Mental Scene and Memory Construction and the Hippocampus

Hippocampus, Volume 36, Issue 6, November 2026.
ABSTRACT A neurocomputational theory of scene and memory construction during memory recall, prospective thinking, and autobiographical memory is described. The theory describes the nature of the representation of scenes using spatial view cells in a continuous attractor network in the medial parahippocampal cortex, and how the location in the scene ...

A Practical Guide to Optimal Adaptive Two‐Stage Designs for Various Endpoint Types

Pharmaceutical Statistics, Volume 25, Issue 6, November/December 2026.
ABSTRACT Adaptive designs are frequently used to adjust sample sizes based on interim data, ensuring reliable conclusions while protecting resources. To maximize trial efficiency, design parameters can be optimized to minimize an objective function (e.g., the expected sample size) while rigorously controlling overall error rates or further operating ...

Nucleus Accumbens and Ventral Tegmental Area Functional Connectivity as a Marker of Reward Sensitivity in Infancy

Developmental Science, Volume 29, Issue 6, November 2026.
ABSTRACT Early functional connectivity within the brain's reward circuitry may provide insight into the developmental origins of individual differences in pleasure and motivation. This study examined resting‐state functional connectivity between two key reward‐related regions, the nucleus accumbens (NAc) and ventral tegmental area (VTA), in 94 one ...

Excitation–inhibition imbalance links amyloid pathophysiology to cognition in non‐demented individuals

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Excitation–inhibition (E/I) imbalance has been proposed as an early circuit‐level mechanism in Alzheimer's disease (AD), but its relationship to molecular pathology and cognition in humans remains unclear. METHODS We integrated biophysical modeling of resting‐state functional magnetic resonance imaging with cerebrospinal fluid ...
