Neurons in the orbitofrontal cortex encode economic value Camillo Padoa-Schioppa & John A. Assad Nature. 2006 May 11;441(7090):223-6. Background: Pick one Introduction • How does one choose among objects is still a question. – Economics value/utilities – Mechanism of value assignment and the subsequent work of integrating and comparison – Neuron activities related to values of actions Major Finding • Able to identify neurons of rhesus monkey in – Encoding values of offered choices – Encoding values of chosen objects – Encoding the attributes (tastes) of objects (juices) Experiment Process Results Encoding the chosen values Offered values and taste • Remarks – Independent of visuomotor contingencies of the task – Independent of the specifics of the good (juice type, amounts) • Cardinal vs. Ordinal utility
