Tectal projection neurons were labeled by retrograde transport of horseradish peroxidase
(HRP) or cobaltic‐lysine. The tracer substances were delivered iontophoretically or by …

With the aid of the cobalt labeling technique the following termination areas of the
vestibulocochlear nerve are found in the frog. The nucleus cochlearis receives fibers from …

In the present study an isolated preparation of the complete anuran central nervous system
(CNS) is described which can be kept alive for several days and allows tracing …

The course and sites of termination of dorsal column fibres in the lamprey brainstem are
described along with their brainstem relays projecting to reticulospinal neurons. Dorsal …

Distribution and morphology of the cells of origin of the descending spinal pathways and
their axonal courses were studied in the himé salmon, using retrograde labelling with …

Using the cobalt labelling technique in the rat, mesencephalic afferent fibres were shown in
all three divisions of the trigeminal nerve. The descending branches of mesencephalic …

With the aid of cobalt‐filled intracellular electrodes, responses evoked by electrical and
visual stimulation were recorded from tectal neurons. Diffuse light and “edge” and “spot” …

Visual stimuli elicit motor responses in lampreys. These responses rely, in part, on the
activation of reticulospinal (RS) neurones which constitute the main descending pathway in …

Cell-cell communication through gap junctions was examined in Xenopus laevis embryos
between the 16cell and early blastula stages using Lucifer Yellow, Fluorescein, lead EDTA …

Primary projections of the anterior and posterior lateral‐line nerves were traced by means of
transganglionic transport of horseradish peroxidase in species belonging to five of the six …
