Neurofibrillar bipolar cells in the capybara retina

Visual Neuroscience, 1996
AbstractUsing a reduced-silver neurofibrillar method, we stained a population of bipolar cells in the capybara retina. These cells are distributed throughout the retina following the same topography of other retinal cell classes as the A-type horizontal cells and ganglion cells.

Bipolar cells in the zebrafish retina

Visual Neuroscience, 2010
AbstractZebrafish are an existing model for genetic and developmental studies due to their rapid external development and transparent embryos, which allow easy manipulation and observation of early developmental stages. The application of the zebrafish model to vision research has allowed for examination of retinal development and the characteristics ...

Bipolar concept for alkaline fuel cells

Journal of Power Sources, 2006
Alkaline fuel cell stacks are mostly build in monopolar configuration of the cells. At the German Aerospace Center a bipolar plate for alkaline fuel cells has been developed and characterized in a short stack. As a consequence of the sealing concept of the stack two different bipolar plate types are needed.

The population of bipolar cells in the rabbit retina

Journal of Comparative Neurology, 2004
AbstractThe population of bipolar cells in the rabbit retina was studied using Golgi impregnation and photocatalyzed filling of single cells with dihydrorhodamine, a quantitative sampling technique. The Golgi method revealed the morphology and stratification of cells in detail.

Bipolar cells of the ground squirrel retina

Journal of Comparative Neurology, 2011
AbstractParallel processing of an image projected onto the retina starts at the first synapse, the cone pedicle, and each cone feeds its light signal into a minimum of eight different bipolar cell types. Hence, the morphological classification of bipolar cells is a prerequisite for analyzing retinal circuitry.

Bipolarity of duodenal enterochromaffin cells in the rat

Cell and Tissue Research, 1987
Enterochromaffin cells of the rat duodenum have been studied immunocytochemically by use of a specific antiserum to serotonin. At the light-microscopic level serotonin immunoreactivity was observed in enterochromaffin cells located in the epithelium of the duodenal mucosa. Most of the serotonin-immunoreactive material was localized to the basal portion

Contrast processing by ON and OFF bipolar cells

Visual Neuroscience, 2010
AbstractMuch of what is currently known about the visual response of retinal bipolar cells is based on studies of rod-dominant responses to flashes in the dark in the isolated retina. This minireview summarizes quantitative findings on contrast processing in the intact light-adapted retina based on intracellular recording from more than 400 cone-driven

Types of bipolar cells in the mouse retina

Journal of Comparative Neurology, 2003
AbstractWe studied the morphology of bipolar cells in fixed vertical tissue sections (slices) of the mouse retina by injecting the cells with Lucifer Yellow and Neurobiotin. Nine different cone bipolar cell types and one rod bipolar cell type were distinguished.

The network properties of bipolar–bipolar cell coupling in the retina of teleost fishes

Visual Neuroscience, 1994
AbstractRetinal bipolar cells exhibit a center-surround antagonistic receptive field to a light stimulus (Werblin & Dowling, 1969; Kaneko, 1970), and thus constitute an early stage of spatial information processing. We injected Lucifer Yellow and a small biotinylated tracer, biocytin, into bipolar cells of the teleost retina to examine electrical ...

Monocyte-Derived Dendritic Cells in Bipolar Disorder

Biological Psychiatry, 2006
Dendritic cells (DC) are key regulators of the immune system, which is compromised in patients with bipolar disorder. We sought to study monocyte-derived DC in bipolar disorder.Monocytes purified from blood collected from DSM-IV bipolar disorder outpatients (n = 53, 12 without lithium treatment) and healthy individuals (n = 34) were differentiated into
