The speed at which and Action Potential (AP) occurs, resting membrane potential, and threshold to AP all vary across types of neutron. See the graph below (Bean, 2007) The reasons for these differences are various, as you will see if you read the referenced article, which I highly recommend as everything I write from here is based upon it.

It also measures the amplitude in volts of each action potential or an extracellular field potential. The amplitude is a relative measure that can be used to determine if different size of extracellular recorded action potentials are present. An action potential recorded by an extracellular field potential.

Jul 18, 2018  · Pretty much what Carl said, to elaborate why it’s -70mV and not -20 or -100 is due to the amount of charged Potassium ions (K+) and charged Sodium ions (Na+) within the membrane, there are more K+ than Na+ inside the membrane (Na+ has a stronger c.

Cell-attached recording is extensively used to study the firing rate of mammalian neurons, but potential limitations of the method have not been investigated in detail. Here we perform cell-attached recording of molecular layer interneurons in cerebellar slices from rats and mice, and we study how experimental conditions influence the measured firing rate.

When the molecular signal binds to the receptor, the cell membrane of the target neuron changes its electrical state and a new graded potential begins. If that graded potential is strong enough to reach threshold, the second neuron generates an action potential at its axon hillock.

Oscillatory activity can also be observed in the form of subthreshold membrane potential oscillations (i.e. in the absence of action potentials). If numerous neurons spike in synchrony, they can give rise to oscillations in local field potentials. Quantitative models can estimate the strength of neural oscillations in recorded data.
