1. Estudo da Expressão do Canal para Sódio Dependente de Voltagem Nav1.6 nas Células Octopus e Multipolares do PVCN no Núcleo Coclear do Sistema Auditivo
O presente trabalho teve como objetivo avaliar quais subunidades de canais para sódio voltagem dependentes estão presentes em subpopulações neuronais da região póstero-ventral do núcleo coclear (PVCN). Reações de imunofluorescência de simples ou dupla marcação em fatias parassagitais do núcleo coclear revelaram a expressão do canal Nav1.6 no se

2. Detection of synchrony in the activity of auditory nerve fibers by octopus cells of the mammalian cochlear nucleus
The anatomical and biophysical specializations of octopus cells allow them to detect the coincident firing of groups of auditory nerve fibers and to convey the precise timing of that coincidence to their targets. Octopus cells occupy a sharply defined region of the most caudal and dorsal part of the mammalian ventral cochlear nucleus. The dendrites of o

3. Electrophysiological Properties of Octopus Neurons of the Cat Cochlear Nucleus: an In Vitro Study
Electrophysiological studies from mice in vitro have suggested that octopus cells of the mammalian ventral cochlear nucleus (VCN) are anatomically and biophysically specialized for detecting the coincident firing of a population of auditory nerve fibers. Recordings from cats in vivo have shown that octopus cells fire rapidly and with exceptional temporal pre

4. Light-induced motility of thermophilic Synechococcus isolates from Octopus Spring, Yellowstone National Park.
This study demonstrates light-induced motility of two thermophilic Synechococcus isolates that are morphologically similar but that belong to different cyanobacterial lineages. Both isolates migrated away from densely inoculated streaks to form fingerlike projections extending toward or away from the light source, depending on the light intensity. However, t

5. Thermocrinis ruber gen. nov., sp. nov., a Pink-Filament-Forming Hyperthermophilic Bacterium Isolated from Yellowstone National Park
A novel hyperthermophilic bacterium was isolated from pink filamentous streamers (pink filaments) occurring in the upper outflow channel (temperature, 82 to 88°C) of Octopus Spring in Yellowstone National Park, Wyo. The gram-negative cells grew at low salinity at temperatures up to 89°C in the neutral to alkaline pH range. Depending on the culture conditio

6. Cultivation of aerobic chemoorganotrophic proteobacteria and gram-positive bacteria from a hot spring microbial mat.
The diversity of aerobic chemoorganotrophic bacteria inhabiting the Octopus Spring cyanobacterial mat community (Yellowstone National Park) was examined by using serial-dilution enrichment culture and a variety of enrichment conditions to cultivate the numerically significant microbial populations. The most abundant bacterial populations cultivated from dilu

7. Denaturing gradient gel electrophoresis used to monitor the enrichment culture of aerobic chemoorganotrophic bacteria from a hot spring cyanobacterial mat.
Previous studies investigating microbial diversity in the Octopus Spring cyanobacterial mat community (Yellowstone National Park) have shown a discrepancy between bacterial populations observed by molecular retrieval and cultivation techniques. To investigate how selective enrichment culture techniques affect species composition, we used denaturing gradient
