Neurons in the orbitofrontal cortex encode economic value The biological time and its oscillations gain more attention and impor- tance as these interrelations are understood.

Assad1 Source: www.nature.com/23 April 2006 http://www.nature.com/nature/journal/vaop/ncurrent/full/ nature04676.html Nature advance online publication23 April 2006 doi:10.1038/nature04676 ABSTRACT Economic choice is the behaviour observed when individuals select one among many available options. There is no intrinsically 'correct' answer: economic choice depends on subjective preferences. This behaviour is Odds and ends - themes and trends 495
Neurons in the orbitofrontal cortex encode economic value traditionally the object of economic analysis and is also of primary inter- est in psychology. However, the underlying mental processes and neu- ronal mechanisms are not well understood. Theories of human and animal choice have a cornerstone in the concept of 'value'. Consider, for example, a monkey offered one raisin versus one piece of apple: behav- ioural evidence suggests that the animal chooses by assigning values to the two options. But where and how values are represented in the brain is unclear. Here we show that, during economic choice, neurons in the orbitofrontal cortex (OFC) encode the value of offered and chosen goods. Notably, OFC neurons encode value independently of visuospatial fac- tors and motor responses. If a monkey chooses between A and B, neurons in the OFC encode the value of the two goods independently of whether A is presented on the right and B on the left, or vice versa. This trait dis- tinguishes the OFC from other brain areas in which value modulates activity related to sensory or motor processes. Our results have broad implications for possible psychological models, suggesting that economic choice is essentially choice between goods rather than choice between actions. In this framework, neurons in the OFC seem to be a good candidate network for value assignment underlying economic choice.
