Subdivisions of the dorsal raphe nucleus projecting to the lateral geniculate nucleus and primary visual cortex in the Mongolian gerbilSkirmantas Janusonis
Neuroscience and Behavior Program, University of Massachusetts, Amherst, MA 01003, USA
Neuroreport 14:459-62. 2003..Since the DRN is involved in depression and other neuropsychiatric disorders, as well as is affected by many psychotropic substances, these data may help to develop new treatments and therapies targeting specific DRN subdivisions...
Diurnal variation of c-Fos expression in subdivisions of the dorsal raphe nucleus of the Mongolian gerbil (Meriones unguiculatus)S Janusonis
Neuroscience and Behavior Program, University of Massachusetts, Amherst, Massachusetts 01003, USA
J Comp Neurol 440:31-42. 2001..These results suggest that DRN subdivisions may differ functionally with regard to the diurnal cycle, and that these differences may be reflected in the activity of nonserotonergic cells in the DRN...
Statistical distribution of blood serotonin as a predictor of early autistic brain abnormalitiesSkirmantas Janusonis
Department of Neurobiology, Yale University School of Medicine, New Haven, CT 06520 8001, USA
Theor Biol Med Model 2:27. 2005..The statistical distributions of the platelet 5-HT levels in normal and autistic groups have characteristic features and may contain information about the nature of this yet unidentified factor...
Serotonergic paradoxes of autism replicated in a simple mathematical modelSkirmantas Janusonis
Department of Neurobiology, Yale University School of Medicine, P O Box 208001, New Haven, CT 06520 8001, USA
Med Hypotheses 64:742-50. 2005..While the failure of such a mechanism may lead to consistent abnormalities of synaptic transmission with no alteration of brain 5-HT levels, its effects on blood 5-HT levels may appear paradoxical...
Retinal afferents to the dorsal raphe nucleus in rats and Mongolian gerbilsK V Fite
Neuroscience and Behavior Program, University of Massachusetts, Amherst, Massachusetts 01003, USA
J Comp Neurol 414:469-84. 1999..Major differences observed in the extent and configuration of the retinal-DRN pathway may be related to the diurnal/crepuscular vs. nocturnal habits of these two species...
Topographic organization of serotonergic dorsal raphe neurons projecting to the superior colliculus in the Mongolian gerbil (Meriones unguiculatus)S Janusonis
Neuroscience and Behavior Program, University of Massachusetts, Amherst 01003, USA
J Comp Neurol 413:342-55. 1999..These results suggest that the lateral DRN and the ventromedial/interfascicular DRN may be anatomically, morphologically, and neurochemically unique subdivisions of the gerbil DRN...
Retinal projection to the dorsal raphe nucleus in the Chilean degus (Octodon degus)K V Fite
Neuroscience and Behavior Program, Tobin Hall, University of Massachusetts, Amherst, MA 01003, USA
Brain Res 895:139-45. 2001..The functional significance of the retinal-DRN pathway remains to be determined, although a variety of evidence indicates that light may directly affect the activity of neurons and serotonin levels in the DRN...
NMDAR1-like immunoreactive fibers appear in the ipsilateral optic tract during optic nerve regeneration in Rana pipiensS Janusonis
Neuroscience and Behavior Program, University of Massachusetts Amherst, 01003, USA
Neurosci Lett 236:1-4. 1997..These results suggest that NMDA receptors may be present on retinal ganglion cell axons and terminals that have been misrouted during regeneration...
Retinal ganglion cells projecting to the dorsal raphe and lateral geniculate complex in Mongolian gerbilsKatherine V Fite
Neuroscience and Behavior Program, Tobin Hall, University of Massachusetts, Amherst, MA 01003, USA
Brain Res 973:146-50. 2003..DL RGC soma diameters fell primarily within the mid-to-upper size range of all three distributions. DL RGCs may provide information to both nuclei concerning comparable aspects of light and visual stimulation via collateralized axons...
Optic afferents to the parabrachial nucleusKatherine V Fite
Neuroscience and Behavior Program, Tobin Hall, University of Massachusetts, Amherst 01003, USA
Brain Res 943:9-14. 2002..This projection appears to be a continuation of the retinal pathway that innervates the dorsal raphe nucleus in these same species...
Origin of the blood hyperserotonemia of autismSkirmantas Janusonis
Department of Psychology, University of California, Santa Barbara, CA 93106 9660, USA
Theor Biol Med Model 5:10. 2008..Its replicability suggests that many of the genes involved in autism affect a small number of biological networks. These networks may also play a role in the early development of the autistic brain...
Early serotonergic projections to Cajal-Retzius cells: relevance for cortical developmentSkirmantas Janusonis
Yale University School of Medicine, Department of Neurobiology, New Haven, Connecticut 06520 8001, USA
J Neurosci 24:1652-9. 2004....
Ontogeny of brain and blood serotonin levels in 5-HT receptor knockout mice: potential relevance to the neurobiology of autismSkirmantas Janusonis
Department of Neurobiology, Yale University School of Medicine, New Haven, Connecticut, USA
J Neurochem 99:1019-31. 2006..The results are discussed in relation to the possible role of 5-HT in the ontogeny of autism...
