This prof talked about his research interest of engineering brain-machine interfaces. In other words, controlling machines with mere thought, remotely.
He has lots of DoD funding (no surprise...) and the advertisement industry is into this as well (knowing when there's high brain activity upon seeing certain images... even before conscious realization.)
He had occasional strange stutters, which was a tad distracting. I think it's because he spoke very fast and his thought process lagged during moments of stuttering. LOL. I think profs who talk faster in general tend to be easier to follow, assuming coherence.
There is an optimal speed, I've found. But all else being equal, I've found that going too fast is better than going too slow... because the attention level perks up in the former case and wanders elsewhere in the latter case.
