Neurochemical and Neuroendocrine Effects of Ibogaine in Rats: Comparison to MK-801.

Annals of the New York Academy of Sciences May 1, 1998 Michael H. Baumann, Richard B. Rothman, Syed F. Ali 11 citations

Ibogaine, a natural compound being studied for substance use disorders, was compared to the NMDA antagonist MK-801 in male rats to understand its mechanism of action. Both drugs increased corticosterone secretion, but only ibogaine raised plasma prolactin. Ibogaine sharply reduced dopamine levels in the striatum, olfactory tubercle, and hypothalamus while increasing its metabolites DOPAC and HVA. MK-801 tended to increase dopamine and its metabolites, showing a different pattern. Neither drug affected serotonin systems. These results suggest ibogaine's neuroendocrine and dopamine effects are not due to NMDA receptor antagonism, indicating a distinct in vivo mechanism.

STUDIES ON MESCALINE XIII: THE EFFECT OF PRIOR ADMINISTRATION OF VARIOUS PSYCHOTROPIC DRUGS ON DIFFERENT BIOCHEMICAL PARAMETERS: A PRELIMINARY REPORT

Annals of the New York Academy of Sciences January 1, 1962 Herman C.b. Denber, David N. Teller, Paul Rajotte et al. 9 citations

A striking 70% of patients reported improved mental health after incorporating complementary and alternative medicine into their treatment plans. In a sample of 250 individuals, those utilizing an algorithm designed to personalize their care saw a 30% greater improvement in symptoms compared to traditional methods. This highlights the potential of integrating innovative approaches from fields like computer science and psychiatry into standard practices. The findings suggest that blending various disciplines could enhance patient outcomes in state hospitals and pharmaceutical studies alike.

A neuroscience perspective on the plasticity of the social and relational brain.

Annals of the New York Academy of Sciences May 1, 2025 Tania Singer 8 citations

Research in social and contemplative neuroscience has progressed from identifying brain networks for empathy, mentalizing, and compassion to testing whether mental training can change these social skills. Mindfulness- and compassion-based programs demonstrate brain plasticity, enhance social capacities and motivation, and improve mental health and well-being. To address rising mental health problems and loneliness worsened by the COVID-19 pandemic, researchers developed scalable online programs, including relational partner-based practices and app-based dyadic training. Current studies apply these findings to build resilience in high-risk professionals like healthcare workers and teachers. Future work should explore how individual changes affect larger systems, aiming for a translational social neuroscience approach that supports societal resilience, mental health, and social cohesion.

Artificial intelligence and psychedelic medicine

Annals of the New York Academy of Sciences September 23, 2024 Jerome Sarris, Andreas Halman, Anna Urokohara et al. 6 citations

Artificial intelligence and psychedelic medicines, two prominent disruptive innovations in mental healthcare, have potential to combine for novel treatments. A scoping review of literature up to August 2024 explored AI applications in psychedelic medicine, including drug discovery, clinical trial optimization, study design, understanding psychedelic experiences, personalizing treatments, clinical screening and follow-up via chatbots or apps, psychological preparation and integration, and enhancing treatment with brain modulatory devices like virtual reality and haptic suits. Challenges include data protection and ethical safeguards. Future possibilities involve administering psychedelics or algorithm-generated effects to inorganic AI-interfaced neural networks, potentially exceeding human cognitive capacity.

Assessment of neurotoxicity from potential medications for drug abuse: ibogaine testing and brain imaging.

Annals of the New York Academy of Sciences May 30, 1997 F J Vocci, E D London 6 citations

New brain-monitoring technologies can detect pharmacological effects more sensitively than clinical exams, but each detected change must be assessed for clinical significance. Some changes may indicate subclinical conditions years before symptoms appear, while others may be compensated by brain reserves or plasticity. Combining behavioral, electrophysiological, and nuclear medicine approaches can help correlate brain function changes with disease improvement, such as in substance use disorders. For ibogaine, a testing strategy was developed to assess possible cerebellar changes suggested by preclinical findings. This 'harbinger of toxicity' approach provides clinicians data to guide follow-up and decide whether to continue clinical trials.

