There is considerable evidence from the literature that psychedelics, such as N,N-dimethyltryptamine (DMT), are safe and effective treatments for depression. However, clinical administration to induce psychedelic effects and expensive psychotherapy-assisted treatments likely limit accessibility to the average patient. There is emerging evidence that DMT promotes positive behavioral changes in...
We present the development and characterization of a nasal drug delivery system comprised of a thermosensitive mucoadhesive hydrogel based on a mixture of the polymers Poloxamer 407, Poloxamer 188 and Hydroxypropyl-methylcellulose, and the psychedelic drug 5-methoxy-N,-N-dimethyltryptamine. The development relied on a 3 × 3 Box-Behnken experimental design, focusing on optimizing gelification...

Depression is a critical mental ailment as it impacts about 5% of the global population, prompting scientists to create more efficacious antidepressants. The monoamine-deficiency hypothesis suggests that depression is caused by the depletion of certain neurotransmitters like serotonin, norepinephrine, and dopamine in the brain, where serotonin plays the most critical role among all and has been...
5-MeO-DMT is a psychedelic substance with a short duration of action and intensive effects. Its therapeutic efficacy and practicality may significantly surpass those of classical psychedelics such as ayahuasca and LSD. This retrospective ethnographic inquiry features a woman in her mid-thirties who witnessed her mother's violent suicide and its bloody aftermath at the age of three. Before and...
Ayahuasca, un té utilizado inicialmente por pueblos amerindios, con fines medicinales, religiosos y sacramentales, y luego se difundió en muchas partes del mundo en contextos urbanos, que, además de su uso religioso y espiritual, también el uso recreativo. El té de ayahuasca contiene un perfil químico bien característico de compuestos alcaloides psicoactivos que son N, N-dimetiltriptamina (DMT)...
Exploring the intricate relationship between brain's structure and function, and how this affects subjective experience is a fundamental pursuit in neuroscience. Psychedelic substances offer a unique insight into the influences of specific neurotransmitter systems on perception, cognition and consciousness. Specifically, their impact on brain function propagates across the structural...
5-methoxy-N,N-dimethyltryptamine (5-MeO-DMT) is a potent classical psychedelic known to induce changes in locomotion, behaviour, and sleep in rodents. However, there is limited knowledge regarding its acute neurophysiological effects. Local field potentials (LFPs) are commonly used as a proxy for neural activity, but previous studies investigating psychedelics have been hindered by confounding...
Psychedelics, including N, N, Dimethyltryptamine (DMT), are being increasingly explored for therapeutic potential to treat psychiatric disorders such as depression, anxiety, and post-traumatic stress disorder. These and other psychiatric conditions have a bidirectional relationship with sleep patterns but the impact of psychedelics, particularly DMT, on sleep architecture is incompletely...
Aberrant neuronal Sigma-1 receptor (Sig-1r)-mediated endoplasmic reticulum (ER)- mitochondria signaling plays a key role in the neuronal cytopathology of Alzheimer's disease (AD). The natural psychedelic N, N-dimethyltryptamine (DMT) is a Sig-1r agonist that may have the anti-AD potential through protecting neuronal ER-mitochondrial interplay. 3×TG-AD transgenic mice were administered with...
