The medial (M) an posteromedial cortical (C3) amygdaloid nuclei and the nucleus of the accessory olfactory tract (NAOT) are designated the "vomeronasal amygdala" because they are the only components of the amygdala to receive a direct projection from the accessory olfactory bulb (AOB). The efferents of M and C3 were traced after injections of 3H-proline(More)
The anterior cortical (C1) and posterolateral cortical (C2) nuclei of the amygdala are designated the "olfactory amygdala" because they each receive direct projections from the main olfactory bulb. The efferents of these nuclei were traced after stereotaxic placement of 1-5 muCi tritiated proline in the corticomedial amygdala of the male golden hamsters.(More)
The efferent neurons of the gerbil vestibular system were investigated by retrograde tracing techniques and cytochemical staining for acetylcholinesterase (AChE), choline acetyltransferase (ChAT) and a number of peptides. The location, bilateral distribution, cell area and number of neurons in two identified groups of retrogradely labelled cells were(More)
The central distribution of afferents that innervate the macula of the saccule and the crista of the posterior canal was assessed in the gerbil following the direct injection of horseradish peroxidase (HRP) separately into the sensory neuroepithelia of each peripheral receptor organ. Ganglion cells innervating the posterior canal were located in the caudal(More)
In this study, we tested the hypothesis that chronic administration of phencyclidine (PCP), an N-methyl-D-aspartate (NMDA) receptor antagonist, would cause a long-lasting behavioral sensitization associated with neuronal toxicity. Female Sprague-Dawley rats were administered PCP (20 mg/kg, i.p.) once a day for 5 days, withdrawn for 72 hr, placed in(More)
The projections of the saccule, an otolith end organ, to the cochlear nuclei were studied using both transganglionic transport and intracellular injection techniques. Labeled fibers and terminals were observed in the anterior and posterior portions of the ventral cochlear nucleus and the dorsal cochlear nucleus. Most terminals were present in the granule(More)
The central projections of primary afferent fibers in the utricular nerve, which convey linear head acceleration signals to neurons in the brainstem and cerebellum, are not completely defined. The purpose of this investigation was twofold: 1) to define the central projections of the gerbil utricular afferents by injecting horseradish peroxidase (HRP) and(More)
Vestibular afferents have different physiological properties that can be at least partially correlated with the morphology that the peripheral ending makes with type I and type II hair cells. If the location of the ending in the sensory epithelium is included, the correlations are further improved. It is also known that vestibular afferents can be(More)
We wished to determine whether calbindin and/or calretinin are appropriate markers for vestibular afferents, a population of neurons in the vestibular nuclear complex, or cerebellar Purkinje inputs. To accomplish this goal, immunocytochemical staining was observed in gerbils after lesions of the vestibular nerve central to the ganglion, the cerebellum, or(More)
The numbers of supporting cells and the numbers and types of hair cells in three distinct longitudinal regions through the posterior canal cristae of control and streptomycin-treated pigeons were determined using stereological techniques. For control cristae, type I (3758) and type II (3517) hair cells occurred in approximately equal numbers. However, the(More)
