Record & Stimulate

Data capture

Spike2 records waveform, time-stamp and marker data. Waveform channels can be captured at different sampling rates, with synchronising stimulus and pacing pulses logged as time-stamp data to the same file. Text comments placed in the record during data sampling are easily located for review and analysis of experiment stages.

Data feature detection

Active cursors search for features in waveform data and latch to time-stamps. You can also position cursors with "expressions", such as , Cursor (1) +5 to force a second cursor five seconds in advance of the first for comparative area measurements.

• Search for features including peaks, troughs, threshold crossings, slope measurements, percentage repolarisation and event markers on multiple data channels
• Use up to ten active cursors in a data file view

Stimulation

The CED 1401 interface generates pacing pulses and stimulus amplitude values via Spike2's built-in sequencer. A graphical editor with drag-and-drop interaction allows fast and easy creation of stimulus protocols. For more complex output and control requirements, a text editor enables direct access to the sequencer code. Further on-line control of the outputs is available through script interaction.

• Output pulse trains, variable amplitude pulses, ramp, sine and arbitrary waveforms during sampling
• Respond in real-time to changes or features in the sampled data
• Switch between different output protocols with a mouse-click
