the reference is:

Georgopoulos, A.P., Schwartz, A.B. & Kettner, R.E. (1986). Neuronal
population coding of movment direction. Science, 233, 1416-1419.

it is about perception *and* movment.  the finding was that  the activity
of the neurons transformed into a vector predicted the direction of
movement of the animals arm.  the vectors were congruent with the animals
'spatial planning of movement'.
