Orbitofrontal neurons signal reward predictions, not reward prediction errors

Orbitofrontal neurons signal reward predictions, not reward prediction errors. Stalnaker, T., Liu, T., Takahashi, Y., & ... Neurobiology of learning …, Elsevier, 2018.

Paper abstract bibtex

Neurons in the orbitofrontal cortex (OFC) fire in anticipation of and during rewards. Such firing has been suggested to encode reward predictions and to account in some way for the role of this area in adaptive behavior and learning. However, it has also been reported that neural activity in OFC reflects reward prediction errors, which might drive learning directly. Here we tested this question by analyzing the firing of OFC neurons recorded in an odor discrimination task in which rats were trained to sample odor cues and respond left or right …
