Congratulations to Yun Wen Chu from the Scott Pluta Lab at Purdue University for defending their PhD thesis in December, titled “Neural Mechanisms for Tactile Stimuli Selection.” In their research, they used a Neuronexus 128-channel probe with 3 shanks (A3x43_42_43-edge-5mm-20-250-177-I128) to investigate the mouse primary somatosensory cortex (S1) and the superior colliculus (SC) while the animal performed an active spatial discrimination task. These probes revealed both non-linear summation of multi-whisker inputs in S1 and complex response patterns in SC, including facilitation and suppression during tactile tasks. By providing high-resolution spatial and temporal data, Neuronexus technology was instrumental in uncovering how tactile stimuli are processed and integrated across cortical and subcortical regions.
