Using NeuroNexus linear arrays, dense sampling through the auditory cortex enabled computation of bipolar derivation LFPs for supragranular and infragranular layers. LFPs were also sampled across the posterior auditory field within the ectosylvian sulcus. This study is a great example of using NeuroNexus probes to target hard-to-reach areas.

This publication in eNeuro provides highlights valuable data obtained from acute recordings with standard NeuroNexus catalog probes in macaque visual cortices. The researchers covered the skull with acrylic resin, performed a craniotomy through the resin, then inserted silicon probes through a slit in the dura. Re-use of the probes and multiple recordings in the same animals were achieved with this method. Original recordings were published here. The present study’s computational results suggest that saliency of visual stimuli are represented in primary visual cortex.

Neuronexus A2x16-10mm-150-500-177-A32, 2-shank laminar probes were used to record the control frequency tuning profile of the guinea pig inferior colliculus. The animals were then acutely deafened and probe recordings were used to characterize inferior colliculus activity during use of cochlear implants with different stimulation profiles. This study in Hearing Research points to a solution for reducing channel interactions in cochlear implants, with the potential to improve speech detection for cochlear implant users.
