| topographic distribution of efferent fibers originating from homotopic or heterotopic transplants: heterotopically transplanted neurons retain some of the developmental characteristics corresponding to their site of origin. | the present study was undertaken to determine whether the topographical distribution of cortical efferents is exclusively dependent on environmental cues or is also controlled by intrinsic factors. for the purpose, we used a sensitive tract-tracing method (phaseolus vulgaris leucoagglutinin) to compare the pattern of efferent fibers of homotopic and heterotopic transplants of embryonic (e16) neocortex. our findings indicate that transplants of embryonic sensorimotor cortex placed homotopically i ... | 1994 | 7513624 |
| multiple anterograde tracing, combining phaseolus vulgaris leucoagglutinin with rhodamine- and biotin-conjugated dextran amine. | the simultaneous use of different neuroanatomical anterograde tracers provides a potentially powerful method to study the convergence of afferent systems in a particular brain area. however, a simple routine procedure to apply multiple anterograde tracers in conjunction with their simultaneous visualization is still missing. we report an easy and straightforward application of three sensitive anterograde tracers: phaseolus vulgaris leucoagglutinin (pha-l), rhodamine-conjugated dextran amine (rda ... | 1994 | 7514701 |
| organization of the efferent projections from the pontine parabrachial area to the bed nucleus of the stria terminalis and neighboring regions: a pha-l study in the rat. | the organization of efferent projections from the pontine parabrachial (ppb) area to the forebrain rostral to the central nucleus of the amygdala (ce) was studied in the rat by using microinjections of phaseolus vulgaris leucoagglutinin (pha-l), into subregions of the ppb area. the present study is a follow-up of a former study (bernard et al. [1993] j. comp. neurol. 329:201-229) which examines ppb projections onto the ce. the results demonstrate that: (1) the ppb(m) region (the medial, the vent ... | 1994 | 7515078 |

| reciprocal connections of lateral septal neurons and neurons in the lateral hypothalamus in the rat: a combined phaseolus vulgaris-leucoagglutinin and fluoro-gold immunocytochemical study. | reciprocal connections between lateral septal neurons and neurons in the lateral hypothalamus/lateral preoptic area were studied in the rat. the anterograde tracer phaseolus vulgaris leucoagglutinin (pha-l) and the retrograde tracer fluoro-gold (fg) were simultaneously injected into the lateral septum. after double-immunocytochemistry, pha-l-labeled terminals were found in synaptic contact with dendrites of retrogradely fg-labeled neurons in the lateral hypothalamic/lateral preoptic area. | 1994 | 7518057 |
| cytochemical staining for beta 1,6 branching of asparagine-linked oligosaccharides in variants of metastatic human colon carcinoma cells. | a positive correlation between tumor progression in human colon and increased beta 1,6 branching in oligosaccharides has recently been demonstrated. the present study was undertaken to elucidate whether such a correlation can be extended to variants of metastasizing human colon carcinoma hct116 cells. the phaseolus vulgaris leukoagglutinating lectin, which binds to beta 1,6 branched oligosaccharides, was employed. in blots, a band of approximately 140 kd was detectable in both the hct116a and hc ... | 1994 | 7519829 |
| cholecystokinin corticostriatal pathway in the rat: evidence for bilateral origin from medial prefrontal cortical areas. | the anterograde tracer phaseolus vulgaris-leucoagglutinin was used to examine the organization of the projections to the striatum from medial prefrontal and frontal cortical areas in the rat with reference to their relation to cholecystokinin-like immunoreactivity in the striatum. medial prefrontal cortical areas projected bilaterally, with an ipsilateral predominance, to the striatum. most of the positive fibres were found in medial and ventral areas of the caudate-putamen and in the nucleus ac ... | 1994 | 7520138 |
| gabaergic projection from the intercalated cell masses of the amygdala to the basal forebrain in cats. | the intercalated cell masses (icms) are dense clusters of small gabaergic cells interposed between the basolateral and centromedial nuclear groups of the amygdala. until now, the icms have been largely ignored in anatomical studies of the amygdaloid complex. thus, this study was undertaken to identify some of their targets by means of tract-tracing methods combined with immunohistochemical techniques. wheat-germ agglutinin conjugated to horseradish peroxidase (wga-hrp) was injected into numerous ... | 1994 | 7520456 |
| input-output organization of the rat vibrissal motor cortex. | the afferent and efferent connections of the vibrissal area of the rat motor cortex (vmcx) were investigated by injecting phaseolus vulgaris leucoagglutinin (pha-l) or wheat germ agglutinin-horseradish peroxidase into the physiologically defined vmcx. the vmcx formed reciprocal connections with the primary and secondary somatosensory cortex, lateral and ventrolateral orbital cortex, retrosplenial cortex, and perirhinal cortex. these corticocortical afferents originated from cell bodies in layers ... | 1994 | 7523173 |
| commissural connections of the cat periaqueductal gray matter studied with anterograde and retrograde tract-tracing techniques. | the commissural connections of the periaqueductal gray matter were investigated by light and electron microscopy by using the anterograde tracer phaseolus vulgaris leucoagglutinin and the retrograde tracer horseradish peroxidase. in the first group of seven animals (1-7), single injections of phaseolus vulgaris leucoagglutinin were performed iontophoretically (4.5 microa for 30 min) into various subdivisions of the periaqueductal gray matter. on light microscopic examination, injection sites wer ... | 1994 | 7523986 |
