3 monomaines
dopamine, norepinephrine, serotonin DNS
voluntary movement, emotions, Park and Schizo variations
DA dopamine
mood & arousal, depression
norephphrine NE
serotonin
sleep wake cycle, wakefulness, eating, aggresion, ab levels: depression, OCD, SSI's work here
endorphins
resemble opiate drugs in structure and effects, pain and relief in some aspects
Ach
Acetylcholine: skeletal muscles, MEMORY, attention and arousal
CT
a computer is used to construct images of the brain (or other parts of the body) from a series of x-ray scans
MRI
uses magnetic fields, radio waves and computerized enhancement to map out brain structures
EEG
method that amplifies these patterns and records them as distinctive signatures on an electroencephalogram
fMRI
visualize the activity in its various regions
PET
used to show how brain and behavior are related uses radioactive markers to map chemical activity in the brain over time
cerebrum
sensing, thinking, learning emotions, consciousness and voluntary movements
pons
sleep, arousal, bridge of fibers that connects the brain with the cerebellum
medulla
unconcious
amygdala
part of limbic system involved in agression, emotion and fear
reticular formation
modulation of muscle reflexes, breathing and pain perception
forebrain
includes thalamus, hypothalamus system, cerebrum
spinal cord
simple reflexes
hippocampus
learning and memory
pituary gland
master gland that regulates other glands in the endocrine system
thalamus
handles everything except smell incoming and outgoing

genes
DNA segments that serve as the key functional units in hereditary transmission
chromosomes
threadlike strands of DNA
split brain surgery
bundle of fibers that connect the cerebral hemisphere is cut to reduce the severity of epileptic seizures
wernicke s
comprehension of speech areas
OPFT
order of the lobes in the brain O at the bottom P and F at top with temporal (hearing) at bottoms..
as myelin shealth deteroriates
the transmission of the signal runs slower
chemicals serve as messengers that may activate neighboring neurons
terminal buttons
info is received at the dendrites, passed through the soma to dendrites of other cells
called synapses, meeting point
