Psilocybin acutely alters several cognitive domains, with a localized rather than global focus, in a dose- and time-dependent manner. However, the significant methodological constraints call for further research, in the context of depression and with standardized protocols, with longitudinal studies also imperative.

Efficient learning is critical to adapting to different environments. There are well-known learning principles in cognitive rehabilitation, including errorless (EL) and trial-and-error (T&E) learning; however, little is known about their underlying neural mechanisms. In the current study, to understand the age-related changes in learning benefits and neural mechanisms applying EL and T&E...

ABSTRACT Introduction: Adolescent cannabis use (CU) is associated with impaired attention, executive function, and verbal learning/memory. These associations are generally observed in cross-sectional studies. Longitudinal studies of cannabis users are lacking. Method: The present study examines associations between CU and cognition over time in chronic daily adolescent-onset CUs, as compared to...

This study and our previous report (Hanson, Luciana, & Sullwold, 2008) suggest that moderate MDMA use does not lead to persistent impairments above and beyond that associated with generally heavy drug use, but polydrug use may lead to dose-related temporal and frontoparietal dysfunction. Marijuana use may be particularly problematic. Cause-effect relations are unclear.

The popular recreational drug MDMA or "ecstasy" is a selective serotonin neurotoxin in many species and has been found to be associated with memory dysfunction in human beings. Recent studies suggest that this impairment persists after cessation of use for periods up to at least one year. However, there is no clear indication as yet concerning which stage of memory processing is impaired as a...

Why should conscious recollection be associated with recovery of some memories and not others? A hypothesis is proposed and defended that the medial temporal lobe/hippocampal complex (MTL/H) and related limbic structures comprise a memory module that receives as its input only information that is consciously apprehended. The module then binds or conjoins into memory traces those neural elements...

The relevance of sleep/waking rhythms to issues of human consciousness is reviewed from data in the literature and from personal studies. Consciousness is often considered to be markedly attenuated or absent in sleep. There is, however, much evidence for a rich subjective experience during sleep, much of which is not recalled later. This implies that William James' "stream of consciousness'...
