After RF ablation, the cell membrane is damaged and is unable to maintain the resting potential, which is the ability to hyperpolarize the cell membrane compared to the extracellular space.
In the hippocampus and the prefrontal cortex, for example, this potentiation and subsequent binding of GABA hyperpolarizes the cell making the release of acetylcholine less likely.
At some synapses, he found, an impulse hyperpolarizes the post-synaptic membrane, thereby making it more difficult to trigger a successive impulse.
Indeed, V-opioid receptor activation hyperpolarizes (i.
2+] exposure alters two membrane conductances in the root membranes of both species of Arabidopsis, a rapidly initiating conductance change that hyperpolarizes the membrane and a more slowly initating change that depolarizes the membrane.
The calcium-activated potassium current hyperpolarizes the neuron, which results in a pause after the burst of action potentials.
The PIA sends projections to NGC (74), NMC (71,75) and NPM (76) of the medullary region, which in turn project to the spinal cord (72,75,77) to hyperpolarize motoneurons to control the spinal circuits for inducing atonia during REM sleep (78,79).
During an action potential, the plasma membrane depolarizes to approximately 0 V and the vacuolar membrane hyperpolarizes to approximately -0.
The membrane potential of the vacuolar membrane hyperpolarizes from -0.
