"coup" vs "contrecoup" - "coup"= place where actual insult happens (ex: if something hits your forehead then part of the brain right there may show damage) "countrecoup"= opposite place of brain that can show damage even though actual insult didn't happen there because if something hit you then your brain can be stretched and moved around and hit other areas 10% of axons in the optic nerve go where - superior colliculus 5 basic tastes - salty, sweet, bitter, sour, umami a lesion ...

1. synthesis: - neurotransmitter manufactured in cell 2. storage: - neurotransmitter stored in vesicles for protection 3. release - action potential arriving at axon terminal will cause vesicles to move to membrane and release neurotransmitter into the synapse 4 key elements for electrical communication in neurons: - sodium, chloride, potassium, calcium - become charged when dissolved (NA+, K+, Cl-, Ca^2+) 4. receptor activation - neurotransmitters in the synapse can freely move about it. ...

A child at the zoo walks by the lion cage. The lion roars and the child cries, running to their mother. The next time the child sees the lion cage, she starts to cry and asks her mother to pick her up. (US, UR, CS, CR?) - US: Loud noise (roar sound; disturbing sound) UR: Crying CS: Lion cage CR: Crying After seeing an advertisement with a very attractive individual consuming an energy drink, Brian finds himself drawn to that same energy drink at the grocery store. (US, UR, CS, CR?) - US: ...

3 stages of object perception - early vision, mid-level vision, high-level vision absolute distance - you can tell how far away one object is accommodation and blur - intraocular cue as muscles adjust the shape of the lens atmospheric perspective - due to particles in the atmosphere, objects that are further away look less sharp and clear binocular depth cues - clues about distance based on the differing views of the two eyes binocular disparity - the difference in images for the two eyes ...

Can the complete process of photosynthesis take place in the dark? Explain your answer. - No because the plant will not have the light energy that is needed to carry out photosynthesis. Describe how breathing is controlled. - The force that drives air into the lungs comes from ordinary air pressure and is used to inflate the lungs along with the diaphragm. The air pressure is successful in doing this because the chest cavity is tightly sealed, which creates a partial vacuum inside the cavit...
