neuropsych Flashcards
what is the sagittal cut of the brain?
the cut is seperates the lobes into two hemispheres
what is the coronal cut of the brain?
is a medial cut so it is down the middle of the brain
what is the horizontal cut of the brain?
the brain is cut horizontally
what is the cerebrum?
it is the entirity of the brain and includes all of the sections (hemipsheres, lobes)
what joins the left and right hemisphere?
corpus callosum
what is it called with the brain is folded into ridges?
gryi
What are the shallow grooved formed by gyri between them called?
sulci
what are the four lobes of the brain?
occipital, parietal, frontal, temporal
where is the frontal lobe located and what is its function?
far most anterior part of the cerebrum?
helps with motor function, problem solving, memory, language, judgement, social and sexual behaviour, impulse control. it is used for higher cognitive functioning
what is the function of the temporal lobe and what is it function?
lies beneath the parietal lobe and behind the front lobe
functions as the auditory processing section, language and autobiographical memory
what is the function of the parietal lobe and what is its function?
behind the frontal lobe and above the occipital lobe
touch, pain, proprioception, (where our body is), pressure, temp, taste
- contains the primary somatosensory cortex
what is the occipital lobe function and where is it located
the most posterior part of the cerebrum
it helps with visual perception
what is the central sulcus?
seperates the frontal and parital lobes and contains the primary motor cortex and primary somatosensory cortex
what is grey matter of the brain or the brain cells?
gryi
what is the connection between cells?
white matter
what does the primary somatosensory cortex do?
responsible for proprioception, and somatic sensations such as touch, pressure, temp and pain
is the motor cortex behind or infront of the central sulcus?
infront and the somatosensory cortex is behind
what does the primary motor cortex do?
it is the main communication intersection for voluntary motor movement
what is the function of the broca’s area?
language production
what is Wernicke’s area responsible for?
interprets spoken and written language
what does the prefrontal cortex do?
it decided on reactions to current events based on past experiences and societal rules
the amount of brain matter devoted to a body part representing the amount of control the primary motor cortex has over that part of the body is called?
motor homunculus
the amount of cortex attributed to a body part is proprotions to its sensitivity, is called?
sensory homunculus
where is the cerebellum and what is its function?
most posterior and closest to the bottom of the brain.
it helps to control and coordinate movements, balance and learn motor skills
what is the function of the brain stem and what does it contain?
midbrain, pons and medulla
performs functions that keep us alive
helps with physiological states like hunger and thirst
what is the function of the mibrain?
plays a role in movement, controls the tracking of visual stimuli and controls sound reflexes
what is the function of the pons?
triggers dreams and connect the cortex to the cerebellum
what is the function of the medulla?
regulates heartbeat, breathing and other vital functions. also controls nausea and vomiting
serious damage can cause brain death
what is the function of the hypothalamus?
regulates emotions, hunger, thirst, sex drive, fear and anger
what does damage to the Broca’s region of the brain cause? Broca’s aphasia?
they can understand speech but they cannot produce coherent sentences
what does damage to the Wernicke’s area cause? Wernicke’s aphasia
they cannot understand speech but they can speak in coherent sentences.
what is hemianopia?
spatial neglect, only register half the world (i.e. only see the right side)
