SpikeLog-64 is a 64 channel single-board neural logger that also features ultrasonic audio and motion sensor logging. At a size of just 20 x 29mm and a weight of only 3.3g (not including battery), this board is a perfect, lightweight solution for recording neural signals in small animals such as rats and marmosets, among others. It’s on-board microphone is capable of recording animal calls up to 80kHz, and its 9-axis motion sensor records accelerometer, gyroscope and magnetometer data. For specifications see here. It comes in several variants, each with different features (see below for details on variants).

Variants
SpikeLog-64C
Includes wired streaming capabilities using Open-Ephys and Intan’s data aquisition systems making it possible to adjust electrodes, measure their impedance, and conduct wired experiments using the SpikeLog-64C headstage, that is, without the need for an Intan amplifier board. When the experiment requires the animal to be fully freely-moving, one can remove SpikeLog64 logger from the wired connection.
SpikeLog-64D
Includes altimeter capability and plug-in GPS module.
SpikeLog-64E
Includes a co-processor for external SPI sensors and IR remote control for turning on/off.
All variants are available in 32-channel versions at a reduced price
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 neural input connectors is identical with that on the Intan RHD2164 amplifier board. With this amplifier board connected to Intan’s data aquisition systems 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.
