Recent neuroimaging studies have demonstrated that spontaneous brain activity exhibits rich spatiotemporal structure that can be characterized as the exploration of a repertoire of spatially distributed patterns that recur over time. The repertoire of brain states may reflect the capacity for consciousness, since general anesthetics suppress and psychedelic drugs enhance such dynamics. However,...

Ketamine is a promising treatment option for patients with Major Depressive Disorder (MDD) and has become an important research tool to investigate antidepressant mechanisms of action. However, imaging studies attempting to characterise ketamine's mechanism of action using blood oxygen level-dependent signal (BOLD) imaging have yielded inconsistent results- at least partly due to intrinsic...

Low-income and African American adults experience severe tobacco-related health disparities. Mindfulness-based interventions show promise for promoting smoking cessation, but most mindfulness research has focused on higher income, Caucasian samples. "iQuit Mindfully" is a personalized, interactive text messaging program that teaches mindfulness for smoking cessation. This qualitative study...

The ventral tegmental area (VTA) mediates incentive salience and reward prediction error through dopamine (DA) neurons that are regulated by local VTA GABA neurons. In young mice, VTA GABA cells exhibit a form of synaptic plasticity known as long-term depression (LTD) that is dependent on cannabinoid 1 (CB1) receptors preceded by metabotropic glutamate receptor 5 (mGluR5) signaling to induce...

INTRODUÇÃO: Os psicodélicos são substâncias que afetam diversos processos cognitivos, causando alterações comportamentais e perceptivas. A psilocibina e seu metabólito ativo, a psilocina, foram identificados como os compostos psicoativos nos Laboratórios Sandoz em 1958 por Albert Hofmann. A psilocibina tem uma estrutura semelhante à serotonina, portanto acredita-se que ela tenha uma ação...

Volitional yoga breathing techniques influence several physiological functions depending on the changes made in depth of breathing, relative duration of exhalation to inhalation, and breath frequency. The practice guidelines for three routinely practiced and researched yoga breathing practices (bhastrika pranayama [bellows breath], bhramari pranayama [bee breath], and kapalabhati pranayama...

Healing therapies are a set of techniques used with the aim of transfusing healthy “bioenergy” to other people in order to restore physical, mental, and emotional balance. It is necessary that something is donated from the healer, that is, something results from his organic metabolism. Also, based on your physical, mental, and emotional health, the energy resulting from your metabolism is...

Despite increased prevalence of maternal cannabis use, little is understood regarding potential long-term effects of prenatal cannabis exposure (PCE) on neurodevelopmental outcomes. While neurodevelopmental cannabis exposure increases the risk of developing affective/mood disorders in adulthood, the precise neuropathophysiological mechanisms in male and female offspring are largely unknown....

There is evidence that cannabis use during adolescence leads to memory and cognitive problems in young adulthood but little is known about effects of early life cannabis exposure on synaptic operations that are critical for encoding and organizing information. We report here that a 14-day course of daily Δ9-tetrahydrocannabinol treatments administered to adolescent rats and mice (aTHC) leads to...
