This essay will describe the electrochemical processes that allow an Action potential to occur in a neuron. This will be achieved by firstly‚ defining the purpose of neurons in the body along with a description of the components within a neuron and how they enable information to be passed through the cell membrane and on to other neurons. Secondly‚ the resting potential of a neuron will be explored with relation to the concept of selective permeability and the purpose of the Sodium - Potassium

Neurophysiology Study Guide 1. Define "equilibrium potential". Why is the resting potential closer to the potassium equilibrium potential (EK+) than the sodium potential (ENa+)? The equilibrium potential is the point at which the force exerted on an ion by electrostatic and concentration gradient forces are balanced‚ and there is no net movement of that ion. The resting potential is closer to EK+ than ENa+ because the cell membrane is more permeable to

Materiality is a relative rather than an absolute concept. The materiality threshold that will influence users of the financial statements will vary depending on the context in which the entity operates. For example‚ the magnitude of a misstatement that will influence financial statement users will vary depending

This kind of behavior‚ called tonic spiking‚ can be observed in the three types of cortical neurons: regular spiking (RS) excitatory neurons‚ low-threshold spiking (LTS)‚ and fast spiking (FS)inhibitoryneurons[1]‚[6].Continuousfiringofsuchneurons indicate that there is a persistent input. B. Phasic Spiking A neuron may fire only a single spike at the onset of the input‚ as in Fig. 1(b)‚ and remain quiescent
