Test 3 Material Flashcards
What does the parietal association cortex do?
analyzes space, generates attention, and transmits sensory information to the motor cortex
What does the temporal cortex do?
it organizes declarative memory, and is involved in high order visual and auditory processing
What is the frontal association cortex involved in?
executive functions: plans behavior, facilitates working memory, inhibits prepotent responses
What are common features of cortical regions?
1- primary input and output target 2- vertical exis 3- horizontal axis 4- cells with similar functions grouped radially 5- interneurons give rise to local axons
Projections from sensory cortices to the _______ are organized in both a parallel and ______ fashion.
PFC; heirarchecal
How are sensory cortices to the prefrontal cortex organized?
both parallel and hierarchical
Thalamic inputs to association cortices from from: (3 places)
1- mediodorsal thalamus
2- pulvinar
3- ventral anterior nucleus
Nuclei are not primary recipients of ____ or ____ inputs; instead they receive inputs from other _____ of _____.
sensory; motor; regions of cortex
Inputs from ____, _____ cortex, and ____ ____ cortices –> pontine nuclei
motor; premotor cortex; higher association cortices
What does the thalamus control?
upper motor neurons in the cortex
output from the cerebellar cortex goes to ____ _____ ____ and then via the superior cerebellar peduncle to the _____.
deep cerebellar nuclei; thalamus
The anterior zone of the parietal cortex is the ___ _____ cortex.
primary somatosensory
The posterior zone of the parietal cortex integrates ___ and ____ information for the control of movement.
somatic and visual
What is contralateral neglect syndrome?
inability to attend to objects or even one’s own body despite visual acuity, somatic sensation and motor ability remaining intact
What is ideomotor apraxia?
inability to copy movements when asked to do so
What is constructional apraxia?
spatial organization is disordered
What does the hippocampus function in?
declarative memory
What does the amygdala function in?
emotional processing and fear
What is the temporal cortex mostly?
unimodal- auditory and visual
What is associated with Wernicke’s area?
expressive aphasia
What is agnosia?
difficulties recognizing, identifying and name different categories of objects
What is the characterisitic of Broca’s aphasia?
people know what they want to say but they can’t get it out
Chronic drug use (cocaine) leads to diminished ___- activity in the PFC and _____ ____ cortex.
basal; anterior cingulate
What is the characteristic of the first four hours of sleep?
it is non-REM
What happens in Stage 1 of sleep?
you get drowsy; there is a decrease in frequency of EEG waves
What happens in Stage 2 of sleep?
it is a light sleep; there is a decrease frequency and intermittent spike clusters
what happens in Stage 3 of sleep?
this is moderate sleep; there is an increase in amplitude
What happens in Stage 4 of sleep?
it is deep sleep; low frequency and high amplitude delta waves
What is REM sleep characterized by?
decreased sensory input, decreased motor output
