The action potential of the squid giant axon is formed by just two voltage-dependent conductances in the cell membrane, yet mammalian central neurons typically express more than a dozen different types of voltage-dependent ion channels. This rich repertoire of channels allows neurons to encode infor...
The single action potential of a nerve message to a muscle is called. ___ Motor Neurons Control the Contraction of Muscle Fibers A motor unit is one motor neuron and the muscle fibers it controls. A motor neuron ends in synaptic terminals that are in close proximity to the mo...
Where, and how, in the neuron does a local potential activate an action potential? What kind of action potentials are sent from the muscles to the brain? What must be "met" in order for a neuron to initiate an action potential?
Unique features of action potential initiation in cortical neurons. Neurons process and encode information by generating sequences of action potentials. For all spiking neurons, the encoding of single-neuron computations in... B Naundorf,F Wolf,M Volgushev - 《Nature》 被引量: 472发表: 2006年 ...
Resting potentialThe average resting potential of a plant cell membrane also differs from that of a neuron. For example, the Venus flytrap cell rests on average at approximately − 120 mV (in contrast to the average − 60 mV to − 70 mV of animal APs), eliciting an AP at the thre...
Recently, experiments using simultaneous patch-pipette recordings from different locations on the same neuron have been used to address this issue directly. These studies show that the site of action potential initiation is in the axon, even when synaptic activation is powerful enough to elicit ...
Innate behaviors meet multiple needs adaptively and in a serial order, suggesting the existence of a hitherto elusive brain dynamics that brings together representations of upcoming behaviors during their selection. Here we show that during behavioral transitions, possible upcoming behaviors are encoded by...
At rest, the Vm of a neuron is around -70 mV (close to the equilibrium potential for potassium, VK), but during an action potential, Vm transiently approaches +50 mV (close to the equilibrium potential for sodium, VNa). The membrane potential then rapidly returns to the resting potential ...
