The Central Nucleus of the Amygdala Modulates Gut-Related Neurons in the Dorsal Vagal Complex in Rats

Using retrograde tract-tracing and electrophysiological methods, we characterized the anatomical and functional relationship between the central nucleus of the amygdala and the dorsal vagal complex. Retrograde tract-tracing techniques revealed that the central nucleus of the amygdala projects to the dorsal vagal complex with a topographic distribution. Following injection of retrograde tracer into the vagal complex, retrogradely labelled neurons in the central nucleus of the amygdala were clustered in the central portion at the rostral level and in the medial part at the middle level of the nucleus. Few labelled neurons were seen at the caudal level. Electrical stimulation of the central nucleus of the amygdala altered the basal firing rates of 65 % of gut-related neurons in the nucleus of the solitary tract and in the dorsal motor nucleus of the vagus. Eighty-one percent of the neurons in the nucleus of the solitary tract and 47 % of the neurons in the dorsal motor nucleus were inhibited. Electrical stimulation of the central nucleus of the amygdala also modulated the response of neurons in the dorsal vagal complex to gastrointestinal stimuli. The predominant effect on the neurons of the nucleus of the solitary tract was inhibition. These results suggest that the central nucleus of the amygdala influences gut-related neurons in the dorsal vagal complex and provides a neuronal circuitry that explains the regulation of gastrointestinal activity by the amygdala.     

Scanning electron microscopy of the connective tissue along the lateral wall of the mouse cochlear duct with special reference to the external sulcus cells

The external sulcus cells in the lateral wall of the cochlear duct insert cell cords into the connective tissue. To examine the shape, arrangement, and distribution of the sulcus cell cords in the cochlear duct in adult mice, the external sulcus cells were removed by chemical maceration methods, and the connective tissue exposed. The holes for the insertion of the sulcus cell cords along the entire course of the cochlear duct could thus be observed by scanning electron microscopy. A zone perforated with the holes was seen in the lateral region of the area between the stria vascularis and the lateral edge of the basilar membrane, this zone extending from the basal end of the hook to the helicotrema. In the hook and basal half turn, the holes possessed large fusiform openings and branched in the connective tissue toward the outer bony wall. In the apical turn, the holes displayed small round openings and were shallow, having a small number of branchings. The width of the perforated zone, the population density of the openings of the holes and the area proportion of the openings per unit surface area in the lateral wall decreased from the base to the apex of the cochlear duct. The regional differences in the organization of the sulcus cell cords suggest that the external sulcus cells function in close relation to regional auditory functions in the cochlear duct.

Developmental differences in the ossification process of the human corpus and ramus mandibulae

A correlation was sought between the organization of the dental crest and the ossification of the corpus mandibulae in 14 human embryos and 13 human fetuses. The different types of ossification between the corpus and the ramus mandibulae suggest that the cartilago mandibularis (meckeliensis) guides the formation of the mandibula, while the dental crest acts as a coorganizer. In the area of the foramen mentale, the lamina dentalis begins to invaginate (to give rise to the dental crest), and at this level intramembranous ossification of the corpus mandibulae commences. These findings, together with the presence of the cartilago mandibularis before the appearance of the dental crest, and the fact that the former is seen along the entire length of the mandibula (from the symphysis mandibulae to the capsula otica), support the hypothesis that the dental crest, rather than the cartilago mandibularis, acts as the coorganizer in the corpus mandibulae. © 1993 Wiley-Liss, Inc.

Characteristics of the Time Course of Evoked Secretion of Transmitter Quanta in Different Parts of the Motor Nerve Ending in the Frog

Experiments were performed on neuromuscular preparations from frogs, in which three extracellular microelectrodes were used to record nerve ending currents and single-quantum endplate currents simultaneously from the proximal, central, and distal parts of single synaptic contacts. The rate of propagation of excitation across terminals was measured, along with the minimum synaptic delay, the intensity, and the degree of synchronicity of the secretion of transmitter quanta in different parts of the nerve ending, and the relationships between these factors and the calcium ion concentration in the medium. These studies showed that along with gradients in the rate of conduction of excitation and the intensity of secretion in different parts of the ending, there were also differences in the kinetics of the release of transmitter quanta. As the distance from the end of the myelinated part of the axon increased, the rate of conduction of the nerve impulse and the duration of the synaptic delay decreased, while the synchronicity of the release of quanta increased. Increases in the calcium concentration in the medium produced greater increases in the synchronicity of transmitter quantum release in the distal parts of the synapse than in the proximal parts. Mathematical modeling of multiple-quantum endplate currents showed that the characteristics of the kinetics of the secretion process observed here in different parts of the nerve ending represent a factor which partially compensates for the decrease in the amplitude and extending of the duration of the leading front of the multiple-quantum endplate current which are associated with the low rate of conduction of excitation across the nerve ending. The contribution of this compensation increases as the intensity of secretion of transmitter quanta increases in the distal parts of the synaptic contact.     

Double-barrelled connections between the striatum and substantia nigra in the light and electron microscopy picture in the cat]

Following coagulation of either the substantia nigra or the caudate nucleus and fundus caudati of the cat, the distribution of degenerating terminals in the sections of the striatum has been determined especially in the fundus caudati on one side and in the various cell groups of the substantia nigra compacta on the other side; and the types of synapses have been described. There are reverberating circuits between the fundus caudati and the medial groups of the nigra characterized by their small cells, between the putamen and the postero-lateral cell groups of the nigra, between the caudatum and the rostral cell groups of the nigra, presumably with the specialization that the lateral caudatum is in two-way connection with the rostro-lateral cell groups of the nigra as is the medial caudatum with the rostro-medial cell group. The transmitter for the striatofugal terminals in the nigra which have pleomorphic synapses is probably GABA. Dopamine is the transmitter of the axo-spinous synapses of the nigrostriatal neurons with the small striatal nerve cells for which the transmitter seems to be Acetylcholine. The nigro-striatal reverberating circuits have three outputs available; 1. from parts of the striatum to the entopeduncular nucleus (internal segment of pallidum) and from there through the H2 and H1 fields of Forel to the oral ventral nucleus of the thalamus (V.o.a) which directly projects to the area 6 a alpha of motor cortex; 2. also from parts of the striatum to the pallidum (outer segment) and continuing through the descending pallido-reticulospinal pathway and 3. from the postero-lateral cell groups of the nigra probably through descending fibers which cross the midline in the commissura colliculi superioris and extend through the reticular formation directly or indirectly to the spinal cord.
