Head-mounted wireless neurosensor (Brown, 2014)

One-line verdict: Cut the tether for primate cortical recording: full-spectrum signals during natural locomotion and sleep, over a receiver network that the authors say scales to hundreds of channels and large environments.

Overview

What it is: A compact, lightweight, low-power, head-mounted wireless neurosensor with a high data rate. It is described as electrically safe and compatible with most existing neural probes.

What was shown: Cortical neuron populations in freely behaving nonhuman primates during natural locomotion and sleep-wake transitions in ecologically equivalent settings.

Link design: A spatially distributed network of synchronized receivers, scalable to hundreds of channels and vast environments.

Relation to the 2013 system: The 2013 entry is a subcutaneous package for clinical-style use. This 2014 device is a head-mounted unit for free behavior.
