Sleep
responsible for regulating circadian rhythms
Superchiasmatic nucleus (hypothalamus)
drugs that inhibit the CNS and thus slows physical and mental activity
depressant
Located at the bottom rear of the brain. Looks like a smaller version of our brain stuck onto the underside of the brain. Coordinates some habitual muscle movements, such as tracking a target with our eyes
Cerebellum
your brain's way of adapting or producing neural pathways
neural plasticity
deepest point in sleep cycle; when brain waves are the slowest
REM (Stage 4)
drugs that suppress physical sensation and response to stimulation, including pain
opiates
Located at the top of the brain stem. Responsible for receiving the sensory signals coming up the spinal cord and sending them to the appropriate areas in the rest of the forebrain.
thalamus
Located in the frontal lobe and responsible for controlling the muscles involved in producing speech. Damage to this area might leave us unable to make the muscle movements needed for speech.
Broca's area
time it takes to experience I sleep cycle
90 mins
drugs that alter perception of the external environment and inner awareness
hallucinogens
Vital to our memory system. Located in the limbic system. Memories are not permanently stored in this area of the brain, however. Memories are processed through this area and then sent to other locations in the cerebral cortex for permanent storage
Hippocampus
Located in the left temporal lobe. Interprets both written and spoken speech. Damage to this area would affect our ability to understand language
Wernicke's area
according to freud, this refers to the storyline of the dream; what we remember of the dream
manifest content
drugs that arouse the CNS, speeding up mental and physical processes
stimulants
Nerve bundle that connects the two brain hemispheres.
Corpus callosum
part of the brain triggers the release of adrenaline to boost heart rate when you’re afraid
hypothalamus
this happens the night after a night of REM deprivation
REM rebound
most widely used addictive legal drug; increases heart rate, circulation and signaling to the brain
caffeine
Located just above the medulla and toward the front. Connects the hindbrain with the midbrain and forebrain. Involved in sleep regulation.
pons
In each eye, information from the left visual field goes to your ____ hemisphere, and information from the right half of your visual field goes to your ___ hemisphere
right; left
