K_3_01 — Machine Consciousness — Can AI Be Aware?

The question of machine consciousness — whether artificial systems can be genuinely aware rather than merely simulating awareness — stands at the intersection of philosophy of mind, neuroscience, and computer science. Jo

K_3_16 — Anesthesia and Consciousness: What Going Under Reveals

General anesthesia provides a unique experimental window into consciousness: the ability to reversibly abolish and restore awareness in a controlled clinical setting. Despite over 175 years of practice since William T.G.

K_3_08 — Intention, Volition, and Motor Consciousness

The neural basis of voluntary action and the timing of conscious intention relative to brain activity has become one of the most productive — and philosophically consequential — research programs in consciousness studies

K_3_04 — Anesthesia and Consciousness

General anesthesia — the reversible, drug-induced abolition of consciousness — is one of medicine's greatest achievements and, paradoxically, one of its least understood. Approximately 350 million surgical procedures per

Shared death experiences (SDEs) are reported phenomena in which a person who is physically healthy — typically a family member, caregiver, or bystander present at a death — describes experiencing some or all of the featu

K_4_09 — Consciousness, Virtual Reality, and Simulated Environments

Virtual reality (VR) has become one of the most powerful tools for investigating the construction of conscious experience — particularly body ownership, self-location, embodiment, spatial presence, and the boundaries of

K_2_18 — Meditation Neurophysiology

Neuroimaging studies of meditation have produced a convergent picture: focused attention practices increase prefrontal and anterior cingulate cortex activity, open monitoring practices decrease default mode network (DMN)

K_5_06 — Dreaming and Consciousness: Why We Dream

Dreaming — the experience of structured hallucinatory consciousness during sleep — is one of the most remarkable features of the human mind and a central challenge for any theory of consciousness. Every night, for a tota
