Overview
  • Title: Simulation Movie
  • Description: The movie shows a model globus pallidus neuron being driven to spike by synaptic inputs. There are 100 excitatory inputs (represented as spheres on the dendrites) and 1024 inhibitory inputs (not shown), each activated randomly. Excitatory synapses activate when their color changes from red to white. The membrane potential of each compartment is presented in pseudocolor, showing that action potentials initiate in distal dendritic compartments and propagate to all regions of the model neuron. Near the end of the movie (approximately 94 msec on the simulation timer), a spike initiates in a thin dendrite but fails to propagate past the first branch point it reaches, suggesting that branchpoint failures may be important components of dendritic integration in the model.
