Different brain systems support the aversive and appetitive sides of human pain-avoidance learning

The paper investigates whether aversive and appetitive pain-avoidance learning use shared or separate systems, finding distinct neural pathways and dopaminergic/opioid regulation.

Effect sizes and test-retest reliability of the fMRI-based Neurologic Pain Signature

The paper evaluates the effect size and test-retest reliability of the Neurologic Pain Signature (NPS) across multiple studies, finding large within-person effect sizes and reliable performance with sufficient trial numbers.

Uncertainty-driven regulation of learning and exploration in adolescents: A computational account

This study compares how adolescents and adults adjust learning rates and exploration based on uncertainty over time, finding adolescents overestimate environmental volatility leading to higher learning rates and exploration.

Evoked pain intensity representation is distributed across brain systems: A multistudy mega-analysis

This study investigates the spatial scale of acute pain representation using fMRI data from 289 participants, finding that distributed, multi-system models better capture pain intensity than single regions or networks.
