This chapter explains how high-density and high-resolution EEG (hdEEG) can provide a much more precise view of sleep neurophysiology by combining dense whole-head electrode sampling with anatomically accurate electrical source localization. The chapter concludes that anatomically accurate high-resolution EEG and source analysis could reveal previously hidden mechanisms of sleep and become increasingly important for understanding memory, emotional regulation, sleep disorders, and brain physiology.

This review proposes a developmental framework linking early brain formation, neural plasticity, and memory consolidation. The authors trace neural organization from embryonic morphogenesis through fetal activity-dependent synaptogenesis and infant memory development.
Overall, the paper emphasizes continuity between early developmental brain activity, neural plasticity, and later cognitive function. Read Full Article »

This paper proposes a theoretical model of how the limbic system regulates large-scale cortical networks through two complementary control mechanisms. Overall, the paper suggests that dual limbic control provides a common framework for understanding attention, motivation, memory, cognition, and behavior, with the dorsal system emphasizing internally generated expectations and the ventral system emphasizing environmental constraints.

This chapter examines how the brain transforms deliberate learning into rapid, automatic performance, using quarterbacks learning to recognize defensive formations as an example. The authors emphasize that sleep—particularly slow-wave sleep and sleep spindles—is essential for consolidating newly learned skills and memories. They propose that dEEG and fMRI could eventually be used to monitor learning and develop individualized interventions to optimize performance. Read Full Paper»

This study evaluated whether high-density EEG (HD-EEG) source imaging can accurately localize the brain region where epileptic seizures begin. The study demonstrates that HD-EEG source imaging can provide a noninvasive, high-resolution method for identifying seizure-onset regions, potentially complementing invasive recordings and helping guide surgical evaluation.

This study investigated whether slow-pulsed transcranial electrical stimulation (TES) could safely suppress epileptic brain activity in seven adults with drug-resistant epilepsy. The findings provide preliminary evidence that patient-specific HD-EEG source localization combined with focal TES can safely reduce cortical excitability. Read Full Paper»

This study investigated how the brain uses multiple memory systems during category learning, and how their involvement changes over time. Overall, the study demonstrates that learning is not dependent on a single memory system; rather, the brain flexibly switches between memory strategies to optimize performance, with these strategies potentially becoming increasingly automatic as expertise develops.

This chapter proposes that human memory, sleep, brain development, and culture co-evolved, with cultural memory playing a central role in shaping individual and social identity. The paper presents sleep-dependent memory consolidation as a potential biological foundation for the evolution of human cognition, cultural transmission, and personal identity, while suggesting that the dissolution of traditional cultural memory may create new challenges for identity in modern society.

This paper proposes the Adaptive Bayes Process Model, a theoretical framework extending predictive coding to explain how motivation and emotion shape unconscious perception, cognition, and behavior. The authors propose that these processes extend into memory consolidation and neural development, providing a unified account of how experience shapes cognition and behavior. Read Full Paper»

The review proposes that consciousness emerges from the interaction of implicit and explicit memory systems across the entire brain, rather than from the cerebral cortex alone. The authors suggest that consciousness is a continuous, dynamic process extending from unconscious contextual processing to marginal awareness and explicit focal experience, with arousal and sleep mechanisms playing a fundamental role in organizing this process.
