Global Workspace Neural Signatures to Conscious Access Timing
This interactive tool presents the timeline and key neural signatures associated with conscious access as described by the Global Neuronal Workspace Theory (GNWT).
| Time (ms) | Neural Signature | Role in Conscious Access |
|---|---|---|
| ~100 | P1 / N1 | Early, unconscious sensory processing |
| ~200 | N200 / N2 / N2pc | Threshold detection and attentional filtering |
| ~250–350 | P300 / P3b | Ignition: global broadcasting of conscious content |
| 200–500+ | Gamma synchrony / percolation | Sustains integrated conscious state |
Summary & Key Insights
- Conscious access follows a feedforward → threshold crossing → ignition progression within ~200–350 ms.
- N200 / N2pc signals attentional selection; P3b signals global workspace activation.
- Gamma synchrony and critical dynamics enable distributed information integration required for consciousness.
- GNWT emphasizes ignition and sustained recurrent loops during conscious access.
