Abstract Psychedelic drugs exert rapid and profound effects on human consciousness [1–7] and are increasingly being investigated for their therapeutic potential [8–14]. Yet the transcriptional programs through which they may reshape brain function and structure remain incompletely understood, in part because the available evidence is heterogeneous and largely preclinical [15, 16]. In a...

First-line dictionary definitions of ‘plasticity’ describe it as the ability (of a thing) to be shaped or molded; we call this ‘plasticity proper’. In neuroscience, however, ‘neural plasticity’ or ‘neuroplasticity’ is defined as an induced change in brain function or structure. These two plasticities are not the same. Several (but not all) popular biomarkers of neuroplasticity index part of an...

Focused attention meditation (FA) is a foundational and widely studied practice that cultivates sustained concentration by focusing on a specific object, such as the breath, while disengaging from distractions. Numerous studies have investigated the neurophysiological mechanisms of FA, examining aspects such as spectral power, connectivity patterns, and neural entropy. However, despite this...

Abstract: Dual-process models from neuroscience suggest that addiction is driven by dysregulated interactions between bottom-up neural processes underpinning reward learning and top-down neural functions subserving executive function. Over time, drug use causes atrophy in prefrontally mediated cognitive control networks and hijacks striatal circuits devoted to processing natural rewards in...

This article spotlights problematic assumptions and practices in clinical psychedelic research that together hamper the field’s ability to demonstrate causal identification, contributing to confusion and misunderstanding: (1) the main problematic assumption is that pretreatment expectancy causes therapeutic response; while expectancy predicts response to most treatments, it is becoming...
