[Neuronal background activity in surviving slices of guinea pig visual cortex].
Visual cortex slices of guinea pig were maintained in vitro. Background neuronal activity was recorded extracellularly. Five types of the activity were revealed: single regular, single irregular, bursting, group and mixed discharges. The regular pacemaker-type discharges were encountered more often than other types. Such regular activity was never observed in the neocortex in vivo. The type of the background activity of one and the same neuron may change with time.
