The cat's pons was isolated by two brainstem transections, at the junction of medulla and pons and at the junction of pons and midbrain.In the differented pons the EEG acticvity was virtually absent, whereas the spatial density of active units and the rate of their spontaneous spike activitry were at a high level.In the pons of control preparations with brainstem transected only at the ponto-midbrain junction the EEG activity was present, while the single-unit activity was such as in isolatesd pons.The electrical activity of the isolated pons was similar to that previously described in the cat's isolated midbrain.The discrepancy between EEG and a single-unit activity suggests that in the deafferented pons or midbrain many neurones are asynchronously autoactive.Also, these results show that a flat EEG record is not necessarily a sign of absence of the neural activity and neural death.
