The brain and the immune system communicate in many ways and interact directly at neuroimmune interfaces at brain borders, such as hippocampus, choroid plexus, and gateway reflexes. The first part of this review described intercellular communication (synapses, extracellular vesicles, and tunneling nanotubes) during…

This paper uses simple arguments to derive a negative conclusion: that a computer cannot be conscious. If the brain is only a neural computer, brains cannot be conscious. Consciousness implies that there is something else happening in the brain, besides computation. In a running computer, information about outside…

One might hypothesize that the concepts discussed above are also applicable to the brain from a quantum perspective. Although quantum cognition is a controversial approach to understanding consciousness, increasing evidence supports its theoretical models. Authors have written extensively about the quantum brain in…

The Nile tilapia (Oreochromis niloticus) is a cichlid species native to Africa and is widely farmed in tropical and subtropical regions around the world, making it one of the most commercially important aquaculture species. Despite its significance, there is still a lack of detailed anatomical descriptions of its…

If brain anatomy and dynamics have a complex network structure as it has become standard to posit, it is reasonable to assume that such a structure should play a key role not only in brain function but also in brain dysfunction. However, exactly how network structure is implicated in brain damage and whether at least…

This study addresses a central question in neuroscience: What is the physical nature of consciousness? Taking a neuroscientific approach, the study first establishes working definitions for its principal terms-qualia, consciousness, and information-to specify clearly the entities under investigation. It then analyzes…

Disorders of consciousness (DoC) present significant challenges in clinical neurology, particularly when caused by brainstem injury. The brainstem’s role, especially its ascending reticular activating system (ARAS), is crucial for maintaining arousal, a fundamental component of consciousness. However, the precise…

Representationalism is the theory that our conscious perception of the world is mediated by mental representations, rather than being a direct encounter with reality. In this article, we define representations in terms of a unified theory of long-term memory that incorporates both its explicit and implicit divisions.…

Traumatic brain injury (TBI) is a major global health concern and one of the leading causes of disability worldwide. Outcomes of this injury range from full recovery to lifelong cognitive, physical, and psychological impairments. Management of TBI remains challenging due to the variety of symptoms and severity, as well…

Traumatic brain injury (TBI) and the resulting brain damage and dysfunction are one of the leading causes of death for individuals under 40 worldwide. TBI can occur due to any external force causing deformation in the brain, and it involves a complicated timeline of the initial mechanical damage followed by a…

A unifying theory of both human consciousness and memory is presented that is based on neuronal microtubules (MTs) being central to both, and different populations of pyramidal cells in neocortex and hippocampus being responsible for consciousness or memory. First, two quantum theories of consciousness are…

What consciousness is, and how it relates to the body and nature at large, are among the most enduring questions in human history. Notable thinkers have long grappled with its definition, mechanisms, and purpose. In this review, we examine both historical and contemporary perspectives on consciousness across…

This editorial explores the novel The Secret of Secrets by Dan Brown as a gateway to longstanding debates in neuroscience, particularly surrounding consciousness and free will. Highlighting the novels references to real neurophotonic technologies, it examines where scientific evidence ends and speculative fiction…

Ten years ago, we published a position paper in this journal, criticizing reductionist claims of neurobiology related to mental disorders and important theoretical concepts like free will. Our interdisciplinary group of experts highlighted the need for and the challenges of integrating different approaches and system…
