FB128 Neural Simulator

The FB128 Neural Simulator is an essential tool for testing experimental paradigms during the design phase and debugging problems when they arise. The compact, battery-operated device simulates neurological waveforms or tones that can be output directly to a ZIF-Clip® headstage. Neurological simulations consist of an LFP component and spike components. Up to eight spike waveform shapes may be included depending on the mode.

FB128 Neural Simulator

The simulator can operate in eight different modes and includes an inhibitory/excitatory option for even more output variations. The simulation modes are listed on the face of the module and LEDs indicate which is active. Operational buttons or switches, a trigger input, and a charger input are positioned on one end of the module and output connectors for headstage connection are positioned on the other.

The FB128’s flexible operational modes include:

  • Normal – neurological waveforms, including spike waveforms and LFP
  • Hash – Normal with spikes scaled down by a factor of 2
  • LFP Only – Normal with spikes scaled to 0
  • Tetrode – neurological LFP waveforms with spikes, where spikes on each group of 4 channels fires synchronously
  • Sync 100 Hz – neurological LFP waveforms with spikes on all channels firing synchronously at 100 Hz fixed rate
  • Tone 30 Hz – 30 Hz tone at 1000 µV on all channels
  • Tone 1000 Hz – 1000 Hz tone at 100 µV on all channels
  • Tone Ref – 100 Hz tone at 1000 µV on Reference channel only
