- Gee, I don't recall ever reading that dendrites and axons use "zero or
- one" action potentials. Most of what I've studied led me to believe
- that "dendritic computation" was characterized by continuous
- quantities of of membrane potentials. A good deal of the neural
- modelling I've read attempts to model and explain the rich behavior of
- dendritic membranes.
-
- Perhaps I've missed something. Could someone direct me to the proper
- references where the "zero or one" action potential is claimed for
- dendrites? I am, of couse, aware of spike potentials and the like,
- but have never viewed the neuron as a logic gate where the sole unit
- of information is the spike potential. I always viewed information
- transfer in the nevous system as being slightly more complex.