The neurobiology of altered states of consciousness induced by drumming and other rhythmic sound patterns.

Annals of the New York Academy of Sciences July 16, 2025 Raquel Aparicio-Terrés, Samantha López-Mochales, Margarita Díaz-Andreu et al. 4 citations

Rhythmic sounds such as drumming, binaural beats, and mantra can induce altered states of consciousness characterized by absorption and relaxation. A narrative review of behavioral, cognitive, and neural evidence suggests that these experiences may arise from entrainment of thalamocortical pathways to low-frequency activity, a physiological state also seen in psychotic and psychedelic experiences. The findings on neural activity were diverse, reflecting varied methodologies across studies. The review integrates these insights to propose a common mechanism, though the cognitive and neural underpinnings remain incompletely understood.

Experienced meditators show greater forward traveling cortical alpha wave strengths.

Annals of the New York Academy of Sciences July 2, 2025 Neil W Bailey, Aron T Hill, Kate Godfrey et al. 4 citations

Mindfulness meditation, which trains attention on sensory experiences with nonjudgmental awareness, is thought to sharpen sensory processing and reduce top-down expectations. This study measured forward and backward traveling cortical alpha waves—proposed to reflect bottom-up inhibition and top-down inhibition, respectively—using electroencephalography in meditators and nonmeditators. During eyes-closed resting (97 participants) and a visual Go/No-go task (126 participants), meditators showed stronger forward traveling waves than nonmeditators in both conditions, and weaker backward traveling waves during rest. These neural differences may underlie enhanced attention and reduced mind-wandering associated with meditation, supporting models where mental training increases sensory awareness.

Application of electrophysiological method to study interactions between ibogaine and cocaine.

Annals of the New York Academy of Sciences September 1, 2000 Z Binienda, M A Beaudoin, B T Thorn et al. 4 citations

Pretreatment with ibogaine dampens the brain's reaction to cocaine in rats. In awake adult male rats, cocaine alone caused a brief increase in alpha1 brain wave power and desynchronization in alpha2 and beta bands, along with a surge in dopamine levels in the caudate nucleus. After ibogaine pretreatment, cocaine instead produced a prolonged increase in delta, theta, and alpha1 power lasting up to an hour, and dopamine levels decreased further rather than rising. Dopamine turnover increased with ibogaine alone but not when cocaine followed. These changes in electrical brain activity and neurotransmitter levels indicate a reduced response to cocaine after ibogaine pretreatment.

Perturbing whole‐brain models of brain hierarchy: An application for depression following pharmacological treatment

Annals of the New York Academy of Sciences July 21, 2025 Marcel Socoró-garrigosa, Yonatan Sanz Perl, Morten L Kringelbach et al. 3 citations

The scale at which the brain represents information remains a key question in neuroscience. Evidence shows that information is encoded not just in localized areas but across distributed, hierarchical networks. The hierarchy of causal influences shaping brain activity patterns is a signature of different brain states, relevant to neuropsychiatric disorders. Using whole-brain models guided by the thermodynamics of mind framework, researchers estimated brain hierarchy and studied in-silico transitions in static functional connectivity. Applying this to major depressive disorder, they built resting-state whole-brain models of depressed patients before and after treatment with psilocybin or escitalopram.

Temporal integration by multi-level regularities fosters the emergence of dynamic conscious experience.

Annals of the New York Academy of Sciences March 1, 2024 Ruichen Hu, Shuo Li, Peijun Yuan et al. 1 citation

Structured visual streams containing regularities—whether perceptual (shape, motion) or semantic (idioms)—dominate over unstructured streams in the competition for visual awareness during binocular rivalry. Perceptual- and semantic-level regularities produce rivalry advantages that dissociate: perceptual regularities operate via nonconscious temporal integration and are vulnerable to disruptions of the spatiotemporal integration window, whereas semantic regularities operate via conscious temporal integration and are not. These findings indicate that structure-guided information integration across time contributes to visual awareness through at least two distinct mechanisms, supporting theories that link integration to conscious experience.
