PMID-10561437[0] Motor cortical representation of speed and direction during reaching
- velocity is represented in the motor cortex.
- they developed an equation relating firing rate to the position and velocity.
- EMG direction had significantly different tuning from the cortical activity
- the effect of speed on EMG was also different.
- used single-electrode recording - 1,066 cells!!
- introduce the square-root transformation of the firing rate (from Ashe and Georgopolous 1994)
