Journal ArticleDOI
How do memory systems interact? Evidence from human classification learning.
TL;DR: It is suggested that memory system interactions may reflect multiple mechanisms that combine to optimize behavior based on experience that are driven by neuromodulatory systems in addition to mediation by interaction of inputs to prefrontal cortical neurons.
Journal ArticleDOI
Decreasing Ventromedial Prefrontal Cortex Activity During Sequential Risk-Taking: An fMRI Investigation of the Balloon Analog Risk Task
Tom Schonberg,Craig R. Fox,Jeanette A. Mumford,Eliza Congdon,Christopher Trepel,Russell A. Poldrack +5 more
TL;DR: Interestingly, it is found that ventromedial prefrontal cortex (vmPFC) activity decreased as participants further expanded balloons, which suggests that escalating risk-taking in the task might be perceived as exposure to increasing possible losses rather than the increasing potential total reward relative to the starting point of the trial.
Journal ArticleDOI
A Coordinate-Based Meta-Analysis of Overlaps in Regional Specialization and Functional Connectivity across Subjective Value and Default Mode Networks
TL;DR: Understanding of how subjective value (SV) is computed and represented in the brain can be synthesized with what the authors know about the DMN, mind-wandering, and self-referential processing in light of theCBMA findings.
Journal ArticleDOI
Discovering relations between mind, brain, and mental disorders using topic mapping.
Russell A. Poldrack,Jeanette A. Mumford,Tom Schonberg,Donald J. Kalar,Bishal Barman,Tal Yarkoni +5 more
TL;DR: Data mining techniques applied to a large database of neuroimaging results can be used to identify the conceptual structure of mental functions and their mapping to brain systems and this approach has the potential to discover novel endophenotypes for neuropsychiatric disorders.
Journal ArticleDOI
Changing value through cued approach: An automatic mechanism of behavior change
Tom Schonberg,Akram Bakkour,Ashleigh M. Hover,Jeanette A. Mumford,Lakshya Nagar,Jacob Perez,Russell A. Poldrack +6 more
TL;DR: The value of food items can be modulated by the concurrent presentation of an irrelevant auditory cue to which subjects must make a simple motor response (i.e., cue-approach training) and the effects of this pairing on choice lasted at least 2 months after prolonged training.
