Document Summary

Resting potential of the neuron: concentration gradient - difference in concentration. Complexity of neurotransmitters complex functions and also interactions at different scales. Wetware allows brain to adjust itself to larger scale background conditions which neurons can be alters by complex feed back loops. Plaything of chemical gods" background conditions (want each to affect each other > neurotransmitters to affect background and background to affect neurotransmitters) background conditions can be internal and also external. Wetware with hardware and software allows brain to be much more sophisticated with dealing with external environment and internal (mixed system) Gaba: inhibitory, seizures, anxiety (anti anxiety meds help gaba bind more effectively to post synaptic receptors) Acetylcholine (ach): (peripheral nervous system vs. central nervous system) muscle/ motor vs. higher cognition (learning memory) [works differently in each system) plasticity, alzheimer"s. Epinephrine/ nor - e: arousal (energy not necessarily sexual) / alertness.
