TBL 5 Flashcards
Does damage to UMNs affect proximal or distal muscles more?
Distal
Through what tract does taste info travel to thalamus?
Where does it project to in cortex?
Solitariothalamic tract (STT) Insular cortex.
Bradyphrenia
Slow mentation (slow thinking)
Delusion
Fixed, false belief that is unusual for that culture
What areas of brain are important for focus / attention
PFC and cingulate cortex
Damage to what area causes hemineglect
Nondominant parietal association cortex
Dysphagia
Partial deficit of language
Paraphasia
Word error. May have similar sound, such as “block” instead of “clock”, similar meaning, such as “watch” instead of “clock”, or may be nonsense, such as “brop”.
Anomia
Abnormal naming
Receptive aphasia
Normal fluency but words are nonsense
Damage to arcuate fasciculus causes what?
Conduction aphasia. Problems w/ repetition.
Prosody
Emotional context / inflection of speech. Controlled by nondominant hemisphere.
Expressive aprosodia caused by what?
Due to anterior lesion on non dominant side.
Receptive aprosodia caused by what?
Due to posterior lesion on non dominant side.
Limbic areas include: (7 things)
Cingulate, orbital, and medial PFC, nucleus accumbens (ventral part of basal ganglia), hippocampus, amygdala, and hypothalamus
What is abulia? What causes it?
Deficit of motivation. Due to damage of anterior cingulate cortex.
What NT does basal forebrain release for arousal?
Ach
What NT does hypothalamus release for arousal?
Histamine
What NT does locus coeruleus release for arousal?
NE
What NT does ventral tegmentum release?
DA
What NT does raphe nuclei release for arousal?
Serotonin
What areas does anterior choroidal artery supply?
Subcortical areas, such as thalamus and internal capsule. NOT cortex.
