    Description / Table of Contents: The degree of electric charging of metal surfaces due to retarding of neutral metallic and semiconducting particles having various velocities has been determined. The effects are supposed to result from the exo-emission of electrons the amount of which depends on the velocities, masses, and impact angles of the particles.From the strong differences between the reactivities of solid substances during and after mechanical working it is concluded that the observed exo-emission is caused by exitation states at submicroscopic surface points.
    Notes: Die elektrische Aufladung von Metalloberflächen bei der Impuls-Bremsung nicht geladener, fliegender, metallischer und halbleitender Partikel verschiedener Geschwindigkeiten wird gemessen. Die beobachteten Erscheinungen lassen sich aus der Exo-Emission von Elektronen herleiten. Diese ergibt sich u. a. aus dem Zusammenhange zwischen der Elektronen-Austrittsarbeit der beteiligten Partner und der Größe der gebremsten Impulse. Die Ladungs-Übergänge hängen Übersichtlich vom Quadrat der Geschwindigkeiten, von der Masse und vom Auftreffwinkel der Körner ab. Einflüsse mechanischer Vorbehandlung der Festkörper, entsprechend früheren Beobachtungen, werden bestätigt.Im Zusammenhange mit den beobachteten großen Unterschieden des Reaktionsvermögens von Festkörpern während der Bearbeitung und nach ihrem Abschluß lassen die beobachteten Exo-Emissionen auf das Auftreten erhöhter Anregungszustände an submikroskopischen Orten während der Impuls-Bremsung schließen.

    Notes: Summary Central projections of the nervus terminalis (n.t.) in the goldfish were investigated using cobalt- and horseradish peroxidase-tracing techniques. Single n.t. fibers were identified after unilateral application of cobalt chloride-lysine to the rostral olfactory bulb. The central course and branching patterns of individual n.t. fibers were studied in serial sections. Eight types of n.t. fibers are differentiated according to pathways and projection patterns. Projection areas of the n.t. include the contralateral olfactory bulb, the ipsilateral periventricular preoptic nucleus, both retinae, the caudal zone of the periventricular hypothalamus bilaterally, and the rostral optic tectum bilaterally. N.t. fibers cross to contralateral targets in the anterior commissure, the optic chiasma, the horizontal commissure, the posterior commissure, and possibly the habenular commissure. We propose criteria that differentiate central n.t. fibers from those of the classical secondary olfactory projections. Branching patterns of eight n.t. fiber types are described. Mesencephalic projections of the n.t. and of secondary olfactory fibers are compared and discussed with regard to prior reports on the olfactory system of teleosts. Further fiber types for which the association with the n.t. could not be established with certainty were traced to the torus longitudinalis, the torus semicircularis, and to the superior reticular nucleus on the ipsilateral side.

    Notes: Summary Central pathways of the nervus terminalis (n.t.) in the bichir, Polypterus palmas, were studied with the use of tracing techniques. After application of horseradish peroxidase to the unilateral olfactory mucosa labeled n.t. fibers were traced in seven distinct bundles through the subpallium. Projection areas are found in the precommissural ventral nucleus of the area ventralis telencephali ipsilaterally, the anterior commissure and commissural parts of the periventricular preoptic nucleus bilaterally; few n.t.-fibers cross via the anterior commissure to the contralateral side; no fibers were observed to turn rostrally to the contralateral olfactory bulb. Major targets of the n.t. include a restricted ventral part of the periventricular preoptic nucleus at the level of the optic chiasma bilaterally, and the periventricular nuclei located between the thalamic nuclei and the hypothalamus bilaterally. N.t. fibers continue their course through the ipsilateral hypothalamus and are traced as far as the mesencephalic tegmentum ipsilaterally. N.t. terminations are found consistently within the boundaries of periventricular cell nuclei, suggesting axosomatic synaptic contacts. We propose a differentiation of the n.t. ganglion cells into a distal (mucosal) and proximal (bulbar) type regarding the peripheral cell processes. Our findings are compared with those of other reports on the n.t. system.

    Notes: Summary After application of various neuronal tracers (horseradish peroxidase, cobalt-chloride lysine, true blue) to the ganglion of the nervus terminalis a small number of neurons was retrogradely labeled in the mesencephalon. As revealed by combined horseradish peroxidase and catecholamine-fluorescence techniques these neurons are located in the isthmic area immediately rostral to, but not within the locus coeruleus. Cobalt-labeled axons of the mesencephalic neurons were traced individually in serial sections. Neurons projecting contralaterally cross in the horizontal commissure. Tracing of single fibers provided no evidence for axon collaterals within this pathway. Retrograde labeling reveals two different types of isthmic neurons afferent to the ganglion of the nervus terminalis: One smaller-sized type is located bilaterally and consists of four to six neurons; another type possessing many dendritic processes was consistently found as only one single cell located contralateral to the side of injection. The existence of two types of neurons was confirmed by their cytological differences: The small-sized type receives only sparse perisomatic input, while the large-sized type shows heavy somatic and dendritic, probably monoaminergic innervation.

    Notes: Summary The terminal nerve has been described in all vertebrate classes, with the exception of cyclostomes and birds. With regard to this question, we have examined representatives of these two classes using tracer techniques, and found a terminal nerve in larval lampreys and young domestic mallards. Horseradish peroxidase or cobaltous lysine was injected into the olfactory mucosa, which is known to be innervated by peripheral branches of the terminal nerve. The brains were then searched for labeled, centrally directed fibers of the terminal nerve that project further caudally than the glomerular layer of the olfactory bulb. In larval lampreys, centrally projecting fibers of the terminal nerve were found in the tel-, diand mesencephalon. Termination of labeled fibers was observed in the hypothalamus. Some fibers of the terminal nerve cross to the contralateral side via the commissure of the posterior tuberculum. In young ducks, the terminal nerve projects ipsilaterally along the medial edge of the telencephalon.
