A clear, journalistic exploration of why scientists and philosophers disagree about machine consciousness, what criteria matter, and why the debate is so hard to resolve.
Link to paper
Organizes the major theoretical approaches to machine consciousness into a structured taxonomy, clarifying distinctions between access, phenomenology, and functional architectures.
Link to paper
A rigorous critique arguing that current AI systems do not meet philosophical or scientific criteria for consciousness, outlining what would be required for a true artificial mind.
Link to paper

Proposes concrete architectures and design principles for building systems that might satisfy proposed criteria for consciousness, bridging abstract theories with implementation.
Link to paper
Argues that sufficiently advanced AI systems may be impossible to fully control or contain, introducing computability limits that inform debates about machine consciousness and safety.
Link to paper
Explores how even potential indicators of consciousness in AI systems reshape our ethical responsibilities and influence design, oversight, and governance frameworks.
Link to paper

Develops a framework for defining, evaluating, and applying “indicators of consciousness” to artificial agents, usable across multiple theories of mind.
Link to paper
Extends the classical Turing Test into a bilateral assessment where both machine and human can query each other, creating a more nuanced experimental probe of machine-like experience.
Link to paper
Integrates deep learning models, neuroscience, and phenomenological reports to computationally investigate the mechanisms underlying experience, both human and artificial.
Link to paper

Introduces the “hard problem” of consciousness, distinguishing physical explanations from subjective experience.
Link to paper
A landmark argument showing why subjective experience cannot be reduced to objective physical facts.
Link to paper
Proposes that consciousness may be a fundamental feature of the universe, outlining several non-reductive frameworks.
Link to paper

Explores how conscious perception of time can transform during a single perceptual switch, offering insights into subjective temporality.
Link to paper
Examines how psychedelics disrupt the sense of self and what this reveals about the structure of consciousness.
Link to paper
Analyzes altered states during near-death episodes, offering models that map phenomenology onto neural dynamics.
Link to paper

Proposes integrating first-person phenomenology with neuroscience to bridge subjective and objective accounts of consciousness.
Link to paper

Personalized medicine is transforming neuroscience and psychiatry by tailoring interventions to an individual’s genetic profile, neural architecture, and cognitive patterns. These approaches aim to optimize treatment efficacy, reduce side effects, and address the unique biological and psychological factors underlying brain disorders. By integrating genomics, neuroimaging, and AI-driven data analysis, personalized neuroscience promises a new era of targeted, patient-centered care.

New framework for the diagnosis and treatment of psychiatric disorders, incorporating symptoms, biological, and behavioral information.

Investment in brain computer interface (BCI) technologies is rapidly accelerating. This surge reflects growing confidence that BCIs are transitioning from experimental research tools into scalable, real-world wearable technologies to better understand brain health, treat neurological diseases, and beyond.

Founder and CEO of Anthropic outlines the future of a world with powerful AI and its potential in revolutionizing governments, health, and innovation.

Psychedelic-assisted therapy has emerged as a rapidly growing area of psychiatric research, driven by promising evidence for treating conditions such as depression, PTSD, anxiety, and addiction. Previously stigmatized in Western medicine, these interventions are now being rigorously studied within controlled clinical frameworks, combining pharmacology with psychotherapy to leverage altered states of consciousness for therapeutic benefit. Active research efforts include the US Veteran Affairs Department and large academic institutions.
