SpikeLog64

SpikeLog64 is a single-board lightweight 64-channel neural logger that mounts vertically and weighs just 3 grams. It amplifies and digitizes single-cell neural signals and stores all data onto a MicroSD memory card. Along with neural data, it records ultrasonic audio using its on-board microphone and includes a 9-axis motion sensor.

Compatible Electrode Interface Board

SpikeLog64 connects to electrodes with its two parallel Omnetics connectors type A79025-0001.  The center lines of these connectors are spaced 2.69mm. Deuteron makes a circular electrode interface board that matches SpikeLog64. Click here for details.

Interchangeable with Intan Technologies’ 64-channel amplifier boards.

The type and spacing of these connectors is identical with that on the Intan RHD2164 amplifier board. It is thus possible to use the Intan’s data aquisition systems or Intan’s USB Interface Board in conjunction with that amplifier board to adjust electrodes and to measure their impedance, and to conduct wired measurement experiments. Then when the experiment requires the animal to be fully freely-moving, one can remove the Intan amplifier board and attach the SpikeLog64 logger.
