A sample of the multiunit firing of the VTA dopaminergic neurons in the control group
A sample trace of the multiunit firing of the VTA dopaminergic neurons in the control group; B. The histogram of the firing of the VTA dopaminergic neurons of the control group. In the control group with naive animals, the VTA dopaminergic neuronal firing under standard condition was recorded up to 120 min. The Mean±SD firing rate of the neurons in the control group was 4.97±1.2 spikes/second. The mean firing in each minute calculated from the averaged firing in each second in every minute. The data are presented as Mean±SD.
