چکیده
Value We used the following juices, listed in roughly decreasing order of preference (associated colors in parenthesis): high-sugar lemon Kool-Aid (dark yellow), grape juice (bright green), fruit punch (magenta), apple juice (diluted to 1/2 with water, dark green), cranberry juice (diluted to 1/3 or 1/4 with water, pink), water (white), milk (red), peppermint tea (bright blue), tea (light brown), low-sugar agua frescas Kool-Aid (light red), low-sugar tamarind Kool-Aid (dark brown), slightly salted water (0.60 g/l or 0.65 g/l concentration, light gray).

Orbitofrontal cortex and the computation of economic value.
Economic choice is the behavior observed when individuals select one of many available options solely based on subjective preferences. Behavioral evidence suggests that economic choice entails two mental processes: values are first assigned to the available options, and a decision is subsequently made between these values. Numerous reports show that lesions to the orbitofrontal cortex (OFC) lea...

Economic choice entails assigning values to the available options and is impaired by lesions to the orbitofrontal cortex (OFC). Recent results show that some neurons in the OFC encode the values that monkeys (Macaca mulatta) assign to different goods when they choose between them. A broad and fundamental question is how this neuronal representation of value depends on the behavioral context. He...
متن کاملContrasting reward signals in the orbitofrontal cortex and anterior cingulate cortex.
Damage to the orbitofrontal cortex (OFC) and anterior cingulate cortex (ACC) impairs decision making, but the underlying value computations that cause such impairments remain unclear. Both the OFC and ACC encode a wide variety of signals correlated with decision making. The current challenge is to determine how these two different areas support decision-making processes. Here, we review a serie...

Economic choice entails the computation and comparison of subjective values. A fundamental contribution of neuroeconomics has been to show that subjective values are represented explicitly at the neural level during choice behavior. With this result at hand, the field has increasingly focused on the difficult question of where in the brain and how exactly subjective values are compared to make ...
متن کاملOrbitofrontal Cortex Value Signals Depend on Fixation Location during Free Viewing
In the natural world, monkeys and humans judge the economic value of numerous competing stimuli by moving their gaze from one object to another, in a rapid series of eye movements. This suggests that the primate brain processes value serially, and that value-coding neurons may be modulated by changes in gaze. To test this hypothesis, we presented monkeys with value-associated visual cues and to...
متن کاملIntegration of multiple determinants in the neuronal computation of economic values.
Economic goods may vary on multiple dimensions (determinants). A central conjecture in decision neuroscience is that choices between goods are made by comparing subjective values computed through the integration of all relevant determinants. Previous work identified three groups of neurons in the orbitofrontal cortex (OFC) of monkeys engaged in economic choices: (1) offer value cells, which enc...
