Shamanic ritual drumming has been used since the Paleolithic era. Recent studies looking into the neuroscience and brain activity related to shamanic journeying have found that journeying enhances attention, learning, self-awareness, confidence and sense of wholeness.  Other benefits of this ritual are found to provide psychotherapeutic effects from the altered states of consciousness (the journey) which relieve stress, increase levels of serotonin and endogenous opioid uptake which activate the paleomammillion brain.  In simpler terms, shamanic drum journeying is GOOD for you!
