Overview of changes from StdpC 2012

  • m/h/tau HH currents received two new tau formulations:
    • "exp2/(1+exp1)": taum := taum0 + taumAmpl * exp((V-Vtaum)/staum) * minf
    • "Linear": taum = taum0 + taumAmpl * V, where the units of taumAmpl are interpreted as ms/mV in the interface, and s/mV in script/protocol values.
  • AEC is now associated with a specific analog input channel and is accessed through the input channel setup dialog. Consequently, there is no longer any restriction on the number of AEC channels. In addition, AEC computed currents can now be directed to a separate channel for data output purposes in addition to its usual function.
  • It is now possible to use several data sources (DAQs, files, spike generators, models) simultaneously.
  • There is now an option to simulate entire (single-compartment) Hodgkin-Huxley neurons, see section 7.4.6 (Hodgkin-Huxley model neurons) in the manual.
  • It is now possible to define an arbitrary number of HH conductances and synapses.
  • Currents and synapses can now be assigned to more than one set of channels. Each assignment draws on the common parameter set, but is functionally independent from other assignments.
  • As a consequence of changed protocol conventions, channel assignments in protocols written for/by older StdpC versions may be wrongly converted. Please check for correctness and/or update your protocols.
  • Synapses (but not gap junctions) now support conduction delays.
  • Currents, synapses, channel assignments, neuron models and model instances can now all be turned on or off by script while the clamp cycle is running using the active parameter, provided that they were active when the clamp cycle was started.
  • The graph system has been overhauled, providing much better performance and handling than previously.
  • A performance indicator has been added to the main window showing the actual clamp cycle frequency.
  • Large parts of the code have been cleaned up and refactored/rewritten into a more modular design.
  • The manual has been updated to reflect the new features and changed interface.
