The Consciousness Atlas is an interactive web app that visualizes more
than 450 theories of consciousness. It is based on Robert Lawrence
Kuhn's 2024 paper,
"A Landscape of Consciousness". The Atlas maps theories that address phenomenal consciousness - the
subjective feel of experience, such as the redness of red.
What the Atlas is
The Atlas is a visual reference built on Kuhn's taxonomy. It presents
the full set of theories at once so you can explore the field visually
and open any theory to read its entry, like an encyclopedia with
structured entries. Each theory entry shows a concise identity line,
conceptual ground, suggested mechanism, empirical notes, implications,
and sources.
Why this exists
Consciousness is studied across disciplines - neuroscience,
philosophy, and sometimes spiritual or anomalous-state research.
Kuhn's paper collects and organizes hundreds of theories along a
spectrum from most physical to least physical. The Atlas puts that
organization into a visual form so readers, students, and researchers
can quickly see how different positions relate and where each theory
sits on the spectrum.
How it works
Theories are grouped into ten main categories, arranged by their
stance on the physical-to-nonphysical spectrum. Examples of categories
include Materialism, Non-Reductive Physicalism, Functionalism,
Quantum-based theories, Panpsychism, Monism, Dualism, Idealism,
Anomalous States, and Challenge Theories. The app shows the whole map
at once. Click any theory to read its structured entry, which includes
references to canonical sources and named thinkers.
Who it is for
- Students learning philosophy of mind and cognitive science
-
Researchers and lecturers looking for an at-a-glance comparative
resource
-
Journalists and writers who need a quick reference to the range of
positions
-
Curious readers who want a clear view of what people mean when they
talk about consciousness
What the Atlas does not do
The Atlas does not endorse or rank theories. It is a visualization and
reference based on Kuhn's taxonomy - collect and present, not judge.
It does not attempt to settle the hard problem of consciousness. It is
a tool for exploration and comparison.
A note from Kuhn
Kuhn explicitly states the project's purpose: "collect and categorize,
not assess and adjudicate." The Consciousness Atlas follows that
approach. The data and structure are derived from Kuhn's paper;
feedback and suggested corrections are welcome, but the app is a
visualization layer on top of Kuhn's work.
Kuhn was not involved in the design or content of the Consciousness
Atlas, other than his original paper, 'A Landscape of Consciousness,'
which is the sole source.
FAQ
What is phenomenal consciousness?
Phenomenal consciousness refers to subjective experience - the
qualitative feel of being aware, like the taste of coffee or the
redness of red.
How many theories does the Atlas include?
The Atlas visualizes over 220 individual theories, grouped into ten
broad categories.
Does the Atlas show which theory is true?
No. The Atlas presents theories neutrally. It is a map, not an
argument for any single position.
Is the Atlas academic?
The Atlas is based on an academic source - Robert Kuhn's 2024 paper,
"A Landscape of Consciousness" - and links to canonical sources
where available.
Summary
The Consciousness Atlas is a straightforward visualization tool: it
presents Kuhn's taxonomy as a single, explorable map and lets users
open individual theory entries to read structured, referenced
summaries. It is designed to make this complex field easier to survey
and to serve as a practical reference.

Singer and Melloni’s Large-Scale Synchrony
Consciousness as Large-Scale Neural Synchrony
Wolf Singer and Lucia Melloni argue that consciousness arises from transient synchronization of neural assemblies across distant brain regions, rather than from activity in any particular area. Long-range gamma-band synchrony, paced by slower theta rhythms, binds separately computed features into one percept and separates conscious from unconscious processing.
Wolf Singer, Lucia Melloni
What consciousness is
Consciousness is a mode of coordination: the temporal alignment of distributed neural processes across distant brain areas. Singer and Melloni call the theory interaction-based rather than content-based or location-based.
Mind and body
Consciousness is an emergent property of metastable brain dynamics. It arises from the dynamical configuration of activity rather than from the anatomical substrate as such.
Mechanism
Binding by synchrony: distributed neurons that oscillate in phase form coherent assemblies, and long-range gamma synchrony across specialized regions marks conscious perception.
Core claims
- Co-activation of feature-specific neurons is not enough for conscious perception; the neurons must also oscillate in synchrony.
- EEG and intracranial studies of masking, binocular rivalry, and attentional blink link conscious perception with brief long-range synchronization.
- Unconscious processing, even when semantically rich, stays local and lacks long-range synchrony.
- Gamma synchrony tracks the updating of conscious content and theta oscillations its maintenance.
Criticisms
Singer and Melloni set their view against Global Workspace Theory, which locates consciousness in fronto-parietal broadcasting, and against local recurrent theories, which locate it in feedback within sensory areas. Showing that synchrony correlates with consciousness does not by itself show that it constitutes it.
Implications
- AI consciousness: Uncertain
- If consciousness lies in the dynamical configuration of interacting units, a system with comparable large-scale synchrony might qualify, but Singer and Melloni frame the account for biological brains.
- Survival beyond death: No
- Since consciousness is a mode of coordination among living neural assemblies, it ends when that activity stops.
- Virtual immortality: Uncertain
- The view ties consciousness to dynamics rather than anatomy, which leaves open, but does not settle, whether a faithful dynamical copy could be conscious.
