories
Succession of events leading up to movement
- Identification of objects by visual and auditory cortices
- Transmission of information to the somatosensory cortex
3 Identification of useful body part - Transmission to motor cortex
- Movement
