Figure 2. Short- and long-term cocaine administration periods differentially affect the persistence of cocaine-induced spine density increases in nucleus accumbens.

Figure 2

Reports of cocaine-induced spine density changes were grouped into short-term (3–11 days, green) and long-term (12–37 days, blue) days of cocaine treatment. A dashed blue line indicates no long-term dosing study examined time points at <24 hours of cocaine withdrawal. A table reporting the number of positive versus negative reports is given below.
