Nucleus ruber

The body burden of bismuth is very low the daily oral intake of Bi, combined with inhalational intake, is estimated at 5-20 jg (Tsalev and Zaprianov 1983). Bismuth is one of the trace elements present in tissues, with relatively high levels being found in the nucleus ruber (Leonov 1956). Following its absorption, bismuth is found in all tissues, though no relationship between tissue concentration and therapeutic effect has yet been established. It is... 

Fig. 101. Diagram of the projections of the dentate and interposed cerebellar nuclei (CN) and the mossy and climbing fiber recurrent circuits. The non-GABAergic projections of the nuclei divide in ascending (A and C) and descending (B) branches. The descending branch terminates in the nucleus reticularis tegmenti pontis (NRTP), one of the main sources of the mossy fiber collateral projection to the nuclei. The ascending branch terminates in the red nucleus (n. ruber), the nuclei of the mesodiencephalic junction MDJ, a relay in the recurrent cerebellomesencepho-olivary loop, and in the ventral tier nuclei of the thalamus (VA/VL). The GABAergic nucleo-olivary projection (2) terminates in the inferior olive (lO). Courtesy of Dr. T.J.H. Ruigrok.
