Video Summary

The session focused on intracortical high-density systems for neural recording and stimulation, highlighting their uses and challenges. Dr. Ahmed Raslan and Kelly Collins introduced the session, noting the involvement of experts in the field, including Dr. Sid Keshe and other contributors discussing advanced technologies. Dr. Keshe emphasized new technologies allowing enhanced neural recordings and stimulation, changing how the brain is understood in terms of physiology and neurology. The session covered topics like the high-resolution capabilities of current devices, comparing advancements with past technologies like grids and strips. Dr. Keshe's talk detailed the use cases and challenges associated with these technologies, discussing intracortical arrays and their crucial role in expanding our understanding and application of neural interface technologies.<br /><br />Dr. Shadi Daye from UC San Diego provided insights on crafting multi-thousand channel thin film electrodes, detailing how these innovations support high-density recordings that are necessary for extended brain coverage. Dr. Daniel Kramer from the University of Colorado discussed applications of these technologies in brain-computer interfaces, emphasizing their role in sensorimotor restoration and executive functional studies.<br /><br />The session also included short abstracts from other researchers. Brian Chung presented on beta EEG power modulation within the orbitofrontal cortex, finding differential beta-band power modulation between movement execution and inhibition phases. Dr. Jan Vesper presented findings from a registry comparing awake versus asleep DBS placement in Parkinson’s patients, noting similar motor outcomes regardless of surgical conditions. Ghassan Makul discussed seizure network dynamics, finding network interactions that suggest suppression motifs associated with seizure phases, presenting potential targets for neuromodulation.<br /><br />The session concluded with discussions that emphasized regulatory challenges, ethical concerns, and the need for collaborative efforts to advance and apply these technologies effectively in clinical settings.
