Principal neuron dendrites in the adult mouse olfactory bulb extending up towards the glomerular layer where they receive sensory input.

Coronal section of a mouse nucleus accumbens with GABAergic neurons ablated.

Sagittal mouse brain sections showing cerebellar nuclei sending afferents to the ventral posterolateral nucleus of the thalamus.

Cocultured human induced pluripotent stem cell-derived astrocytes and neurons.

These partial 3D reconstructions of synapses from wild-type and synapsin knock-out mice show the presynaptic membrane, the postsynaptic membrane, and synaptic vesicles.

Shown are olfactory sensory neurons, sustentacular cells, and scattered sustentacular cells and macrophages infected with SARS-CoV-2.

Visible in this sagittal section of a mouse cerebellum are granule cells and Purkinje cells.

Magenta GFAP staining shows that mouse hippocampal astrocytes have a typical swept-spider morphology, while radial glial cells extend radially through the granule cell layer.

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.
