Brain Activation During The Decision Phase Intertemporal Choice Additionally, we wanted to test whether adults and adolescents show differences in brain response during the decision processing phase in intertemporal choice (q3) and whether the consistency of choices is related to brain activity during the decision making phase in general (q4). This raises the intriguing question of which subjective value function is represented in the brain. a second factor that may account for patterns of activation in mpfc, pcc, and vs during intertemporal choice is stimulus type, in particular the presence or absence of an option to receive an immediate reward.
Brain Activation During The Decision Phase Intertemporal Choice With regard to the neural correlates, choice related activation during both the absence and presence of time ambiguity was found in a network of brain regions commonly associated with intertemporal choices and decision making (bartra et al., 2013; kable and glimcher, 2007; mcclure et al., 2004). | brain activation during the decision phase (intertemporal choice task). (a): reward decision phase > implicit baseline (b): loss decision phase > implicit baseline. results displayed at p < 0.5. We employed independent component analysis (ica) to identify large scale neural networks engaged during intertemporal choice and tested the relationship between component activation and individual differences in choice behavior. Recent neuroimaging studies suggest that the subjective value of available rewards con tributes to activation in mpfc, pcc, and vs during inter temporal choice. kable and glimcher [2007] presented participants with a choice between an immediate reward fixed in magnitude and a delayed reward whose magnitude and delay were parametrically varied.

Additionally, we examined how brain activation in response to risky and intertemporal choice relates to the risk and time preferences of individual subjects: were there regions whose activation predicted whether particular individuals made risk seeking averse or delay seeking averse choices?. In conclusion, delayed rewards activated the cold brain regions, while immediate rewards activated the hot brain regions during intertemporal decision making. cognition and emotion related networks regulated activation during risky reward choices.
