  1. Local and commissural IC neurons make axosomatic inputs on large GABAergic tectothalamic neurons.

    Journal of Comparative Neurology 522(15):3539 (2014) PMID 24796971 PMCID PMC4139440

    We tested the hypothesis that these excitatory, glutamatergic axosomatic inputs on LG neurons come from local axonal collaterals and commissural IC neurons. We injected a recombinant viral tracer into the IC which enabled Golgi-like green fluorescent protein (GFP) labeling in both dendrites and axon...
  2. Adenosine triphosphate-induced photoreceptor death and retinal remodeling in rats.

    Journal of Comparative Neurology 522(13):2928 (2014) PMID 24639102

    Many common causes of blindness involve the death of retinal photoreceptors, followed by progressive inner retinal cell remodeling. For an inducible model of retinal degeneration to be useful, it must recapitulate these changes. Intravitreal administration of adenosine triphosphate (ATP) has recentl...
  3. Large basolateral processes on type II hair cells are novel processing units in mammalian vestibular organs.

    Journal of Comparative Neurology 522(14):3141 (2014) PMID 24825750 PMCID PMC4107051

    We describe unique morphological features of type II vestibular hair cells in mature rodents (mice and gerbils) and bats. These features are cytoplasmic processes that extend laterally from the hair cell base and project under type I hair cells. Closer analysis of adult mouse utricles demonstrated t...
  4. The insular auditory field receives input from the lemniscal subdivision of the auditory thalamus in mice.

    Journal of Comparative Neurology 522(6):1373 (2014) PMID 24638871

    We studied the auditory thalamic input to the insular cortex using mice as a model system. An insular auditory field (IAF) has recently been identified in mice. By using retrograde neuronal tracing, we identified auditory thalamic neurons projecting to the IAF, primary auditory cortex (AI), and ante...
  5. The cross-modal aspect of mouse visual cortex plasticity induced by monocular enucleation is age dependent.

    Journal of Comparative Neurology 522(4):950 (2014) PMID 24037705

    We specifically investigated the age dependence of the onset and the exact timing of both ME-induced reactivation processes by comparing cortical activity patterns of mice enucleated at postnatal day (P) 45, 90, or 120. A swifter open-eye potentiated reactivation characterized the binocular visual c...
  6. Neuropeptides in the antennal lobe of the yellow fever mosquito, Aedes aegypti.

    Journal of Comparative Neurology 522(3):592 (2014) PMID 23897410

    We analyzed neuropeptides in the antennal lobe of the yellow fever mosquito, Aedes aegypti, a major vector of arboviral diseases. Direct tissue profiling of the antennal lobe by matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectrometry indicated the presence of 28 matu...
  7. Visual pigments and opsin expression in the juveniles of three species of fish (rainbow trout, zebrafish, and killifish) following prolonged...

    Journal of Comparative Neurology 522(1):98 (2014) PMID 23818308

    We investigate the action of TH and RA on single-cone opsin expression in juvenile rainbow trout, zebrafish, and killifish and on the absorbance of visual pigments in rainbow trout and zebrafish. Prolonged TH exposure increased the wavelength of maximum absorbance (λmax ) of the rod and the medium (...
  8. Cholinergic circuitry of the human nucleus basalis and its fate in Alzheimer's disease.

    Journal of Comparative Neurology 521(18):4124 (2013) PMID 23852922

    The nucleus basalis is located at the confluence of the limbic and reticular activating systems. It receives dopaminergic input from the ventral tegmental area/substantia nigra, serotonergic input from the raphe nuclei, and noradrenergic input from the nucleus locus coeruleus. Its cholinergic contin...
  9. Alzheimer's disease pathology in the neocortex and hippocampus of the western lowland gorilla (Gorilla gorilla gorilla).

    Journal of Comparative Neurology 521(18):4318 (2013) PMID 23881733

    We examined Aβ and tau-like lesions in the neocortex and hippocampus of aged male and female western lowland gorillas using immunohistochemistry and histochemistry. Analysis revealed an age-related increase in Aβ-immunoreactive plaques and vasculature in the gorilla brain. Aβ plaques were more abund...
  10. Migration of bone marrow-derived cells into the central nervous system in models of neurodegeneration.

    Journal of Comparative Neurology 521(17):3863 (2013) PMID 23682015

    Microglia are the brain-resident macrophages tasked with the defense and maintenance of the central nervous system (CNS). The hematopoietic origin of microglia has warranted a therapeutic potential for the hematopoietic system in treating diseases of the CNS. However, migration of bone marrow-derive...
