The Psychology and Neuroscience of
Mystical Experience

Outline
  • What is our definition of a mystical experience ?
  • Relationship to psychopathology
  • Meditation Studies
  • Michael Persingers work on the role of the
    temporal lobes in mystical experience.
  • Is it all in the brain ?

3
A Universal Experience
  • Two very different examples
  • St Theresa of Avila.
  • Saw angels, cherubim, bright lights and had many
    ecstatic experiences.
  • On St. Peter's Day of 1559 became firmly
    convinced that Christ was present to her in
    bodily form, though invisible. This vision lasted
    almost uninterruptedly for more than 2 years.

4
A Universal Experience
  • Philip K Dick, author of science fiction classics
    like Do Androids Dream of Electric Sheep ? and
    The Man in the High Castle
  • Had a series of visions he called collectively
    2-3-74
  • On the surface the universe consists of a
    spurious projected reality, under which lies an
    authentic substratum of the divine

5
A Universal Experience
  • An individuals mystical experience may be valued
    very differently by society.
  • It may be seen as a deep insight into the divine
    that motivates many followers (Jesus, Buddha,
    Mohammed).
  • Or as an object of ridicule (David Icke).
  • However, to each individual it is likely that the
    experience is profound and meaningful.

6
An attempt at definition
  • William James (1902) cites four features of a
    mystical experience
  • Ineffability - in that it defies expression.
  • Noetic quality - mystical states also seem to be
    states of knowledge.
  • Transiency - mystical states are not sustained
    for long periods (lasting hours rather than days
    or longer).
  • Passivity - when the characteristic sort of
    consciousness has set in, the mystic feels as if
    his own state of will were in abeyance

7
An attempt at definition
  • James definition is perhaps a little narrow,
    assuming a road to Damascus kind of experience.
  • Gellhorn and Keily (1972) make a distinction
    between two types of mystical experience
  • Trophotropic - a meditative state, linked to the
    suspension of autonomous will or intentionality
    (e.g. Zen Buddhist / Hindu Yogi).
  • Ergotrophic - a more frenzied mystical state
    linked to arousal (trance-possession / Sufi
    whirling) and catharsis.

8
An attempt at definition
  • Although Scott Atran (2002) defines one of the
    most outstanding aspects of mystical experience
  • namely, a vivid but diffusely conceived
    awareness of a boundless universe centered on a
    self that has no physical markers or constraints
  • How ever many definitions we take, it seems that
    mystical experience is a widespread phenomena.

9
Link with Psychopathology
  • The link between mystical experience and
    psychopathology is a contentious one.
  • Mental illness, particularly psychosis, can
    induce varying intensities of mystical
    experiences and beliefs (e.g. The Messiah
    Complex)
  • This is contentious because the traditional
    concept of mental illness is one laden with
    negative values, experiences supposedly devoid of
    true meaning.

10
Link with Psychopathology
  • Two views
  • James argued against what he called medical
    materialism saying
  • whatever be our organisms peculiarities, our
    mental states have their substantive value as
    revelations of the living truth.
  • R.D. Laing is often quoted as saying
  • the mystic swims in the same water in which the
    schizophrenic drowns

11
Link with Psychopathology
  • However, there is now increasing evidence that
    the qualitative distinction between psychosis and
    normality is insufficient.
  • Johns and van Os (2001) argue for a continuum
    between frank psychosis and more mundane
    experiences of reality.
  • Verdoux and van Os (2002) showed that unusual
    experiences (unusual perceptions, anomalous
    beliefs) are prevalent throughout the population.
  • However, there must be more to the distinction
    than one purely of degree.

12
Cardiff Pagan Pilot Study
  • Pagans endorse almost twice the amount of
    anomalous experience, but show less distress for
    each experience of belief.

13
Cardiff Pagan Pilot Study
  • This suggests we cannot simply understand all
    mystical experiences as sub clinical psychosis.
  • There must be other factors which make certain
    types of mystical beliefs and experiences
    beneficial.
  • Watch this space !

14
Brain Imaging of Meditation
  • Meditation is particularly suited to being
    studied by cognitive neuroscience.
  • Changes of consciousness can be induced and
    participants stay immobile.
  • This makes ideal conditions for neuroimaging
    (brain scanning) of such states.

15
Newberg et al (2001)
  • Used SPECT neuroimaging to scan eight experience
    Tibetan Buddhist meditators.

Increased activation
Decreased activation
16
Side View of Brain
Parietal lobe
Frontal lobe
17
Newberg et al (2001)
  • The prefrontal cortex is known to be involved
    with attention and focus.
  • The parietal cortex with object associations and
    spatial knowledge.
  • Newberg et al speculate that meditation causes
  • increased mental focus
  • breakdown of the boundary between self and other
  • can be explained by the changes in activation in
    these brain areas during meditation.

18
Blanke et al (2002)
  • Stimulation of the right angular gyrus caused
    reliable out of body experiences.
  • Further evidence for the role of the parietal
    cortex in meditating self - other boundaries.

19
Persinger and Mystical Experience
  • Michael Persinger has linked mystical experience
    with the several connected brain areas.

Amygdala
Hippocampus
Temporal lobes
20
Links with TLTs
  • He has found that levels of seizure like
    activation called temporal lobe transients in the
    temporal lobes are related to
  • A whole range of anomalous beliefs and
    experiences (sensed presences, time dilation, out
    of body experiences, auditory perceptions).
  • Levels of paranormal beliefs.
  • Levels of religiosity.

21
Temporal Lobe Readings
  • EEG reading from temporal lobes during
    Transcendental Meditation session.

especially meaningful and that she felt being

22
Temporal Lobe Readings
  • EEG reading from temporal lobes during
    glossolalia (speaking in tongues).

with the Spirit occurred during the latter
periods of the session
23
Temporal Lobe Stimulation
  • Persinger has installed a system in the side of a
    motor bike helmet to produce weak complex
    magnetic fields over the temporal lobes.
  • Right temporal, or bilateral stimulation produced
    sensations of fear and sensed presences.

24
Persingers Conclusions
  • Rather dramatically, Persinger concludes
  • This experimental procedure could be employed to
    explore the idea that the experience of a sensed
    presence is a resident property of the human
    brain and may be the fundamental source for
    phenomena attributed to visitation by gods,
    spirits and other ephemeral phenomena

25
Is it all in the brain ?
  • Skeptics use such studies to argue that mystical
    experience is internally generated entirely by
    neural systems and has no intrinsic value.
  • However, this is reading too much into the data
    at the present time.
  • Whilst the evidence suggests that some
    experiences may be purely internally generated it
    cannot say that all are.
  • No such distinction can be made.
  • In fact, science has a lot of problems even
    addressing this problem, as it only adequately
    addresses falsifiable hypothesis.

26
Is it all in the brain ?
  • We must also question whether such judgements are
    of any use at all.
  • Mystical experiences have greatly benefited
    individuals and society as a whole.
  • Why use our understanding of how the brain is
    involved in these experiences to make value
    judgments of their validity ?
