4/4 We showed that a negative coupling between Hb and VTA when encoding NPE, which is associated with a negative learning bias. These interactions, in turn, could affect downstream NAcc responses to NPE. Structural equation modeling suggested that Hb drives activities in this network encoding NPE.

3/4 We then examine how a priori regions in a reward circuit, including habenula(Hb), ventral tegmental area(VTA), nucleus accumbens(NAcc), and ventral medial prefrontal cortex (vmPFC), encode positive and negative reward prediction errors (PPE & NPE). We showed Hb encodes NPE while VTA encodes PPE.

2/4 We showed that negative learning bias derived by a 2 learning-rate Rescorla-Wagner model captured pro-variance bias (PVB, a manifest of risk-seeking behaviour qualified using our novel reinforcement learning task). Negative learning bias & PVB are associated with anxiety and depression scores.

MEG Nord topics span perception, cognition, brain development, disorders, and quantum sensors. Abstract/reg deadline will be October 30, 2025.
We expect to have a few travel grants available for early career researchers travelling from Europe who submit an abstract or are invited for a talk! 🧠📈
