Photoreceptive oscillators within neurons of the premammillary nucleus (PMM) and seasonal reproduction in temperate zone birds

Highlights ► Putatively photosensitive dopamine–melatonin (DA–MEL) neurons express melanopsin. ► Clock genes are rhythmically expressed in DA–MEL neurons. ► DAergic terminal from DA–MEL neurons intermingle with TSHβ cells in pars tuberalis. ► DA–MEL neurons may encode light information and regulate...
