a communication system to send TTLs pulses to an external device (such as a electrophysiological Input board). These electric signals are synchronous with the events that we manage on our software. In this way, all the events (anilal behavior as well as activation of actuators) will be signed on your electrophysiological trace.
a rotation and rearing compensator, compatible with any optical commutator,
a device to activate lasers. This accessory sends electric signals up to 500Hz. The experimenter decides the exact moment according to clocks or behavioral outputs at which a customized train of pulses may be sent to the laser to specifically activate the targeted bunch of neurons.
