Neurons in the central amygdala of a mouse marked by expression of the fluorescence protein mCherry. These neurons express the neuropeptide corticotropin-releasing factor (CRF). The body of one of the neurons is overexposed, but the synaptic spines on the dendrites are visible. Confocal microscopy image taken by Hermes Solenzol.
