Document Summary

Office hours- mondays and wednesday 3-4 slightly different next week. The neuron and networks of neuronal connections. Alterations in a neuron"s resting potential are the basis for all cell communication. Always measure inside with respect to the outside (inside - outside = negative potential) Selective membrane permeability and ion flow (na, k, cl-) Charges accumulate or lose across a membrane then the voltage will increase or decrease. The gradient will go from high to low: will be pushed for chemical gradient. Electro static force: from an electric point, a positive wants to be a negative. Salty fluids on both sides of membranes (sodium chloride- dissolves into ions) Ions are atoms that have gained or lost electrons (charged over time q/t=i (current)) Voltmeter will measure the voltage across the membrane. Voltages created when ions flow and separate chargers in space. Measure the voltage between a and be which is the resting potential. Measured with respect to 2 points uv to mv.
