Found by searching the library for Altered states of consciousness, non-ordinary states, altered consciousness, ASC, then ranked by relevance.
Research on altered states of consciousness (ASCs) in March 2026 indicates that rhythmic drumming at theta frequency can selectively induce ASCs, with stronger theta-band neural tracking linked to greater altered experience, suggesting a bidirectional relationship between theta activity and ASC. A review highlights the autonomic nervous system's potentially critical role in shaping non-ordinary states, proposing that the coexistence of sympathetic and parasympathetic tone is a hallmark of peak states. A theoretical paper argues that deliberately maintaining cognitive performance during ASCs (ASC Competence) could enhance adaptive capacity through neuroplastic mechanisms. However, evidence is limited by small sample sizes, theoretical rather than empirical designs, and a lack of long-term outcome data.
Evidence by study
Direction is which way each study's own result points, not our rating of the study.
What the directions mean
- Supports:
- the study found the intervention worked, or its hypothesis held.
- Opposes:
- it found the opposite, no benefit or a harm.
- No effect:
- no significant difference either way.
- Mixed:
- effects in both directions within the same study.
- Unclear:
- the abstract does not report a direction.

|---|---|---|---|---|
| Neural tracking at theta predicts drumming-induced altered states of consciousness 2026 | within-subjects experimental design | 40 | Supports | Theta-frequency drumming (4 beats per second) selectively induced altered states of consciousness compared to delta and alpha rhythms, and stronger theta-band neural tracking was linked to greater altered experience. |
| URB #424 — The ASC Competence Hypothesis: Altered State Navigation as the Brain's Ultimate Training Modality 2026 | theoretical or philosophical paper | Unclear | Argues that the deliberate practice of maintaining cognitive performance during altered states (ASC Competence) can enhance adaptive capacity through neuroplastic mechanisms, positioning it as a training modality for executive control. | |
| Consciousness Beyond the Brain: The Role of the Autonomic Nervous System in Non-ordinary States of Consciousness 2026 | review | Supports | Reviews evidence that the autonomic nervous system plays a critical role in shaping non-ordinary states of consciousness, proposing that the coexistence of sympathetic and parasympathetic tone is a hallmark of peak NOSCs. | |
| New psychoactive substances and altered consciousness: An emerging challenge for public health 2026 | theoretical/review | Unclear | The abstract is empty, so no findings can be extracted; the title suggests a focus on new psychoactive substances and altered consciousness as a public health challenge. |

theoretical or philosophical paper
Reviews evidence that the autonomic nervous system plays a critical role in shaping non-ordinary states of consciousness, proposing that the coexistence of sympathetic and parasympathetic tone is a hallmark of peak NOSCs.
review
The abstract is empty, so no findings can be extracted; the title suggests a focus on new psychoactive substances and altered consciousness as a public health challenge.
theoretical/review
Points of agreement
- Theta-frequency drumming can selectively induce altered states of consciousness, with neural tracking at theta linked to stronger altered experience.
- The autonomic nervous system, particularly the coexistence of sympathetic and parasympathetic tone, may be a key feature of non-ordinary states.
- Altered states of consciousness may have therapeutic and adaptive potential, as suggested by the review and theoretical paper.
Conflicts
- No direct contradictions are reported; however, the theoretical paper's claim that ASC Competence is a training modality is not empirically tested, contrasting with the experimental evidence from the drumming study.
Gaps
- Durability of effects: no long-term follow-up data on altered states induction or therapeutic outcomes.
- Blinding and control conditions: the drumming study did not mention blinding or a no-stimulation control.
- Population diversity: samples are limited to healthy human participants; clinical populations are not studied.
- Dose-response relationships: the optimal parameters for rhythmic stimulation or ASC Competence training are not established.
- Mechanistic clarity: the role of the autonomic nervous system is proposed but not directly measured in the reviewed studies.
- Theoretical papers lack empirical validation; the ASC Competence hypothesis requires experimental testing.
