So coming back to the question of understanding the physiological parameters and their attribution being measured, the nerve cells regarding the CNS and the brain exist in a polarised state between -70m.V. and -110m.V. with an exact cell potential within the range showing the cell to be vulnerable to the stimulus that would give an outcome of regenerative breakdown. All cells within a formation rest at a normal polarised level of -90m.V. For example; if one cell was to depolarise from an external stimulus, the depolarisation will begin to affect the adjoining cells next to it causing a synapses between cells resulting in a change of the resting potential. If the resting potential is increased, a breakdown of the cell membrane will not occur and the impulse can be defined as taking an inhibitory effect. If the impulse arriving at the synapses reduces the resting potential, then this allows the cell to be more vulnerable of depolarisation and the impulse will have an excitatory effect on the
