Primary Outcome Measures:

Brain activity during functional magnetic resonance imaging (fMRI) [ Time Frame: 1 hour ] [ Designated as safety issue: No ]

Estimated Enrollment:	60
Study Start Date:	May 2005
Estimated Study Completion Date:	May 2013
Estimated Primary Completion Date:	May 2013 (Final data collection date for primary outcome measure)

Intervention Details:

Acupuncture needle will be inserted and stimulated by manual twisting by an acupuncturist.

Acupuncture needle will be inserted and electrodes attached to this needle. Electrical current will be passed to stimulate the body via the needle. Current strength will be below pain thresholds.

A sham stimulation will be produced over the body location. no insertion will be made.

Detailed Description:

Acupuncture is an ancient Chinese practice involving the insertion of needles into specific parts of the body for therapeutic purposes. Although the practice has become more popular in the West, the underlying mechanisms of acupuncture have not been thoroughly examined. This study will determine how acupuncture affects human brain activity, particularly during deqi, a unique sensation experienced during acupuncture that is considered essential to the clinical effectiveness of the practice.

This study will comprise 2 clinic visits. At Visit 1, participants will be randomly assigned to receive manual acupuncture; electro-acupuncture, which passes an electrical current through the needles; or some type of sensory stimulation. At Visit 2, participants will again be randomly assigned to receive one of the three interventions. As participants receive their assigned intervention, they will undergo functional magnetic resonance imaging (fMRI) brain scans. Participants will also have their heart rate monitored during the brain scans.
