Monks' serotonin levels
Transcript of Monks' serotonin levels
Biological level of analysis: neurotransmitters are said to affect human behavior. The neurotransmitter serotonin is believed to affect a person's emotion, sleep and levels of arousal.
Monks' Serotonin Levels:
study by Kasamatsu & Hirai 1999
John Crane's book page 40
To determine how sensory deprivation
affects the brain
Participants went on a pilgrimage for 72 hours without consuming any food or water.
Research was conducted on a holy mountain in Japan.
They did not speak and were exposed to the cold weather in the late autumn.
A group of Buddhist monks
Researchers took blood samples from the participants before and after the pilgrimage.
The participants experienced hallucinations after 48 hours while on top of the mountain.
Researchers found that the serotonin levels had increased in the monks' brains.
The release of serotonin levels were triggered by sensory deprivation. This actually changed the way the monks viewed the world.
The hypothalamus and the frontal cortex located in the brain are activated by high levels of serotonin. This resulted the participants to experience hallucinations.
