Simultaneous recording with 30 microelectrodes in monkey visual cortex.
A 30-fold multielectrode for extracellular recording of neuronal spikes is described. Single neuronal spikes were isolated simultaneously by about half of the electrodes. The technique has been applied to demonstrate the spatial distribution of ocular dominance and orientation preference in striate cortex.
