DALLAS, TEXAS — (September 17, 2014) – Plexon Inc, the leader in advanced hardware and software solutions for neuroscience and behavioral research, is pleased to announce that PlexStim™ Software 2.2 is now available online for the PlexStim Electrical Stimulator 2.0, an electrically isolated, individually programmable, constant current stimulator system. The new release now enables up to 32 independent stimulation channels via (two 16 channel devices) to be controlled using a new PlexStim software development kit (SDK).

PlexStim can generate arbitrary waveform patterns initiated from either the software interface or from externally triggered digital inputs with an unprecedented 30nA resolution and 1μsec temporal resolution. The graphical user interface (GUI) makes it easy to generate bi-phasic rectangular pulses and bursts of pulses repeated at specific rates. More complicated rectangular waveforms and non-rectangular arbitrary waveforms may be defined in and loaded from a simple text file.

Every stimulation pattern can be started and stopped either manually within the GUI, or with an external digital trigger (TTL). Complex stimulation patterns can be delivered in this way with precise timing based on different triggers. Each channel has a dedicated digital input that may be used in an edge triggered or level triggered (gated) mode to initiate stimulation with microsecond latency. Each channel also has a dedicated digital output signal to third party devices at the precise time when stimulation is occurring. The actual current and voltage delivered to each electrode can be conveniently monitored on a per-channel basis with stimulation currents defined with 16-bit precision up to ±1mA and delivered with ±10V compliance.
