Confocal micrograph showing the connections of the visual system in a four-day-old zebrafish embryo. Staining of the neurons, glia and optic nerve illustrate the connections between the retina and the...

Schwann cells in peripheral nerves secrete a layer similar to the basal lamina called the lamina externa, boundary layer, or basement membrane. In this micrograph, the lamina externa surrounds the Sc...

Electron micrograph of a nerve from the mesentery of a rat shows groups of unmyelinated axons wrapped by deeply invaginating Schwann cells in cross section. Surrounding the Schwann cell wrapping is a ...

Single computed slice through a tomographic reconstruction of a spine synapse from the molecular layer of the cerebellar cortex from tissue that was prepared from a combination of chemical fixation an...

This multi-layer image shows the spatial relationship between filamentous actin (red) and microtubule array (green) in cultured hippocampal neurons, grown for 5 days in vitro. Actin staining (with rh...
