Abstract Objective Hallucinogen Persistent Perception Disorder (HPPD) is a condition where the effects of hallucinogenic drugs reoccur long after the acute effects have stopped. No established risk factors or mechanisms for HPPD have been identified. However, reports have suggested a risk phenotype for HPPD due to associations with other perceptual disturbances. With recent increases in...
This study builds on brief focused mindfulness meditation (BFMM) to examine its associations with physiological indices and electroencephalographic (EEG) neural features related to stress in young adults. In addition, deep learning models are employed to identify complex, nonlinear patterns in EEG signals during BFMM, aiming to determine the most effective classification model. Twenty-nine...
Abstract: Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment...

Abstract Our study seeks to investigate the neural mechanisms underlying brief mindfulness meditation through the utilization of electroencephalogram (EEG) recordings and machine learning techniques. Twenty-four participants underwent mindfulness training, with pre- and post-practice physiological assessments and EEG recordings. Deep learning was used to analyze EEG data to predict mindfulness...