| organization of vestibular inputs to nucleus tractus solitarius and adjacent structures in cat brain stem. | the vestibular system is involved in maintaining stable blood pressure and respiration during changes in posture and is essential for eliciting motion sickness-related vomiting. because the nucleus tractus solitarius (nts) participates in the regulation of sympathetic and inspiratory outflow and the triggering of emesis, we tested the hypothesis that this region receives vestibular inputs in cats. in one set of experiments, microinjections of the tracer phaseolus vulgaris leucoagglutinin into th ... | 1994 | 7524372 |
| projections of the suprachiasmatic nuclei, subparaventricular zone and retrochiasmatic area in the golden hamster. | the patterns of projections from the hamster suprachiasmatic nucleus, retrochiasmatic area and subpraventricular hypothalamic zone were examined using anterograde tracing with the plant lectin, phaseolus vulgaris leucoagglutinin. suprachiasmatic nucleus efferents comprise four major fiber groups: (i) an anterior projection to the ventral lateral septum, the bed nucleus of the stria terminalis and anterior paraventricular thalmus; (ii) a periventricular hypothalamic projection extending from the ... | 1994 | 7526267 |
| projections from the primary auditory cortex onto the dorsal cortex of the inferior colliculus in albino rats. | the topography of connections from the primary auditory cortex (te1) onto the dorsal cortex (dc) of the inferior colliculus (ic) was studied using the anterograde neural tracers phaseolus vulgaris (pha-l) and biotinylated dextran amine (bda). injections in different restricted portions of the ventral te1 showed labelled axonal sheets in the ipsilateral dc with extensions in the central nucleus and the external cortex. also contralateral labelled axons were found with a patchy appearance. the pat ... | 1994 | 7526815 |
| em study on terminals labelled by phaseolus vulgaris lectin in ectostriatum periphericum and neostriatum intermedium. | the terminals of rotundal fibers labelled with phaseolus lectin anterograde tracer were studied in ectostriatum periphericum and neostriatum intermedium laterale with em. these terminals belong to the fibers which cross the ectostriatum centrale before they enter the ectostriatum periphericum and neostriatum intermedium laterale. these terminals establish synapses with dendrites, spines and also with gaba immunogold stained somata. the em results prove the connections of ectostriatum periphericu ... | 1994 | 7527065 |
| preoptic projections to barrington's nucleus and the pericoerulear region: architecture and terminal organization. | the medial preoptic area (mpo), a sexually dimorphic region, plays a pivotal role in neuroendocrine function and reproductive behavior. we recently reported that mpo projects heavily to the midbrain periaqueductal gray (pag). we also noted that mpo projects to the dorsolateral pontine tegmentum. here we identified the cells of origin of the mpo-->tegmental projection and delineated the terminal organization of mpo projections to barrington's nucleus, locus coeruleus (lc), and the rostromedial pe ... | 1994 | 7528227 |
| efferent connections of the medial prefrontal cortex in the rabbit. | the different cytoarchitectonic regions of the medial prefrontal cortex (mpfc) have recently been shown to play divergent roles in associative learning in rabbits. to determine if these subareas of the mpfc, including areas 24 (anterior cingulate cortex), 25 (infralimbic cortex), and 32 (prelimbic cortex) have differential efferent connections with other cortical and subcortical areas in the rabbit, anterograde and retrograde tracing experiments were performed using the phaseolus vulgaris leukoa ... | 1994 | 7529194 |
| a direct pretectosuprachiasmatic projection in the rat. | the major afferent projections of the suprachiasmatic nuclei originate in the retina and the intergeniculate leaflet of the lateral geniculate nucleus and are important in the entrainment of endogenous circadian rhythms. a characteristic feature of the suprachiasmatic nucleus and the intergeniculate leaflet of the thalamus is that they are bilaterally innervated from the retina. however, parts of the olivary and posterior pretectal nuclei have been shown to be bilaterally innervated from the ret ... | 1994 | 7530345 |
| principal cells are the postsynaptic targets of supramammillary afferents in the hippocampus of the rat. | neurons of the supramammillary nucleus are known to fire phase-locked to hippocampal theta rhythm. stimulation of this area induces theta activity in the hippocampus via the medial septum and facilitates perforant pathway stimulation-evoked population spikes in the dentate gyrus even if the medial septum is inactivated. this latter effect was suggested to be due to a direct inhibitory input from the supramammilary nucleus to hippocampal nonpyramidal cells resulting in disinhibition. in the prese ... | 1994 | 7531093 |
| termination pattern of medial hyperstriatum ventrale efferents in the archistriatum of the domestic chick. | the chick archistriatum receives afferents from the intermediate part of the medial hyperstriatum ventrale (imhv) and projects to the lobus parolfactorius (lpo). there is functional evidence to suggest that the imhv and the lpo are connected, but there is no anatomical evidence for a direct connection between the two structures. the aim of the current study was to characterize the termination pattern of medial hyperstriatal afferents within the archistriatum to determine whether the archistriatu ... | 1994 | 7531206 |
