🧠 New paper by Safaai et al. (2025): parietal #cortex output populations show highly structured, task-dependent population geometry. Using multi-area recordings and circuit modeling, they show that #parietal populations display organized task-related patterns rather than uniform mixed coding, and that distinct output groups shape how decisions are routed to downstream targets:

Neural mechanisms for the attention-mediated propagation of conceptual information in the human brain

How does sensory information activate and construct representations in the human brain? This study shows that a neuronal network including the prefrontal and posterior parietal cortex and the anterior insula has a key role in the translation of perceptual information to concepts, semantics, and action plans.

The parietal cortex has a causal role in ambiguity computations in humans

Humans often face the challenge of making decisions between ambiguous options. The level of ambiguity in decision-making has been linked to activity in the parietal cortex, but what is its actual role? This study uses fMRI and TMS-EEG to show that the parietal cortex is causally involved in a computational processes that underestimate uncertainty during decision-making under ambiguity.
