...that sends an electrical current through the vagus nerve--a major conduit wiring the heart and intestines--which then delivers it to the brain. Another approach, called regional transcranial magnetic stimulation, uses an electric coil shaped like a figure eight to create a magnetic field inside the pre-frontal cortex, which plays a key role in mood regulation...
...were caused by a failure of the brain to integrate tactile sensations and balance. Transient out-of-body experiences can occur in anyone, but a glance around is usually all it takes to ground the brain in reality again. The right angular gyrus, however, sits quite near the vestibular cortex, the seat of balance. Jolting the Swiss patient's gyrus apparently threw the delicate feedback system out of synch--creating a state of neural chaos that was exacerbated when she moved her eyes and body. Whether shamans achieve the same state through meditation is impossible to say. But if they...
PREFRONTAL CORTEX...
WHAT IT DOES: Parts of the prefrontal cortex regulate emotion and are instrumental in processing rewards and motivation...
...HIGH ROAD Only after the fear response is activated does the conscious mind kick into gear. Some sensory information, rather than traveling directly to the amygdala, takes a more circuitous route, stopping first at the thalamus--the processing hub for sensory cues--and then the cortex--the outer layer of brain cells. The cortex analyzes the raw data streaming in through the senses and decides whether they require a fear response. If they do, the cortex signals the amygdala, and the body stays on alert...
