Introduction to the cortex Flashcards
What is Wernicke’s aphasia
a type of auditory agnosia
the individual is unable to understand language in its written or spoken form
What is Broca’s aphasia
individuals have trouble speaking fluently but their comprehension is relatively presevered (non fluent/expressive aphasia)
can be caused by a stroke
what is the name for face blindness
prosopagnosia
what is the name for difficultly understanding pitch and music
Amusia
what is ocular ataxia
difficulty controlling eye movement
what is the majority of the neocortex function
association area
integrates information from other brain regions
where cognition occurs
where does the cerebellum output to
projects to brainstems motor nuclei, vestibular nuclei, muscle spindles, motor and pre motor cortices via the thalamus
what are the cerebellar inputs (via the superior, middle and inferior peduncles
proprioception
spinal reflexes
visual, auditory and motion brainstem
somatosensory and premotor cortex via the olives
what are the three layers of the cerebellar cortex
molecular layer
purkinje cell layer
granule cell layer
what two types of information does the cerebellum mainly compare
ascendigng sensory information with descending premotor information and feeds back to the cerebral cortex
where is the primary auditory cortex
temporal lobe
also involves the medial geniculate nucleus which is part of the thalamus
where is the primary visual cortex
most posterior part of the occipital lobe
around the calcarine fissure
what are primary cortical regions
receive information from the thalamus with relatively little processing
where is the primary olfactory cortex
anterior temporal lobe (piriform cortex)
what are the two types of association areas
unimodal and poly modal
