This Concept Map, created with IHMC CmapTools, has information related to: Electrical Properties of Neurons Final, Resting Membrane Potential characterized by Concentration gradients that are set up by active transporters, Resting Membrane Potential can be calculated 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>, Voltage gated K+ channels TEA Toxin that blocks K+ channels and shows Na+ early current, Slow-opening and long opening contributes to Relative Refractory period, Voltage gated Na+ channels is regulated by membrane protiens, Electrical Properties of Neurons is dependent on Receptor Potentials, Voltage gated Na+ channels TTX Blocks Na+ channels and shows K+ late current, Electrical Properties of Neurons is dependent on Resting Membrane Potential, Electrical Properties of Neurons is dependent on Action Potentials, Resting Membrane Potential characterized by Selective permeability that is largely due to ion channels, Synaptic Potentials affected by lamda Spatial summation: synaptic potentials generated in different regions of the neuron are added together, Extracellular Unit Recording: record outside nearby neuron advantage? shows current fields and total activity, Electrical Properties of Neurons is dependent on Synaptic Potentials, Voltage gated K+ channels regulated by membrane protiens, Neuron at rest with input EPSP Excitatory Post-Synaptic Potential, membrane protiens inactivation H-GATE, Resting Membrane Potential can be calculated 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), Intracellular Unit Recording: measure one cell's membran potential advantage? high resolution of electrical changes across membrane, Receptor Potentials Voltage gated K+ channels, Synaptic Potentials affected by Tau Temporal summation: synaptic potentials generated in the same membrane patch as a result of successive stimulaiton are added together
