Enhanced visual contrast suppression during peak psilocybin effects: Psychophysical results from a pilot randomized controlled trial

Journal of Vision November 5, 2024 Sophia Jungers, Ranji Varghese, Link Swanson et al. 2 citations

In visual perception, an effect known as surround suppression occurs wherein the apparent contrast of a center stimulus is reduced when it is presented within a higher-contrast surrounding stimulus. Many key aspects of visual perception involve surround suppression, yet the neuromodulatory processes involved remain unclear. Psilocybin is a serotonergic psychedelic compound known for its robust...

Transcendental meditation and hypothalamic-pituitary-adrenal axis functioning: a pilot, randomized controlled trial with young adults.

Stress 2020 Bonnie Klimes-Dougan, Li Shen Chong, Ali Samikoglu et al.

Transcendental meditation (TM) is effective in alleviating stress and anxiety and promoting well-being. While the underlying biological mechanisms of TM are not yet fully explored, the hypothalamic-pituitary-adrenal (HPA) axis represents an index providing important clues embodying the stress system cascade. In this pilot study, young adults were randomly assigned to TM training followed by 8...

Intravenous Ketamine for Adolescents with Treatment-Resistant Depression: An Open-Label Study.

Journal of Child and Adolescent Psychopharmacology September 2018 Kathryn R. Cullen, Palistha Amatya, Mark G Roback et al.

Novel interventions for treatment-resistant depression (TRD) in adolescents are urgently needed. Ketamine has been studied in adults with TRD, but little information is available for adolescents. This study investigated efficacy and tolerability of intravenous ketamine in adolescents with TRD, and explored clinical response predictors. Adolescents, 12-18 years of age, with TRD (failure to...
