Anatomy of Brain
A “net-like” system that separates the left and right hemispheres of the brain
Corpus callosum
Outer area of ear
The pleasure or “reward” neurotransmitter
Dopamine
Makes, stores, and releases hormones
Pituitary gland
Test that detects electrical activity in brain; a “shower-cap” like hat filled with electrodes
EEG (electroencephalogram)
Hemisphere of brain that is associated with creativity and making inferences
Right hemisphere
Made up of ganglion and bipolar cells entangled together, leaves eye through blind spot
Optic nerve
Excess dopamine causes this mental illness
Schizophrenia
Controls rest and digestion cycles after exercise/stimulation
Parasympathetic nervous system
Gives detailed image of soft tissues including brain, a magnetic scan
MRI (magnetic resonance imaging)
Part of brain that controls interpretation of language
Wernicke’s Area
When the lens changes it‘s curvature to focus on specific images
accommodation
Levels of dopamine that are too low cause
Parkinson’s
Communicates with internal organs and glands
Autonomic nervous system
Destroys tiny clusters of normal or defective cells
Leisoning
Area of brain that triggers fight or flight response
Amygdala
Bumps on tongue that contain taste buds
Papillae
Calms neural activity; an inhibitor
GABA
Processes sensory information between sensory and motor neurons
Interneurons
Shows each brain area’s consumption of glucose (depicts brain activity)
PET (positron emission tomography) scan
Filters incoming stimuli and arousal; a neuron network
Reticular formation
Gap that connects stapes to inner ear
Oval window
Antagonist for heroin
Narcan
Produces immune cells for the immune system
Thymus
Uses light to control activity of individual neurons (examines biological bases of fear, smell, etc.)
