    I'm proud that our work decoding speech from intracortical multielectrode arrays won this year's BCI Award! Congrats to the whole team and thank you to the award organizers, sponsors, and judges.

    One can even jazz things up with nonlinear gain scaling akin to most OS's computer mouse behavior (whether you realized it or not).

    Neural dynamics motif #2: Strong rotatory dynamics are present during speech production. Here we applied the methods of Churchland, Cunningham et al 2012:

    Neural dynamics motif #1: Population activity is dominated by a large condition-invariant signal (CIS) when initiating speaking. Here we applied the methods of Kaufman et al 2016 (): 12/

    Could these signals be useful for building speech BCIs to help people who cannot speak? We think so! We could decode amongst a set of syllables pretty well, despite having only 200 electrodes in a sub-optimal part of the brain. 8/

    Most neurons also responded to simple (non-speaking) movements of the lips, jaw, and tongue, so we think this activity reflects motor control of the articulators, rather than higher-level processes like language. 7/

    The very cool, and surprising, result was that lo and behold, there was strong firing rate modulation on many electrodes when producing different speech sounds. Here’s an example neuron's spike rasters and trial-averaged firing rates: 6/

    We asked two of our participants, who are able to speak, to do a simple prompted speaking task. 5/

    I'm excited to present our new work on motor cortical dynamics during human speech at next Friday (and again the following Wed afternoon at ). Teaser: these neural state trajectories may look familiar (presented as in et al. 2016), but...(1/2)

    I'm very excited to speak about some rather surprising new results at : we found speech-related spiking activity in dorsal 'arm' motor cortex. Come hear more on Wednesday afternoon!

    Who's going to 2018 Meeting? If you're there, come see our high neural degrees-of-freedom decoding poster (Wed PM). DOF isolation/simultaneity measurements in VR, robot arm use, multi-effector fails, and for dessert we mapped 4 DOF + click to the PC game Portal:

    SfN folks: I'm talking about decoding high degree-of-freedom movement intentions from people with paralysis using intracortical electrode arrays. Wednesday, 9:30 AM, Room 150A. Come see the videos for 4 DOF closed-loop cursor trajectories like these.
