Direct projection from the dorsal hypothalamic area to the nucleus raphe pallidus: a study using anterograde transport with Phaseolus vulgaris leucoagglutinin in the rat.
Article in Experimental brain research, 1989. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
A hypothalamic projection to the nucleus raphe pallidus of the medulla was examined using the anterograde tracing technique based on Phaseolus vulgaris leucoagglutinin (PHA-L) in the rat. After the iontophoretic application of PHA-L to the dorsal hypothalamic area, labeled fibers that finally ended in the nucleus raphe pallidus were observed descending through the most medial part of the ventral tegmental area and the nucleus reticularis tegmenti pointis to reach the medial aspect of the pyramid. Many varicose fibers forming a loose plexus were observed in the nucleus raphe pallidus, especially ventrally. The ventral surface of the pyramid and the most ventral region of the nucleus reticularis paragigantocellularis lateralis (PGCL) contained labeled varicose fibers. At the electron microscopic level, the labeled profiles in the nucleus raphe pallidus were small-sized unmyelinated axons and axon terminals. Labeled axon terminals containing spherical synaptic vesicles formed synapses on spine-like protrusions or small-sized dendritic shafts. These results strongly indicate that neurons in the dorsal hypothalamic area have a direct connection with neurons in the nucleus raphe pallidus and the ventral part of the PGCL. The possible involvement of this pathway in cardiovascular regulation was discussed.
