Unit two test Flashcards
does alcohol affect inhibition- what is inhibition?
Drinking can lower your inhibitions.
Alcohol depresses the cerebral cortex of the brain, which slows down the way your senses process information. This will decrease your inhibitions, and also make it difficult to think clearly.
what part of brain is affected by aphasia?
frontal lobe
What is stereotaxic examination?
Stereotaxy is a minimally invasive brain surgery, performed using a three-dimensional system allowing precise placement of a cannula, an electrode, or a probe into a small area of the brain
what is computerized axial tomography
a form of tomography in which a computer controls the motion of the X-ray source and detectors, processes the data, and produces the image. CT scans are used to evaluate most medical problems.
what do antidepressants do?
produce more neurotransmitters like serotonin.
which part of the brain controls breathing?
Medulla
what is the autonomic nervous system?
a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal
damage to which part of the brain causes a coma?
Coma occurs when there is a serious problem with the brain’s arousal system (the reticular activating system), or with its communications between other brain areas (such as the cerebral hemispheres) and the brain’s activity becomes impaired.
what is brain lateralization?
the limitation of a bodily function, such as speech or handedness, to one side of the brain.
what monitors the brain at work through metabolism of glucose?
PET scanner
what is the fear response part of the brain?
amygdala
which part of the brain is affected by amnesia?
Amnesia can result from damage to brain structures that form the limbic system. the amygdala, hippocampus, thalamus, hypothalamus, basal ganglia, and cingulate gyrus
cocaine blocks the reuptake of what?
Cocaine inhibits the re-uptake of synaptic dopamine and serotonin, as well as norepinephrine
what is manifest vs latent content?
The manifest content is the actual dream content remembered the following day. The latent content of dreams pertains to unconscious wants, fears, or desires.
what is the occipital lobe?
responsible for visual perception, including colour, form and motion.
what is the cerebellums function?
The cerebellum is primarily responsible for muscle control, including balance and movement
what controls voluntary muscle movement?
somatic nervous system
what is EEG?
a test that measures electrical activity in the brain using small, metal discs (electrodes) attached to the scalp. Brain cells communicate via electrical impulses and are active all the time, even during asleep. This activity shows up as wavy lines on an EEG recording.
what are pineal glands?
receive information about the state of the light-dark cycle from the environment and convey this information by the production and secretion of the hormone melatonin
what are adrenal glands?
produce hormones that help regulate your metabolism, immune system, blood pressure, response to stress and other essential functions
what is norepinephrine?
Norepinephrine is part of your sympathetic nervous system, which is part of your body’s emergency response system to danger — the “fight-or-flight” response.
what are amphetamines used to treat?
people with ADHD or narcolepsy
what is the pituitary gland?
a small, pea-sized endocrine gland located at the base of your brain below your hypothalamus. It releases several important hormones and controls the function of many other endocrine system glands
what is the cerebellum?
a part of your brain located at the back of your head, just above and behind where your spinal cord connects to your brain itself. The name “cerebellum” comes from Latin and means “little brain.” For centuries, scientists believed your cerebellum’s job was to coordinate your muscle movements
What is an MRI?
Magnetic resonance imaging (MRI) is a medical imaging technique that uses a magnetic field and computer-generated radio waves to create detailed images of the organs and tissues in your body.
What is neuroplasticity?
the ability of the brain to form and reorganize synaptic connections, especially in response to learning or experience or following injury.
What is the amygdala?
responsible for the perception of emotions such as anger, fear, and sadness, as well as the controlling of aggression
