Document Summary

Relook at appendix: statistical analysis p1000es@uwo. ca for secretary email early write, etc. Phineas gage severed the area between frontal lobe (judgments) and limbic system. Work on processes that terminate transmitter action. Dumps a lot of dopamine in synaptic cleft and then prevents re-uptake. Crack releases all dopamine in system and functions on reward pathway addiction. Does not allow movement (paralysis) consciousness. Stimulates receoptor molecules duplicating effect of ach. Adenosines makes one feel drowsy drowsiness is prevented. Depends on what happens at the other end. Epsps and ipsps are additive across space and time. Graded potentials, can add together or neutralize each other (i. e cancel each other out) Generation of ipsps constantly hyperpolarizes and makes gradient more negative. Ensure that it is more difficult to reach threshold. A single neuron might synapse with many others: Firing a weak neuron consecutively will/can generate a action potential. Firing two weak neurons (excitatory) together can generate a action potential.
