Subchronic memantine induced concurrent functional disconnectivity and altered ultra-structural tissue integrity in the rodent brain: revealed by multimodal MRI [PDF]
Background An effective NMDA antagonist imaging model may find key utility in advancing schizophrenia drug discovery research. We investigated effects of subchronic treatment with the NMDA antagonist memantine by using behavioural observation and ...

Abstract Objective Olfactory function is influenced by nasal airflow dynamics and anatomical variations within the nasal cavity. This narrative review evaluates how nasal anatomy and airflow relate to olfactory outcomes, with a particular focus on olfactory changes following functional nasal surgery. Data Sources PubMed.

Magnetic Resonance Imaging of Neuronal Function in the Spinal Cord: Spinal fMRI [PDF]
A review of the current literature on magnetic resonance imaging of neuronal function in the spinal cord (spinal fMRI) is presented. The unique challenges of spinal fMRI are identified as being the small cross-sectional dimensions of the spinal cord, magnetic field inhomogeneity caused by the bone and cartilage in the spine, and motion of cerebrospinal

Abstract Background and Aims Cannabis use disorder (CUD) affects ~50 million people globally. Neuroscientific theories suggest that a blunted neural response to non‐drug rewards is a hallmark of substance use disorders; however, this remains untested in CUD. The current study tested whether brain reward system responses to the anticipation and feedback

Abstract Purpose Physiological pulsations driven by cardiac, respiratory, and vasomotor activity are essential for solute transport within perivascular and perineural cerebrospinal fluid (CSF) pathways that support brain and eye clearance systems. Previous studies have shown that parasympathetic blockade significantly reduces ocular pulsation power and

Safety pharmacology of acute mescaline administration in healthy participants
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 =

Regional-based static and dynamic alterations in Alzheimer disease: a longitudinal study
Background Alzheimer disease (AD) leads to cognitive decline and alters functional connectivity (FC) in key brain regions. Resting-state functional magnetic resonance imaging (rs-fMRI) assesses these changes using static-FC for overall ...

Abstract Aims Insulin signalling in the brain is crucial for systemic metabolic regulation and cognitive function. In some individuals, these effects are reduced, a phenomenon referred to as brain insulin resistance (BIR). This condition may contribute to the elevated risk of cognitive decline and dementia in diabetes, yet its prevalence, mechanisms ...

Energetic dysregulations in psychotic disorders: Targets for new therapeutics
The present review synthesizes literature documenting aberrant energy production and use, specifically related to mitochondrial and redox dysregulation, in psychotic disorders. Findings from different levels of investigation—genetic, cellular, and in vivo imaging—converge on aberrant energy metabolism as a hallmark of psychotic disorders.
