Document Summary
4, 5 (neuron to brain 5th ed. : know all info in text related to figures used, know all info that relates to class material, olfactory bulb has direct connection to hippocampus. Info comes in thru sensory recs via sensory systems, certain circuits: cognitive input thru higher centres, brain makes decision carried out thru pns causes internal change in smooth or skeletal muscle. In order to have act pot, need membrane pot (needs dif in electrical charge btwn inside & outside of cell: built up thru prot gradients at neurons. Ion channels contribute to generate membrane pots when opened, help generate act pots. Ions cannot directly pass thru, must move thru prots: channels = membrane spanning; don"t use atp, when opened ion goes thru down electrochemical gradient, would run these gradients gown if always open, so use transporters (ex. Atpase) to move ions against conc grad establish ion gradient (so when channels opened, ions can move down grad)
