In the NAc core and in the olfactory tubercle, similarly to the CPu, D2 receptors are located in GABAergic neurons coexpressing enkephalin, whereas in the NAc shell D2 receptors are expressed in neurotensin-containing neurons (Le Moine et al., 1990b Diaz et al., 1994 Le Moine and Bloch, 1995 Delle Donne et al., 1996). In addition, in both the NAc and the olfactory tubercle an overall co-distribution of D2 receptor and TH immunoreactivity was found, consistent with the presence of D2 autoreceptors. In the shell portion of the NAc, D2 immunoreactivity was detected with similar frequency in terminals and dendritic spines (Delle Donne et al., 1997). 

Hersch et al. (1995) found that D1 immunoreactive terminals presynaptic to symmetrical synapses were exceedingly rare whereas the D2 immunoreactive terminals were quite frequent. Synapses formed by D2 immunoreactive terminals were not easy to identify due to a lack of pronounced pre or postsynaptic densities, but many D2 positive presynaptic terminals made symmetrical synapses with dendritic shafts and spines. Consistent with this, many presynaptic D2 receptors were also seen in terminals which were not positive for TH, suggesting they may be heteroreceptors (Sesack et al., 1994). This is confirmed by the demonstration of the D2 positive GABA axon terminals presynaptic to symmetrical synapses (Delle Donne et al., 1997).

The concept of coal alkylation has been expanded to a variety of studies relating to coal structure (Sternberg et al., 1971 Sternberg and Delle Donne, 1974 Wachowska, 1979 Alemany et al., 1981 Wender et al., 1981 Handy and Stock, 1982). This is, essentially, a method of reductive alkylation, which, as a first step, necessitates reacting the coal with metallic potassium and naphthalene in...
