NeuroNexus chronic, 32-channel silicon probes were implanted chronically in behaving adult mice expressing autism-spectrum phenotypes. Paterno et al. from Scott Baraban’s lab at UCSF utilized A4x8-5mm-200-400-703-CM32 probes to record hippocampal LFPs and specifically gamma oscillations. They also used hippocampal sharp-wave ripples (SWR) and dentate spikes to localize the probe. Final probe location was determined with DiI, which was applied before implant.
