What does BHM stand for? What does BHM mean? This page is about the various possible meanings of the acronym, abbreviation, shorthand or slang term: BHM.
If a neuron receives a series of stimuli whose effect is excitatory but subthreshold the neuron is more excitable to incoming stimulation than before and is said to be facilitated Transmitting a nerve impulse from one neuron to another involves a nerve impulse stimulating a presynaptic axon to release a neurotransmitter into a synaptic cleft Action potential related to nerve impulses in that
Excitability is thus described in terms of the qualitatively different transitions neurons exhibit as they go from resting to spiking states. Underlying a neuronâs excitability is a host of ion channels that allow sodium, potassium, calcium, etc. to go in and out of the cell.There is a relationship between the types of rest-to-spiking transitions neurons can make and the type and number of ion channels they express (see for example pdf).Working in model systems like Drosophila, we can change the levels of channel expression in neurons and see how their excitability changes.urthermore, we can target these manipulations to groups of cells, like motor neurons, to ask how changing their excitability affects motor behaviors. Below is an example of a genetic manipulation of potassium currents in Drosophila motor neurons (article available here) that Iâve used in my work (unpublished to date).
