Case pg87. Soma notes In some expts retrogradely labeled cells were also identified in retrosplenial cortex. --Not seen in every expt-, Disc: [Wyss&Sri84, BR293:1; Gerf&Clav81, BR224:291] report no connx but weak connx possible.. Terminal notes Less spread of tracer along miropipette track and less likely to have labeled afferents to the DR. In 6 expts the WGA-HRP ins were restricted to the median and paramedian raphe nuclei, and these cases were analysed in detail..

Case pg91. Soma notes no labeled cells were identified in retrosplenial cortex. Terminal notes Sites of D-[3H]ASP injections at 10e-3M are illustrated in fig8CD. A central zone of high silver grain density was confined to the median-parramedian raphe while a peripheral zone reached the praedorsal fascicles & extended into DR.

Case pg91. Soma notes some regions indicated by CT experiments as afferents to median raphe were devoid of retrogradely labeled cells even after inj of 10E-2 M D-[3H]ASP. These included retrosplenial cortex?. Terminal notes Injs of 10E-2 M D-[3H]asp. Inj site: large. Central zone of high silver grain dens ?~1mm medlat & into overlying dorsal raphe & ventral tegmental nuc. Surrounding zone of lower grain dens extended into mesencephalic teg. & interpeduncular nuc..
