TY - JOUR AU - Abler, Birgit AU - Herrnberger, Bärbel AU - Grön, Georg AU - Spitzer, Manfred PY - 2009 DA - 2009/12/22 TI - From uncertainty to reward: BOLD characteristics differentiate signaling pathways JO - BMC Neuroscience SP - 154 VL - 10 IS - 1 AB - Reward value and uncertainty are represented by dopamine neurons in monkeys by distinct phasic and tonic firing rates. Knowledge about the underlying differential dopaminergic pathways is crucial for a better understanding of dopamine-related processes. Using functional magnetic resonance blood-oxygen level dependent (BOLD) imaging we analyzed brain activation in 15 healthy, male subjects performing a gambling task, upon expectation of potential monetary rewards at different reward values and levels of uncertainty.
