the part of the brain at the back of the skull in vertebrates. Its function is to coordinate and regulate muscular activity.
What is the cerebellum?
a chemical substance that is released at the end of a nerve fiber by the arrival of a nerve impulse and, by diffusing across the synapse or junction, causes the transfer of the impulse to another nerve fiber, a muscle fiber, or some other structure.
What is a neurotransmitter
responsible for color vision.
What are cones?
when a bump, blow, jolt, or other head injury causes damage to the brain
What is a traumatic brain injury?
a kind of sleep that occurs at intervals during the night and is characterized by rapid eye movements, more dreaming and bodily movement, and faster pulse and breathing.
What is REM sleep?
each of the paired lobes of the brain lying immediately behind the forehead, including areas concerned with behavior, learning, personality, and voluntary movement.
What is the frontal lobe?
may result in depression.
What results in serotonin deficiency?
visual processing center of the brain
What is the occipital lobe?
loss of consciousness and violent muscle contractions
What is a grand mal seizure?
a high amplitude brain wave with a frequency of oscillation between 0.5–4 hertz, usually associated with the deep stage 3 of NREM sleep
What are delta waves?
Right and left hemispheres
What are the two halves of the cerebrum/brain?
found between the nerve synapses, or gaps, between nerve cells. When activated, it causes the contraction of skeletal muscles and activates glandular functions in the endocrine system.
What is acetylcholine?
figures out the messages you receive from the five senses of sight, touch, smell, hearing and taste.
What is the parietal lobe?
a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining 12 years of his life
Who is Phineas Gage?
the last 10 minutes of a cycle, gets longer each iteration
How long does REM sleep last?
the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement.
What is the cerebrum?
may result in Parkinson's.
What is a result of dopamine deficiency?
the spiral cavity of the inner ear, which produces nerve impulses in response to sound vibrations.
What is the cochlea?
occurs at the cellular level. It is most often associated with pressure on the brain. This could come from a tumor. Or it could result from neurological illness, as in the case of a stroke.
What is an acquired brain injury?
90-120 minutes
How long is a sleep cycle?
The surface of the cerebrum
increase the likelihood that the neuron will fire a signal called an action potential in the receiving neuron.
What is an excitatory neurotransmitter?
sight, sound, taste, touch
Which senses does the thalamus control?
a pooling of blood in the tissues outside of the blood vessels
What is a hematoma?
thought to serve as protection for the brain from awakening from sleep
What are sleep spindles and K complexes?
