Synaptic pattern of AMPA receptor subtypes upon direction-selective retinal ganglion cells.

In the search for anisotropies that might contribute to a directional preference of direction-selective (DS) retinal ganglion cells (RGCs), we studied the distributions of AMPA receptor subtypes GluR1, GluR2/3, and GluR4 upon the dendritic arbors of DS RGCs of the rabbit with antibody immunocytochemistry. DS RGCs were injected with Lucifer yellow and the cells were identified by their characteristic morphology. The double-labeled images of dendrites and receptors were visualized by confocal microscopy and were reconstructed from high-resolution confocal images.

The distribution and morphology of calbindin D28K- and calretinin-immunoreactive neurons in the visual cortex of mouse.

We studied the distribution and morphology of calbindin D28K- and calretinin-immunoreactive (IR) neurons in the mouse visual cortex with immunocytochemistry. Most of the calbindin D28K-IR neurons were located in layers II/III and V, while calretinin-IR neurons were predominantly located in layers II/III. The labeled neurons showed variations in morphology.
