32 channel microelectrode array  (NeuroNexus Technologies)

Article Title: Odor modality is transmitted to cortical brain regions from the olfactory bulb.
Article Snippet: .. A 32-channel microelectrode array (MEA, A4x2tet, NeuroNexus, MI) was inserted 400-μm deep from dorsal surface of OB targeting tufted and mitral cell populations. ..

Article Title: Multichannel electrophysiological recordings reveal independent modulatory actions of on-cells and off-cells in the rostral ventromedial medulla on pain processing.
Article Snippet: .. A 32-channel microelectrode array (NeuroNexus, USA) was slowly advanced into the target nucleus to a depth of 5.00 mm below the cortical surface. .. After a 20-minute stabilization period, electrophysiological signals were recorded using a data acquisition system and preamplifier (Blackrock Microsystems, USA) at a sampling rate of 30 kS/s.
