Document Summary

Human brian - lecture 4 relatively positively electric charge caused by. Pre synaptic / post synaptic side > junction in between is the synaptic cleft. Micheal j fox/parkinson"s > not enough dopamine: drugs tat stimulate da release > addictive schizo > too much dopamine. Mimicker > chemicals that can mimic the activity of a neurotransmitter: activates the receptor. One way to incr the activity of a sys is to increase the synthesis of the system. Blocker looks enough like a transmitter itself so it can fit in perfectly into the receptor but does not activator. By decreasing inactivation you are actually increasing activation: by increasing inactivation > you are decreasing activation. Catecohlamines: dopamine [da, norepinephrine [ne/na] they are synthesized by tyrosine > dopa > da > ne > e to treat mjf we use dopa [l dopa pill everyday, text: epinephrine [e] Adrengenic recptors > metabotropic, mediate hormonal effects.
