The Wim Hof method (WHM) is a behavioral intervention technique that consists of deep breathing exercises, cold exposure and meditation. In light of the crucial role of the cannabinoid system in modulating neurotransmitter release through a negative feedback mechanism that aims at the maintenance of network homeostasis, our study investigated changes in cannabinoid type 1 (CB1) receptor binding...
Predominant concepts assert that conscious willful processes do not assert a significant influence on autonomic functions associated with physiological homeostasis (e.g., thermal regulation). The singular purpose of this review is to promote a reappraisal of concepts regarding the circumscribed role of hierarchical control systems. To effect this reappraisal, we assess the interaction between...
The defense of body temperature against environmental thermal challenges is a core objective of homeostatic regulation governed by the autonomic nervous system. Autonomous mechanisms of thermoregulation are only weakly affected by top-down modulation, allowing only transient tolerance for extreme cold. There is however, anecdotal evidence of a unique set of individuals known for extreme cold...

Structural alterations of the brain in schizophrenia have been associated with genetic and environmental factors. Among the environmental factors, cannabis use has been associated with increased risk for patients with schizophrenia, but the effect of cannabis on their brain structure is unclear. We examined gray matter alterations in first episode schizophrenia patients (FES) with cannabis use...
