OpticalStimulationDevice#

A Bonsai sink that wraps a dual-channel HS64 Optical Stimulator device.

Input:

A boolean that triggers stimulus delivery

OpticalStimulator.bonsai

Configuration#

Configuration is performed using either the property pane or a configuration GUI which provides a graphical representation of the stimulus waveform.

Parameters available through the property pane are as follows:

Name	Type	Description
Enable	boolean	Enable or disable the stimulator. If the stimulator is disabled, it will not respond to trigger inputs. This setting is useful if you wish to interleave electrical and optical stimuli, since they share a trigger line on some headstages.
MaxCurrent	double	Maximum current per channel per pulse (mA). This value is used by both channels. To get different amplitudes for each channel use the Channel0Level and Channel1Level parameters.
ChannelZeroCurrent	double	Channel 0 percent of max current. If greater than 0, channel 0 will respond to triggers.
ChannelOneCurrent	double	Channel 1 percent of max current. If greater than 0, channel 1 will respond to triggers.
PulseDuration	double	Pulse duration (msec).
PulsePeriod	double	Pulse period (msec).
BurstPulseCount	unit	Number of pulses to deliver in a burst.
InterBurstInterval	double	Interburst interval (msec).
TrainBurstCount	uint	Number of bursts to deliver in a train.
TrainDelay	double	Delay between issue of trigger and start of train (msec).

The configuration GUI is identical to the property pane, but provides a plot of the stimulus waveform.
