Study : Confocal Macroscope, U Minnesota

The brain tissue was immunofluorescently labeled to show the distribution of the neurotransmitter enkephalin (ENK), its primary cognate receptor, Delta Opioid Receptor-1 (DOR1), and substance P (SP). This high-resolution print, produced on a Dirst-Dice Lambda 131 at 63.5 m pixels, contains fine detail barely visible to the naked eye.
