An electronic implementation of the neuron is also considered.
"The neuron is a good analog in some ways," Noy says of these devices.
Smaller values of λ suggest that the neuron is more sensory (visual in our case) and larger values of λ signify that the neuron is closer to the motor output.
From the spines to the soma, signal processing in the neuron is intrinsically nonlinear.
"The neuron is not building the 'gun' as it sits there on the membrane – it's already there," Brunger said.
First, a structural description of the neuron is built, including the topology and the exact dendritic lengths and diameters.
The neuron is either at rest with a polarized membrane, or it is conducting a nerve impulse at reverse polarization.
The plasma membrane of the neuron is semipermeable, being highly permeable to K+ and slightly permeable to Cl− and Na+.
We identify a low dimensional subspace of signals within which the neuron is most sensitive, and then sample this subspace to visualize the nonlinear structure of the mapping.
The bursting arises as the fast-spiking behavior of the neuron is modulated by the slow oscillatory behavior in the ion concentration variables and vice versa.
Of course, neuroscientists want to know not just where the neurons are, they also want to see if the neuron is active.
