PPT-0 Neurons, Synapses, and Signaling

Which combination of axon features should lead an axon to communicate with downstream cells most slowly An axon that is 1 long 2 short 3 wide 4 thin 5 myelinated 6 nonmyelinated. IMPULSES SYNAPSES AND CIRCUITS A large part of neuroscience concerns the nut s and bolts of the s ubject how single cells work and how information is conveyed from cell to cell across synapses It should be obviou Charles Roddie.

This draft was first introduced in 2011 . We are increasingly seeing demand for this solution from the field for static PW deployments (more on this later). Understanding:. Neurons transmit electrical impulses. The myelination of nerve fibers allows for salutatory conduction. Neurons pump sodium and potassium ions across their membranes to generate a resting potential .
