For #FluorescenceFriday beautiful Suprachiasmatic hypothalamic nuclei injected with AAV-Channelrhodopsin2-YFP in AVP-Cre rats with Vasopressin peptide in red (and magenta in the confocal image down right). My (failed) attempt to get a cover image 🧠🔬😜

Key point: Optogenetic stimulation of dentate gyrus granule cells leads to strong synaptic activation of mossy cells.
