Shown are regenerating dendrites and uninjured dendrites of PVD neurons in C. elegans.

To assess neural activity during mouse tasting behavior, a calcium indicator (green) and a red fluorescent protein (magenta) were expressed in the locus coeruleus.

Pictured are proprioceptive sensory afferents and Atoh1-lineage neurons in the lower thoracic mouse spinal cord.

Reconstructed 3-dimensional whole brain distribution of orexin receptor expression visualized using the branched hybridization chain reaction method.

Two images of tree shrew retina captured with in vivo optical coherence tomography and ex vivo confocal imaging reveal densely packed, vertically elongated, and stratified axon bundles that are more like axon bundles in humans than in mice.

A maximum intensity projection image of a sagittal mouse brain slice captured using confocal microscopy.

This image shows the cellular layers of an adult mouse retina, stained for markers of amacrine cells and type 3b bipolar cells.

Confocal image of the hippocampus showing somatostatin inhibitory neurons (green).

This image shows 3D reconstructions of Little skate photoreceptor terminals (orange) and postsynaptic partners (yellow and blue) obtained from serial block-face electron microscopy data.

Confocal image of a brain section containing the somatosensory (barrel) cortex from a transgenic mouse.
