|---|---|---|---|---|---|---|---|
| 506 | Superior colliculus | Pedunculopontine nucleus | light | HRP/WGA | Case pg155, fig2. Soma notes A large centrally-located (WGA-HRP) inj with a central zone that extended across all collicular lvls. Slight invasion of intermed blue/white zone of ?PPT, NOT & dorlat PAG. Same main features in 5 other large & some similarities with small injs. Terminal notes Some fibres run to the cunieform nucleus and surrounding areas. These include?the pedunculopontine tegmental nucleus. Label was weak. Label heavier (extended caudally to give weak label in PB and DTN) after injections more lateral than 2302. | Redgrave P, Mitchell IJ, Dean P., 1987 | |
| 924 | Superior colliculus | Pedunculopontine nucleus | exists | HRP/WGA | Case pg162, fig5,6. Soma notes Injection site --WGA-HRP- centred on the lateral part of the intermediate white layer. Intermediate blue-white zone extended across all collicular layers and encroached slighlty onto underlying tegmentum. Terminal notes Fibres ?reach part of the pedunculopontine/parabrachial area that is ventrolateral to the superior cerebellar peduncle. contra.. | Redgrave P, Mitchell IJ, Dean P., 1987 | |
| 937 | Superior colliculus | Pedunculopontine nucleus | very light | HRP/WGA | Case pg155, fig2. Soma notes A large centrally-located (WGA-HRP) inj with a central zone that extended across all collicular lvls. Slight invasion of intermed blue/white zone of ?PPT, NOT & dorlat PAG. Same main features in 5 other large & some similarities with small injs. Terminal notes Some fibres run to the cunieform nucleus and surrounding areas.
