Parts of the Brain
What is the hindbrain's location and main (2) functions?
Location: lower and back part of the brain
1) life support
2) connects brain and spinal cord
The word that refers to a brain's ability to CHANGE throughout one's life
What is neuroplasticity or brain plasticity
What are motor neurons?
What are the chemicals used by a neuron to transmit messages across the synapse called?
Neurotransmitters
In tonotopic organization where do low frequencies and high frequencies respond better?
Apex responds best to low frequencies
Base responds best to high frequencies
"relay station"--> coordinates sensory information
The part of the brain (not lobe) that is responsible for conscious activities, intelligence, learning and judgement?
What part of a neuron is information processed?
The soma
The part of the eye that receives light and converts it into a neural signal
The retina
What is the number of repeating cycles per second?
(how packed vibrations are over time
What is the forebrain's main function?
The part of the brain (not lobe) that coordinates and balances actions of muscles
What is cerebellum?
What is the space between the axon terminal and dendrite of a neighboring neuron called?
Synapse or synaptic cleft
Peripheral vision has more _____ than ________
rods than cones
What is the difference in pressure, between high and low peaks called? (size of pressure changes)
What is amplitude?
The lobe that is responsible for auditory processing, speech, language comprehension?
AND on what hemisphere?
Temporal, left
Controls heart rate, blood pressure and breathing
Brain stem
Where are neurotransmitters released?
Synapse or synaptic cleft
The stimulus for vision
Light
Macular degeneration destroys the _______ creating another "blind spot" on the ________
Fovea, retina
The lobe that is responsible for processing sensations of touch, temperature and pain
What is parietal
The part of the brain (not lobe) that receives messages and relays information to other parts of the brain
Thalamus and hypothalamus
What is the difference in electric potential between the interior and exterior of a biological cell (e.g. neuron) called?
Membrane potential (mV)
What is myopia?
What type of lens corrects myopia?
Nearsightedness- occurs when the eyeball is too long or curvature of the cornea is too steep
Correction: Concave lenses
What is hyperopia?
What lens corrects hyperopia?
Farsightedness- caused when the eye is too short or curvature of the cornea is too flat
Correction: Is a convex lens (a wider more curved lens brings the focal point closer to the lens)
