Abstract
Neural probes have become the most importan t tool
for enabling neuroscientists to place microelectrode sensors close
to individual neurons and to monitor their activity in vivo .W i t h
such devices, it is possible to perform acute o r chronic extra-
cellular recordings of electrical activity from a single neuron or
from groups of neurons. After the many developments in neural
implants, it has become clear that large arr ays of electrodes
are desirable to further investi gate the activity perfo
