This is where you put a short paragraph to introduce the salient features of this neuron. What should everyone know about this cell if they don't read any farther.


This is where you put information related to the anatomy of the neuron.

  • Cell body location:

    • Anterior connective
    • Posterior connective
    • Ganglion root
    • Ipsilateral/Contralateral


Spiking properties

Synaptic Connections

Synaptic Inputs

Synaptic Outputs

  • N cells make excitatory synapses on the AE cell. Work by students in the NS&B course in 2008 suggests that not all N cells have equivalent synaptic strength on AE.
