A spatially constrained low-rank matrix factorization for the functional parcellation of the brain

, 2014
We propose a new matrix recovery framework to partition brain activity using time series of resting-state functional Magnetic Resonance Imaging (fMRI). Spatial clusters are obtained with a new low-rank factorization algorithm that offers the ability to ...

How to Match Cognitive Model Predictions With EEG Data

Topics in Cognitive Science, EarlyView.
Abstract Reliably identifying relevant brain areas implicated by the simulated activity from cognitive models is still an unsolved problem for cognitive modeling, particularly when matching model output with human electroencephalography (EEG) data. We propose a new method involving postprocessing of ACT‐R module activity and clustered EEG component ...

Words and Scents: How Language Shapes and Skews Olfactory Processing

Topics in Cognitive Science, EarlyView.
Abstract Research on language and olfaction presents a paradox. Language appears to support the formation of odor categories, yet it can also hinder odor recognition through verbal interference, highlighting that different olfactory processes get affected in distinct ways.

Modulation of cerebral blood flow and cognition by hyperthermia and hypoxia: An electroencephalographic event‐related potentials perspective

Experimental Physiology, EarlyView.
Abstract Cerebral blood flow (CBF) is essential for sustaining neuronal metabolism and cognitive performance; however, the precise relationship between perfusion and cognition remains unclear. Although ageing and disease are associated with progressive declines in CBF and cognitive impairment, the acute effects of altered CBF under environmental ...

Coupling between global brain blood oxygen level‐dependent activity and cerebrospinal fluid dynamics in young endurance athletes

Experimental Physiology, EarlyView.
Abstract Cerebrospinal fluid (CSF) contributes to brain waste clearance through its coupling with cerebral haemodynamics. Aerobic exercise promotes brain health, but its influence on brain waste clearance remains unclear. This study examined the coupling between CSF and cerebral haemodynamics in endurance athletes. Fifteen young male endurance athletes

Psychotropic medication and the fetal brain

The Journal of Physiology, EarlyView.
Abstract figure legend Brain region changes linked to in‐utero psychotropic exposure. Abstract Medications known to cross the blood–brain barrier (psychotropic medications) are commonly prescribed to women during pregnancy, often for the management of mental illness.
