Journal of NeuroPhilosophy

The Journal of NeuroPhilosophy (JNφphi) is pleased to present Volume 5, No. 2 (2026), bringing together a diverse collection of peer-reviewed contributions that engage with some of the most fundamental and emerging questions at the intersection of neuroscience, philosophy, consciousness studies, cognitive science, artificial intelligence, theoretical biology, and the philosophy of mind.

This issue reflects the interdisciplinary character of neurophilosophy as a field concerned not only with the biological mechanisms underlying mental phenomena, but also with the conceptual, philosophical, and theoretical questions that arise from contemporary developments in the brain sciences. The contributions included in this volume approach these questions from different methodological and intellectual perspectives, ranging from neurobiological interpretations of consciousness to philosophical analyses of mind, language, artificial intelligence, quantum approaches, embodiment, existence, and the organization of brain function.

A central theme running through several contributions is the continuing challenge of understanding consciousness and the relationship between brain activity and subjective experience. The question of how neural processes relate to conscious states remains one of the most persistent problems shared by neuroscience and philosophy. The contribution addressing human consciousness in relation to the Brain Activation State (BAS) approaches this problem by considering consciousness through the organization and activation of neural systems. Such approaches are particularly relevant to neurophilosophy because they attempt to connect descriptions of brain function with broader questions concerning conscious experience.

The issue also contains several theoretical and conceptual contributions that expand the discussion beyond conventional neurobiological models. The articles addressing substratism, symmetry in brain function, sleep and negentropy, pathological attractor states, and neurophilosophical models of mind illustrate the breadth of contemporary theoretical work in the field. Although these contributions differ substantially in their conceptual frameworks, they share an interest in identifying organizing principles that may help explain complex biological, cognitive, and mental phenomena.
