These reactions lead to a change in cellular electrical charge, which generates a nerve impulse.
This receptor potential, on reaching sufficient (threshold) strength, acts to generate a nerve impulse within the corpuscle.
Because this hyperpolarization draws the membrane potential farther from the threshold, making it more difficult to generate a nerve impulse, it is called an inhibitory postsynaptic potential (IPSP).
The sudden shift from a resting to an active state, when the neuron generates a nerve impulse, is caused by a sudden movement of ions across the membrane specifically, a flux of Na+ into the cell.
This is the membrane potential of the neuron at rest (i.e., when it is not generating a nerve impulse), and for this reason it is called the resting potential.
That triggers a biochemical cascade, ultimately generating a nerve impulse that transmits information about smell to the brain.
The axons of these two functionally distinct types of neurons are entangled, generating a single nerve.
As shown in Fig. 1B, a dose-dependent increase in nerve firing was found when H2O2 was applied extravesically under isovolumetric conditions (15 mmHg); however, only the highest concentration of H2O2 generated a statistical significant increase in nerve activity (one-way ANOVA, Dunnet's post hoc test, * P < 0.05).
Yesterday, a team from Harvard and Columbia universities announced that they have generated a population of motor neurons--nerve cells that control muscle movement--from the skin cells of an 82-year-old woman with amyotrophic lateral sclerosis (ALS).
Various combinations of NTs, neuropoietic cytokines and GFLs have been shown to generate a microenvironment suitable to improve nerve repair [ 26].
Thirty-four years later May-Britt and Edvard Moser, of the Norwegian University of Science and Technology in Trondheim, identified another type of nerve cell that generates a co-ordinate system for precise path-finding, the assembly said.
