Figure 9. Synchrony among unique sets of VTA putative dopamine neurons.
(A) Peri-event rasters (1–20 trials) and histograms of two simultaneously recorded type-1 neurons in response to free fall event, and (B) the cross-correlogram between these two neurons when the mouse was freely behaving. (C) The averaged cross-correlograms between simultaneously recorded type-1 neurons (48 pairs during freely behaving, and 35 pairs during sleep). (D) Peri-event rasters and histograms of two simultaneously recorded type-1 and type-2 neurons in response to free fall event, and (E) the cross-correlogram between these two neurons during freely behaving. (F) The averaged cross-correlograms between simultaneously recorded type-1 and type-2 neurons (6 pairs during both freely behaving and sleep). (G) Peri-event rasters and histograms of two simultaneously recorded type-3 neurons in response to free fall event, and (H) the cross-correlogram between these two neurons during freely behaving. (I) The averaged cross-correlograms between simultaneously recorded type-3 neurons (15 pairs during freely behaving, and 12 pairs during sleep). (J) Peri-event rasters and histograms of two type-1 and type-3 neurons (simultaneously recorded from one tetrode) in response to free fall event, and (K) the cross-correlogram between these two neurons during freely behaving. (L) The averaged cross-correlograms between simultaneously recorded type-1 and type-3 neurons (12 pairs during freely behaving, and 10 pairs during sleep). Free fall, 30 cm high.
