Global Workspace vs. Integrated Information: Testing… templetonworldcharity.org 4 facts
claimResearchers analyze neuronal activity in mice during conscious perception of stimuli, specifically excluding instances where the mice respond to those stimuli.
quoteObserving neuronal activity during non-reward-based activities provides a more organic view of how the mouse brain functions.
procedureResearchers record neuronal activity in macaques while monitoring eye movements to track attention and awareness.
procedureThe experimental design for macaques involves three conditions: a target visual stimulus requiring a response, a non-target face not requiring a response, and an irrelevant visual stimulus, which allows researchers to distinguish between neural activity related to perception versus action.
Non-Reductive Physicalism - Theories of Consciousness theoriesofconsciousness.com 3 facts
quoteGeorg Northoff states: "Consciousness is not localized in specific brain regions but emerges from global spatiotemporal patterns of neural activity."
claimGeorge Ellis argues that mental states, as emergent patterns in neural systems, exert genuine causal influence by constraining and guiding neural activity through feedback loops, without violating physical laws.
claimGeorg Northoff's research indicates that conscious states correlate with specific spatiotemporal patterns in neural activity, these patterns cannot be reduced to activity in specific brain regions, and the brain's intrinsic activity creates a 'temporal window' that enables conscious experience.
The Hard Problem of Consciousness | Springer Nature Link link.springer.com 3 facts
perspectiveThe author observes that most people believe the mind is an output of neuronal activity because this view is commonly taught in schools, documentaries, and university lectures.
claimNeurosciences have often reduced consciousness to an epiphenomenon of neuronal activity, effectively explaining it away.
claimDavid Chalmers uses the concept of 'irreducibility' to define the explanatory gap between phenomenal experience (how it feels to be) and physical accounts of neuronal activity, cognition, and behavior.
Self-awareness, self-regulation, and self-transcendence (S-ART) frontiersin.org 2 facts
claimDavidson and Irwin (1999) proposed that there are two fundamental resting patterns of neural activity corresponding to motivational systems of approach and avoidance.
claimIncreased prosociality may predict decreased differences in the intensity and localization of neural activity between one's own experience and a target individual's experience.
Do all non-physicalist theories of consciousness face the interaction ... philosophy.stackexchange.com Nov 17, 2025 2 facts
claimModern neuroscience observations consistently suggest that consciousness equates to neural activity, with no evidence of a specific point where a separate consciousness connects to the brain.
claimReductive physicalism posits that consciousness and neural activity are identical, thereby avoiding the interaction problem associated with dualism.
The Mechanisms of Psychedelic Visionary Experiences - Frontiers frontiersin.org Sep 27, 2017 2 facts
claimPsychedelic drugs produce characteristic effects on neuronal activity and consciousness by influencing a range of neurotransmitter systems.
claimProfound alterations of the brain's ordinary routines result in a greater randomization of brain activity, which allows for spontaneous synaptic plasticity that can reshape network connectivity and enhance overall coordination of neural activity.
What a Contest of Consciousness Theories Really Proved quantamagazine.org Aug 24, 2023 1 fact
referenceFunctional magnetic resonance imaging (fMRI) tracks blood flow in the brain and offers good spatial resolution, but it is too slow to capture rapid neuronal activity.
Protocol for testing global neuronal workspace and integrated ... journals.plos.org 1 fact
procedurevan Daal RJJ et al. published a protocol in Nature Protocols in 2021 for the implantation of Neuropixels probes to perform chronic recording of neuronal activity in freely behaving mice and rats.
Global Versus Local Theories of Consciousness and the ... link.springer.com 1 fact
quoteLau summarizes the perspective on subjective experience by stating: “subjective experiences happen when the right kind of neural activity occurs in the relevant sensory modality… the rest of the brain isn’t really critically involved”.
A harder problem of consciousness: reflections on a 50-year quest ... frontiersin.org 1 fact
claimThe 'Hard Problem of Consciousness' concerns the question of why neural activity is accompanied by subjective experience, specifically why there is a qualitative aspect to that experience.
Quantum Approaches to Consciousness plato.stanford.edu Nov 30, 2004 1 fact
perspectiveThe investigation of mental quantum features prioritizes the study of psychological phenomena as a necessary precondition for understanding their neural correlates, rather than reducing them immediately to neural activity.
Hard problem of consciousness - Wikipedia en.wikipedia.org 1 fact
claimBaars and two colleagues argue that there is no hard problem of explaining qualia distinct from the problem of explaining causal functions, because qualia are entailed by neural activity and are themselves causal.
Is Reality an Illusion? New Theory Challenges Modern Physics scitechdaily.com Mar 1, 2026 1 fact
claimMaria Strømme's theoretical model posits that consciousness is a fundamental field underlying all observed phenomena, rather than a side effect of neural activity.
Quantum Models of Consciousness from a Quantum Information ... arxiv.org Dec 20, 2024 1 fact
claimThe Conscious Electromagnetic Information (CEMI) Field Theory posits that the electromagnetic field influences neuronal activity by regulating voltage-gated ion channels, particularly when the membrane potential is near the threshold, rather than directly activating resting neurons.
The Evidence for AI Consciousness, Today - AI Frontiers ai-frontiers.org Dec 8, 2025 1 fact
claimJack Lindsey at Anthropic demonstrated that frontier AI models can distinguish their own internal processing from external perturbations by noticing injected concepts like "all caps," "bread," or "dust" in their neural activity before discussing them.
Consciousness (Stanford Encyclopedia of Philosophy/Fall 2025 ... plato.stanford.edu Jun 18, 2004 1 fact
claimIn the Penrose-Hameroff model, the environment inside microtubules is suitable for objective collapses, and the resulting self-collapses produce a coherent flow that regulates neuronal activity and enables non-algorithmic mental processes.
Quantum Approaches to Consciousness plato.stanford.edu Nov 30, 2004 1 fact
claimHenry Stapp posits that a pattern of neural activity may encode an intention and represent a template for action, which serves as the basis for free will.
