New ms on trinary choices! Somewhat surprisingly, our monkeys’ choices satisfied IIA (independence of irrelevant alternatives). In OFC, decision variables were represented in the same way under trinary and under binary choices. This property implies IIA.

Neuronal Activity in Orbitofrontal Cortex during Trinary Choices under Risk
Economic choice entails computing and comparing the subjective values of different goods. Orbitofrontal cortex (OFC) is thought to contribute to both operations. However, previous work focused almost ...

Dopamine-mediated formation of a memory module in the nucleus accumbens for goal-directed navigation - Nature Neuroscience
Jung et al. show that shelter experience boosts dopamine release in the nucleus accumbens, generating a goal-location memory. Reactivating a neuronal ensemble developed from shelter experience enables...

The quest to build bionic limbs that feel like the real thing, with a sense of touch.
Through brain implants, neural interfaces and skin grafts, researchers are starting to restore sensation for paralysed or amputated limbs.

1) high LC activity facilitates cortical microarousals
2) low LC activity is required for NREMS-to-REMS transitions

Infraslow noradrenergic locus coeruleus activity fluctuations are gatekeepers of the NREM–REM sleep cycle - Nature Neuroscience
Lüthi and colleagues show that activity of the locus coeruleus (LC) is crucial for the cyclic alternation between non-rapid-eye-movement and rapid-eye-movement sleep. Stressful experiences during waki...

🤔How do humans anticipate an opponent's moves in strategic games?
Excited to share our latest work on #mentalization in strategic games.
After years of work, we've empirically validated our new model, behaviorally (N~500) and neurally (N~100) 🧠 a 🧵 (1/5)
