A spatially-specific pattern of cortical thickness in frontal lobe predisposes to faster future amyloid accumulation in individuals with subjective cognitive decline

The paper identifies a frontal lobe cortical thickness pattern in amyloid-negative individuals that predicts faster amyloid accumulation over five years.

The Human Brain as a Dynamic Mixture of Expert Models in Video Understanding

The paper aligns video models with EEG data to understand dynamic visual processing, finding that mid-level temporally-integrative features best match posterior brain responses.

Adaptive recruitment of cortex-wide recurrence for visual object recognition

The paper tests the adaptive recurrence hypothesis by comparing fMRI and EEG responses to images recognized by humans but differing in their solvability by a feedforward deep neural network, finding that parieto-frontal networks are recruited when ventral stream processing is insufficient.

The link between gender inequality and the distribution of brain regions' relative sizes across the lifespan and the world

The paper examines how gender inequality affects brain grey matter differences between males and females across age and geography, finding a cumulative effect with age and economic factors dominating the influence.

Frequency-specific theta states in the hippocampus are linked to reconfiguration of population activity with respect to behavioural context

The paper identifies two theta oscillation states in rats during an odor-memory task and links them to changes in hippocampal population activity related to trial outcomes.
