Traditional Buddhist meditations reduce mismatch negativity in experienced monk- practitioners

Area of Science:

• Neuroscience
• Cognitive Science
• Buddhist Studies

Background:

• Buddhist traditions offer millennia of subjective consciousness exploration through meditation.
• Integrating neuroscience with Buddhist meditative practices can elucidate consciousness mechanisms.
• This study investigates physiological changes during Buddhist meditative states.

Purpose of the Study:

• To examine the psychophysiological effects of Buddhist meditations on sensory and cognitive processing.
• To understand how altered states of consciousness during meditation impact external stimuli recognition.

Main Methods:

• Studied auditory event-related potentials (ERPs) using a passive oddball paradigm.
• Compared ERPs during Buddhist meditation (concentration, analytical) versus relaxed wakefulness.
• Utilized a cohort of 115 Buddhist monks.

Main Results:

• Meditation significantly decreased mismatch negativity amplitudes.
• Reduced amplitudes were observed for N1, P2 components (deviant stimuli) and P3a component (novel stimuli).
• These findings indicate diminished engagement with external sensory changes during meditation.

Conclusions:

• Buddhist meditations are associated with reduced physiological processing of external stimuli.
• This suggests a withdrawal from sensory input and attentional disengagement from the external world.
• Neuroscience provides objective measures for subjective meditative experiences.
