  • Recent studies suggest that value-based choices involve communication between parietal and prefrontal cortices. Here the authors use a novel, non-invasive cortical manipulation technique to demonstrate a causal role for such communication in mediating accurate value-based, but not perceptual, choices.

  • Polanía et al. show that, similarly to sensory signals, subjective preferences guiding choice are represented by the brain in a manner that accounts for regularities of the environment, thereby optimizing use of limited neural processing resources.

  • Polanía, Nitsche and Ruff summarize the state of non-invasive brain stimulation research in humans, discuss some current debates about properties and limitations of these methods, and give recommendations for how these challenges may be addressed.

  • Brus et al. show that modulation of slow oscillatory neural activity with non-invasive electrical stimulation of the prefrontal cortex can be used to modulate top-down control and behavioural performance in non-spatial attention.

  • Maier, Raja Beharelle et al. provide a computational model of the decision process that quantifies the temporal dynamics of weighing different attributes. Their time-varying drift diffusion model reveals latent individual differences in decision-making.

  • Using modelling and experimental data, the authors provide evidence that risk aversion may arise from relative underestimation of larger monetary payoffs, a perceptual bias rooted in the noisy logarithmic coding of numerical magnitudes.
