How do we study brain - function relations? By using different types of scans, PET CAT
What are neural networks? When neurons cluster in groups
For each structure know its location and primary functions
Brainstem- control’s heart beat and breathing SEE PICTURE
Hypothalamus- controls hunger, thirst, sex drive. Center of brain SEE PICTURE
Thalamus- Controls the body’s senses. Located above the Hypothalamus
Cerebellum- lower back part of spinal cord. Judge time, modulate our emotions, and
discriminate sounds and textures
Limbic system- hypothalamus, pituitary gland, amygdale, hippocampus
Corpus callosum- the large band of neural fibers connecting the two brain hemispheres
and carrying messages between them.
Hippocampus- a neural center that is located in the limbic system and helps process
explicit memories for storage
Amygdala- two lima bean-sized neural clusters that are components of the limbic
system and are linked to emotion.
Frontal lobe- the portion of the cerebral cortex lying just behind the forehead; involved in
speaking and muscle movements and in making plans and judgments.
Parietal- the portion of the cerebral cortex lying at the top of the head and toward the
rear; receives sensory input for touch and body position.
Temporal- the portion of the cerebral cortex lying roughly above the ears; includes the
auditory areas, each receiving information primarily from the opposite ear.
Occipital lobes- the portion of the cerebral cortex lying at the back of the head; includes
the visual areas, each receiving information from the opposite visual field.
Visual cortex- receives written words information as visual. Lower back brain
Auditory cortex- transforms visual in to written. In front of the visual
Motor cortex- Words are pronounces. Sliver up the middle brain
Sensory cortex (homunculus)- processes body sensations frontal lobe
Left hemisphere- speaks or calculates, activity increases
task, for example, brain waves, bloodflow, and glucose
Contralateral control- the example of the guy who’s brain wasn’t connected.
Split brain research - be able to predict results if given specifics of task
Brain plasticity- the brain's capacity for modification, as evident in brain reorganization
following damage (especially in children) and in experiments on the effects of
experience on brain development.
What is consciousness? Being in an altered state of mind.
What are altered states of consciousness? Types of personality disorders,
Daydreaming, sleeping, drug induced, meditative, hypnosis, near-death experiences
What are circadian rhythms s: biological clock; cyclical body rhythms, 25 hour cycle, 9-
10 hours is best for most people-should wake up feeling rested
Sleep deprivations- difficulty studying, diminished productivity, tendency to make
mistakes, irritability, and fatigue
