31 Cards in this Set
- Front
- Back
|
Hemispheric Lateralization
- Right Side |
"creative"
-musical & artistic awareness -spatial and pattern perception -FACE RECOGNITION -emotional part of speech |
|
|
central sulcus of frontal lobe
|
separates frontal and parietal lobes
|
|
|
Primary motor cortex
|
= ** PRECENTAL GYRUS
-directs voluntary muscle movement -contains a map of all skeletal muscles |
|
|
broca's speech area
|
primarily located in left hemisphere-produces speech
- EPRESSIVE (MOTOR, NON-FLUENT) APHASIA ---ANOMIA (INABILITY TO NAME OBJECTS) -patient aware of deficit |
|
|
primary somatosensory cortex
|
= POSTCENTRAL GYRUS
-receives somatic sensory information from skin receptors, joints and muscles |
|
|
hemispheric lateralization
left side |
"analytical"
-spoken and written LANGUAGE -numerical and scientific skills -reasoning |
|
|
pyramidal neurons function
|
they project using the INTERNAL CAPSUL to synapse in the brainstem or the spinal cord
they talk to the neurons that contact the muscles (the don't directly synapse on the muscles) |
|
|
premotor cortex
|
planning of motor activities
two regions -frontal eye fields -Broca's speech area |
|
|
syndrome of hemineglect
|
stroke to the right parietal association cortex results in the patient disregarding the left side of their body
|
|
|
primary auditory cortex
|
receives sound info, sorts by frequency (tonotopic map)
-pitch and rhythm |
|
|
receptive aphasia
|
-language comprehension is affected
-nonsensical speech/pt is unaware -anomia, impairs repetition and non fluent reading -apraxia |
|
|
wernicke's speech area
|
primarily located in left hemisphere-
speech comprehension |
|
|
apraxia
|
inability to execute motor activity based on verbal command
|
|
|
what is found in the frontal lobe?
|
Broca's area
Frontal eye field prefrontal cortex premotor cortex primary motor cortex |
|
|
what is found in the occipital lobe?
|
primary visual cortex
|
|
|
what is found in the parietal lobe
|
primary somatosensory cortex
wenicke's area |
|
|
what is found in the temporal lobe?
|
limbic lobe
primary auditory cortex |
|
|
primary motor cortex
|
responsible for fine motor control
|
|
|
prefrontal cortex
|
responsible for vague limbic functions (personality)
|
|
|
premotor cortex
|
responsible for motor planning
|
|
|
primary somatosensory cortex
|
responsible for detecting find sensory information
|
|
|
primary visual cortex
|
damage results in blindness
|
|
|
wenicke's area
|
damage results in fluent (receptive, sensory) aphasia
|
|
|
frontal eye field
|
damage results in deviation of eye to side of injury
|
|
|
somatosensory association cortex
|
damage results in syndrome of hemineglect- in which individuals avoid the left side of objects
ex) only copying info from the left side of a paper |
|
|
broca's area
|
damage results in non-fluent (expressive, motor) aphasia
|
|
|
anomia
|
when someone can't name something
|
|
|
apraxia
|
can't execute a motor activity based on verbal command
|
|
|
aphasia
|
is a problem with one's language
|
|
|
motor/expressive
|
broca's aphasia, when one can't talk
|
|
|
sensory/receptive
|
wenicke's aphasia, can't understand
ex)reading |
