Center for Neurotechnology

The Center for Neurotechnology listed nine new papers spanning experimental and computational neuroscience, neural interfaces and neuroethics. The selection includes Smart Dura for multimodal neural recording and modulation, work on transcutaneous spinal-stimulation trials, primate optogenetics, co-adaptive interfaces, motor-cortex activity and participatory neuroethics research.

Researchers at the Center for Neurotechnology at the University of Washington recorded from two male monkeys with high-density laminar microelectrode arrays and found that reaching-related activity in frontal motor cortex is unevenly distributed both across the cortical surface and with depth. Target-direction information varied sharply between neural populations, but the amount of task information a population carried predicted which populations shared similar temporal dynamics. The authors say the pattern should inform where electrodes are placed in future brain-computer interface implants.
