Can the dendrites of sensory neurons be a meter long?
The typical textbook structure of neurons is a cell with a short dendritic tree and a long axon. The dendrites receive information and send it to the axon via the cell body (soma). The axon is a long ...

Why can action potentials not be initiated at dendrites?
Why are action potentials not initiated at dendrites, although dendrites are the first to receive input from the presynaptic cell?
In fact, excitatory postsynaptic potentials (EPSPs) at the dendrites ...
