The use of is a recently developed technique in which receptors not found in nature are produced in neurons, and these new receptors respond only to icc; vasopressin ria; a synthetic drug dreadds; a synthetic drug ddreads; oxytocin

The right answer is dreadds ; a synthetic drug.

In neuroscience, DREADD (Designer Receptor Excluded Activated by Designer Drugs) are molecular constructs based on G-protein receptors and created so as to be sensitive only to a ligand molecule that is not naturally present in the body. 'organization. This makes it possible to control temporally and spatially their activation by injecting, at the time and in the zone desired by the experimenter, the synthetic ligand, typically an N-oxide clozapine (CNO). This makes it a valuable tool for manipulating neurons in vivo in a controlled manner.
