A Head Mounted Wireless Neural Recording and Stimulation System for Freely Behaving Primates

Cell bodies expressing the immediate early gene ‘cfos' (green) and illustrate those cells in somatosensory cortex that were directly activated by highly selective excitation of cells from motor cortex. Other cell classes in the somatosensory cortex are labeled in blue (hoechst).

Excitatory neuronal cell bodies and dendrites in the motor cortex expressing channelrhodopsin2 (a light gated ion channel) illustrated in red (mCherry). These can be activated with blue light (473 nm). Other neuronal cell classes in the motor cortex are labeled in blue (hoechst).

Traces of implanted microelectrodes near neuronal cell nuclei (labeled in green) in the medial Prefrontal Cortex.
