When this potential passes a threshold value, the impulse is passed on. But below the threshold for a spike, a neuron’s action potential randomly fluctuates in a similar way to classical Brownian ...

In order for a neuron to transmit its own signal, it must first be sufficiently activated by incoming signals from other neurons via its dendrites. Then, an action potential is generated in its ...

Together with the artificial neural networks of McCulloch and Pitts ... including the shape and propagation of the action potential, its sharp threshold, refractory period, anode-break excitation ...

To that end, voltage imaging has the potential to combine the advantages of both of these techniques. Neuronal voltage “spikes,” or action potentials, in a mouse brain can be as short as a few ...

Our knowledge of the structure of voltage-dependent K + (Kv) channels, which shape the neuronal action potential, has come largely from studies of prokaryotic channels, which can be expressed at ...

Activating a protein called potassium channel Kv2.1 may help improve motor function in SMA, making it a potential SMA treatment target.
