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.
SpikeLog-128 is a single-board 128 channel logger that includes a 9-axis motion sensor. It is only 30 x 30mm and weighs just 4.4g, making it suitable for recording neural signals in animals as small as rats or marmosets. The neural inputs are connected via a pair of 70-pin molex connectors. In general, it will connect to the electrode assembly via an adaptor board. For specifications see here.
