Single neurons in the human substantia nigra encode social learning signals

Arianna N. Davis, Ofer Perl, Brian H. Kopell, Matthew Heflin, Qi Xiu Fu, Salman E. Qasim, Zarghona Imtiaz, Ayaka Kato, Soojung Na, Navid Mikail, Helen S. Mayberg, P. Read Montague, Ignacio Saez, Xiaosi Gu

The paper records single neuron activity in the substantia nigra during social learning tasks and finds dopaminergic neurons encode norm prediction error valence more strongly during human vs computer interactions.
