Default settings that can be controlled by the Preferences menu include sign of current, default settings for initial values and different methods to select subranges of campartments in large neuron models. The value of any simulation database parameter can be manipulated by the user during simulations. Up to 24 variables can be plotted on 4 axes. On screen measurement of plotted results is possible. One can voltage clamp two neurons simultaneously, with superposition of traces.
Synapses can be preset to fire at specified times or to fire stochastically.
Ionic currents can be blocked selectively during simulations. Synaptic plasticity will become available in future releases. Neurons can have up to 4000 compartments. Membrane resistance and conductance can vary between compartments. Compartments can be split or fused manually or automatically to keep their electrotonic length within user defined bounds.
