This Concept Map, created with IHMC CmapTools, has information related to: Electrical Properties of Neurons.cmap, Selective permeability that is largely due to ion channels dependent on conformational changes of the ion channels, Multiple Unit Recording: record action potential from many nearby neurons advantage? used for EEG recordings, Electrical Properties of Neurons is dependent on Resting Membrane Potential, Action Potentials Stages Neuron at rest, Resting Membrane Potential measured using Extracellular Unit Recording: record outside nearby neuron, Resting Membrane Potential can be calculate using <math xmlns="http://www.w3.org/1998/Math/MathML"> <mrow> <mtext> Nerst Equation
Ex=RT/xF * ln [X]o/[X]i
(looks at the concentration
of ONE ion) </mtext> </mrow> </math>, Electrical Properties of Neurons is dependent on Action Potentials, Electrical Properties of Neurons is dependent on Receptor Potentials, Resting Membrane Potential can be calculate using The Goldman-Katz Equation Vm= 58 log10 * (Pk[ion]o + Pna[ion]o +Pcl[ion]i) (Pk[ion]i + Pna[ion]i + Pcl[ion]o), Resting Membrane Potential dependent on K+ ion channels and concentration, Extracellular Unit Recording: record outside nearby neuron advantage? shows current fields and total activity, Concentration gradients that are set up by active transporters where? more K+ outside of the cell and more Na+ inside the cell, Resting Membrane Potential characterized by Selective permeability that is largely due to ion channels, Resting Membrane Potential measured using Multiple Unit Recording: record action potential from many nearby neurons, Intracellular Unit Recording: measure one cell's membran potential advantage? high resolution of electrical changes across membrane, Neuron at rest with input EPSP Excitatory Post-Synaptic Potential, Resting Membrane Potential characterized by Concentration gradients that are set up by active transporters, Electrical Properties of Neurons is dependent on Synaptic Potentials, EPSP Excitatory Post-Synaptic Potential Na+ influx Na+ channels open Depolarization, Resting Membrane Potential measured using Intracellular Unit Recording: measure one cell's membran potential
