Hippocampal subfield differences in people with and without recreational ketamine use: Insights from multi‐modal neuroimaging

Addiction, EarlyView.
Abstract Background and aims Recreational ketamine use has increased globally and is associated with psychiatric and cognitive concerns. The hippocampus in preclinical models shows damage and working‐memory disruption with repeated dosing. However, whether specific hippocampal subregions may differ in people with chronic ketamine use remains unclear ...

Effects of Noninvasive Cervical Vagal Nerve Stimulation on Cognitive Performance But Not Brain Activation in Healthy Adults

Neuromodulation: Technology at the Neural Interface, EarlyView., 2020
Abstract Objectives While preliminary evidence suggests that noninvasive vagal nerve stimulation (nVNS) may enhance cognition, to our knowledge, no study has directly assessed the effects of nVNS on brain function and cognitive performance in healthy individuals.

Safety pharmacology of acute mescaline administration in healthy participants

British Journal of Clinical Pharmacology, EarlyView.
Aims Psychedelics, including mescaline, may serve as novel treatments for depression and anxiety. However, data is scarce on the safety of mescaline. Methods The present pooled analysis included two double‐blind, randomized, placebo‐controlled studies with a total of 48 participants and 96 mescaline administrations. Single oral‐dose administrations (n =

Mathematics anxiety: Effects of age, gender and culture

British Journal of Educational Psychology, EarlyView.
Abstract Background Many studies have indicated that mathematics anxiety is a significant problem for many people and is an important topic for research. Mathematics anxiety is multidimensional. In particular, it is important to distinguish between worry and emotionality components, and between trait and state anxiety.

Dose‐dependent impairment of brain functional and microstructural connectivity during leukaemia chemotherapy

British Journal of Haematology, EarlyView.
Prospective functional MRI brain and neurocognitive assessments were performed serially during intensive chemotherapy for a cohort of adults with newly diagnosed acute myeloid leukaemia to elucidate ‘chemobrain’ language phenomena. At completion of consolidation, significant reductions in functional and microstructural connectivity were observed ...

Psilocybin as a novel treatment for chronic pain

British Journal of Pharmacology, EarlyView.
Abstract Psychedelic drugs are under active consideration for clinical use and have generated significant interest for their potential as anti‐nociceptive treatments for chronic pain, and for addressing conditions like depression, frequently co‐morbid with pain.
