“…At the psycho‐physiological level, brain functional imaging has located the neuro‐chemical circuitry activated when participants expect they will receive, or believe they are receiving, a pain relieving intervention [116, 118]. In fact, the changes in brain activity are similar to those occurring when genuine interventions are delivered [118, 119, 129]. As such, there is mounting evidence in support of a physiological basis for subjective constructs ( e.g.…”

“…attitudes and expectations) surrounding an intervention contributes to positive therapeutic outcomes [116][117][118]. This is called the placebo effect and can occur in both clinical trials and clinical practice [119,120]. In clinical trials, researchers may attempt to isolate the placebo effect from the direct physiological effects of an intervention.…”

“…It should be stressed that a response to an agent usually increases with increasing concentration; in contrast, a placebo effect does not depend on concentrations, while homeopathic remedies can be extremely diluted so that the agent can be absent in the solution. For research purposes, placebo effects can be excluded in animal experiments without conditioning [ 24 , 25 ] and especially in plants [ 19 ], where hormetic effects can be studied.…”

“…Mentionnons tout d'abord le corpus de travaux (pour une revue voir [11]) qui ont examiné les mécanismes neurobiologiques de l'effet placebo c'est-à-dire «l'effet thérapeutique obtenu par l'administration de comprimés, liquides, injections et toutes procédures qui n'ont pas d'effet spécifique sur la maladie à traiter» ( [12], p. 315). On dispose aujourd'hui de résultats sur la compréhension psychobiologique de l'effet placebo qui indiquent que ce dernier peut être attribuable à des mécanismes comme le conditionnement pavlovien et/ou les attentes du patient [11].…”

“…Les psychothérapies partagent avec l'effet placebo le fait d'avoir probablement «une efficacité en partie attribuable au conditionnement du patient (contexte et rituel des séances) ou à son attente conviction vis-à-vis de la thérapeutique ou du thérapeute […]» ( [12], p. 317), tout en ayant par ailleurs démontré une efficacité supérieure au traitements non-spécifiques. Actuellement, il existe de nombreux travaux, à l'instar des résultats sur l'effet placebo, qui indiquent que les thérapies psychologiques produisent des changements au niveau neuronal (pour une revue, voir [13]).…”
