Switching Headstage


TDT’s switching headstage is an advanced headstage for seamless closed-loop electrophysiology that can rapidly stimulate and record on the same electrode. Record from an electrode array while simultaneously stimulating individual electrode channels and eliminate the need to physically connect and disconnect!

The switching headstage uses fast switches (<200 µs) to minimize the delay between stimulation and recording and high-quality amplifiers to condition the signal. Controlled from the Subject Interface through our Synapse software, you can easily program standard mono- and biphasic pulses as well as complex stimulation paradigms for current steering and arbitrary waveforms.
