Abstract

Excessive expectancy or an aversion to acupuncture makes it difficult to evaluate the efficacy of acupuncture during clinical trials. We investigated whether experimental manipulations of the perception of acupuncture could elicit different responses to identical acupuncture stimulation. Seventeen participants were assessed with the acupuncture belief scale (ABS) and by measuring tactile and pain sensitivity. Identical acupuncture-related pictures and either positive (positive group; n=9) or negative (negative group, n=8) statements related to treatment were presented, and participants used the self-assessment manikin (SAM) to rate each acupuncture-related image. Participants were stimulated with the same intensity for 5 min and then evaluated for acupuncture-induced, self-reported pain. Heart rate variability (HRV) was measured before and after the acupuncture stimulation. Participants in the negative group were less valenced and more aroused in response to the same acupuncture picture compared to those in the positive group. Negative cognition regarding acupuncture modality resulted in a change of the relationship between the pre-experimental expectancy of acupuncture and self-reported pain. The negative group produced an inc...Continue Reading

Amygdala: Sensory Processes

Amygdalae, nuclei clusters located in the temporal lobe of the brain, play a role in memory, emotional responses, and decision-making. Here is the latest research on sensory processes in the amygdala.

Amygdala and Midbrain Dopamine

The midbrain dopamine system is widely studied for its involvement in emotional and motivational behavior. Some of these neurons receive information from the amygdala and project throughout the cortex. When the circuit and transmission of dopamine is disrupted symptoms may present. Here is the latest research on the amygdala and midbrain dopamine.
