The distribution of premotor neurons projecting to motor nuclei of both the VIIth (VII) and XIIth (XII) nerves was examined in the pontomedullary reticular formation (RF) of the rat by using retrograde double labeling. After injection of two different tracers in the VII and the XII, most of the double labeled neurons were found caudally in the dorsal RF(More)
This study was undertaken to identify premotor neurons in the pontomedullary reticular formation serving as relay neurons between the sensory trigeminal complex and the motor nuclei of the VIIth and XIIth nerves. Trigeminoreticular projections were first investigated after injections of anterogradely transported tracers (biotinylated dextran amine,(More)
Neuroanatomical tract-tracing methods were used to study the topography of the reticulocollicular projections. Injections of gold-HRP or BDA tracers into the medial and/or central portions of the superior colliculus resulted in labelled neurones mainly in the medial reticular formation, whereas injections into the lateral portion of the superior colliculus(More)
This study was undertaken to identify premotor neurons in the nucleus tractus solitarii (NTS) serving as relay neurons between the sensory trigeminal complex (STC) and the facial motor nucleus in rats. Trigemino-solitarii connections were first investigated following injections of anterograde and/or retrograde (biotinylated dextran amine, biocytin, or(More)
The aim of this study was to investigate the inferior alveolar nerve (IAN) and chorda tympani (CT) projections onto gustatory neurons of the nucleus of the solitary tract (NST) in the rat by immunochemical and electrophysiological techniques. IAN afferents were retrogradely labeled. NST neurons were labeled either by retrograde tracer injection into the(More)
Electrical stimulation of the supraorbital nerve (SO) induces eyelid closure by activation of orbicularis oculi muscle motoneurons located in the facial motor nucleus (VII). Neurons involved in brainstem central pathways implicated in rat blink reflex were localized by analyzing c-Fos protein expression after SO stimulation in conjunction with tracing(More)
Taste and sensory information are closely associated and our electrophysiological studies showed a trigeminal modulation of gustatory neurons in the nucleus of the solitary tract (NST). Chorda tympani (CT) and lingual nerves (LN) converge centrally in the rostral subdivision of the NST in hamsters and rats. However, no study has yet revealed the details of(More)
Anterograde tracer injections in the rat sensory trigeminal complex are shown here to demonstrate projections to the contralateral facial motor (VII) and accessory abducens (VIacc) nuclei. Most of the trigeminal fibres originated within the pars oralis (5o) and contacted neurones in the medial and intermediate VII. Moderate projections from the pars(More)
Reflex blinking provides a useful experimental tool for various functional studies on the peripheral and central nervous system, yet the neuronal circuitry underlying this reflex is not precisely known. In the present study, we investigated as to whether neurons in the reticular formation and rostral cervical spinal cord (C1) may be involved in the blink(More)
Vesicular glutamate transporters (VGluts) are widely expressed in neurons of the central nervous system, where they fulfil numerous functions during glutamatergic neurotransmission. This study examines their peripheral distribution in papillae of the tongue using immunohistochemical methods. VGlut 1 was detected in basal layers of the nontaste epithelium,(More)
