Research on brain activity during mystical, meditative, and altered states suggests that both alpha and theta waves are often associated with mystical experiences, but it would be an oversimplification to say that alpha with theta waves are always dominant.
Alpha waves (about 8–12 Hz) are commonly linked to relaxed wakefulness, inward attention, and reduced processing of external stimuli.
Theta waves (about 4–8 Hz) are associated with deep meditation, vivid imagery, memory processes, drowsiness, and some altered states of consciousness.
Studies of experienced meditators, contemplative practitioners, and people reporting mystical-type experiences have frequently found:
Increased alpha power, especially during relaxed absorption.
Increased theta activity, particularly in frontal and midline brain regions.
Sometimes changes in gamma activity (above ~30 Hz), which has also been linked to intense states of awareness and unity experiences.
However, the findings vary depending on:
The type of mystical experience (meditation, prayer, spontaneous experience, psychedelic-induced experience, etc.).
The measurement method (EEG, MEG, fMRI).
The individual's experience level and brain physiology.
A common description is that mystical states often involve a blend of enhanced alpha-theta activity, reflecting a state that is deeply relaxed yet highly internally focused. Some researchers view this as a brain state that is neither ordinary wakefulness nor sleep, but something in between.
If you're asking specifically about mystical experiences induced by meditation versus psychedelics, the neural signatures differ considerably, and psychedelics often show patterns that cannot be described simply as "alpha-theta dominance."
what brainwaves are dominant during experiences of jhana?
The relationship between jhāna (deep meditative absorption in Buddhist traditions) and brainwaves is still an active area of research. There is no established EEG signature that all researchers agree corresponds to jhāna, partly because jhāna is a subjective contemplative state and different traditions define it somewhat differently.
Some findings from studies of highly experienced meditators suggest:
Alpha (8–12 Hz) often increases during states of stable, relaxed concentration and reduced attention to external stimuli.
Theta (4–8 Hz), especially frontal midline theta, is frequently associated with sustained attention, absorption, and deep meditation.
Gamma (>30 Hz) has been observed in some advanced meditators, particularly during states described as intense clarity, non-dual awareness, or highly developed concentration.
In a few studies of practitioners claiming deep absorption states, researchers have reported unusual combinations of strong slow-wave activity and high-frequency activity that do not resemble ordinary wakefulness, sleep, or simple relaxation.
A rough summary is:
Early concentration states approaching jhāna are often associated with increased alpha and theta.
Deeper absorptive states may show more complex patterns, sometimes including gamma synchronization.
There is no consensus that "jhāna = theta" or "jhāna = alpha." The brain activity appears to involve multiple frequency bands and may change across different stages of absorption.
One influential line of research by Richard Davidson and colleagues found elevated gamma synchrony in some highly experienced meditators, while research by Paul Dennison and others studying jhāna practitioners has reported strong alpha-theta patterns and distinctive EEG signatures during reported absorption states. These findings are intriguing but are based on relatively small samples and have not yet produced a universally accepted neural marker of jhāna.
From a traditional Buddhist perspective, it's also worth noting that jhāna is usually defined by phenomenological qualities—such as one-pointedness, rapture, pleasure, equanimity, and stability of attention—rather than by any particular brainwave pattern. The neuroscience is attempting to correlate those experiences with brain activity, but it has not yet reached definitive conclusions.
can neurofeedback permanenetly increase certain brainwave patterns?
Yes, neurofeedback can produce lasting changes in brain activity, but "permanently increasing a specific brainwave" is a stronger claim than the current evidence supports.
Neurofeedback works through operant conditioning: you receive real-time feedback about your brain activity and learn, through practice, to shift it in a desired direction. Over time, some of these learned patterns can persist beyond the training sessions.
Research suggests that neurofeedback can:
Increase the ability to generate certain brain states on demand.
Produce measurable changes in EEG patterns that may last weeks, months, or sometimes longer after training.
Lead to sustained improvements in some symptoms (for example, attention difficulties, anxiety, or insomnia) in certain individuals.
However, several caveats are important:
The brain is dynamic
Healthy brains naturally shift among different frequencies depending on the task.
Permanently locking the brain into high alpha, high theta, or any other single pattern would generally not be desirable.
State versus trait changes
Neurofeedback may create a trait-level tendency toward a pattern (e.g., more alpha during rest), but that is different from maintaining elevated alpha all the time.
The strongest evidence is often for improved self-regulation rather than a fixed alteration of baseline brainwaves.
Evidence quality varies
Some protocols have reasonably good support.
Other claims—such as permanently inducing mystical states, enlightenment, genius-level creativity, or specific spiritual attainments through EEG training—have little scientific support.
Training effects can fade
Like physical fitness, learned neural skills may weaken without practice.
Some people maintain gains for years; others benefit from occasional refresher sessions.
Regarding meditation-related goals, there is interest in training:
Alpha for relaxation and sensory disengagement.
Frontal midline theta for sustained attention and absorption.
Alpha-theta protocols for deeply relaxed, internally focused states.
These protocols may make it easier to enter states associated with meditation or contemplation, but there is currently no evidence that neurofeedback can reliably and permanently create jhāna or mystical experiences independent of continued practice.
A useful analogy is learning a musical instrument: neurofeedback can help the brain learn a skill. Once learned, the skill may persist, but it usually remains something you can access rather than a brain state that stays permanently switched on.
