High-Potency Marijuana Impairs Executive Function and Inhibitory Motor Control
Johannes G. Ramaekers,Gerhold Kauert,Peter van Ruitenbeek,Eef L. Theunissen,Erhard Schneider,Manfred R. Moeller +5 more
TL;DR: The data suggest that high potency marijuana consistently impairs executive function and motor control and use of higher doses of THC in controlled studies may offer a reliable indication of THC induced impairment as compared to lower doses that have traditionally been used in performance studies.
Journal ArticleDOI
Cognitive, psychomotor and actual driving performance in healthy volunteers after immediate and extended release formulations of alprazolam 1 mg
Tim R.M. Leufkens,Annemiek Vermeeren,Beitske E. Smink,Peter van Ruitenbeek,Johannes G. Ramaekers +4 more
TL;DR: The acute impairing effects of alprazolam XR 1 mg on driving and psychomotor functions were generally less, as compared to its immediate-release equivalent, but still of sufficient magnitude to increase the risk of becoming involved in traffic accidents.
Journal ArticleDOI
GABA levels and measures of intracortical and interhemispheric excitability in healthy young and older adults: an MRS-TMS study.
Lize Hermans,Oron Levin,Celine Maes,Peter van Ruitenbeek,Kirstin Heise,Richard A.E. Edden,Nicolaas A.J. Puts,Ronald Peeters,Bradley R. King,Raf Meesen,Inge Leunissen,Stephan P. Swinnen,Koen Cuypers,Koen Cuypers +13 more
TL;DR: It is suggested that healthy aging gives rise to altered inhibition at the postsynaptic receptor level, which does not seem to be associated with MRS-assessed GABA+ levels.
Journal ArticleDOI
Individual differences in brainstem and basal ganglia structure predict postural control and balance loss in young and older adults
Matthieu P. Boisgontier,Boris Cheval,Sima Chalavi,Peter van Ruitenbeek,Peter van Ruitenbeek,Inge Leunissen,Oron Levin,Alice Nieuwboer,Stephan P. Swinnen +8 more
TL;DR: Ass associations between postural performance and corticosubcortical brain regions were examined in young and older adults using multiple structural imaging and linear mixed models and showed that of the regions involved in posture, the brainstem was the strongest predictor of postural control and balance.
Journal ArticleDOI
Subcortical volumetric changes across the adult lifespan: Subregional thalamic atrophy accounts for age-related sensorimotor performance declines
Leen Serbruyns,Inge Leunissen,Toon Huysmans,Koen Cuypers,Koen Cuypers,Raf Meesen,Raf Meesen,Peter van Ruitenbeek,Jan Sijbers,Stephan P. Swinnen +9 more
TL;DR: It is concluded that subregional volume assessment by means of shape analyses offers a sensitive tool with high anatomical resolution in the search for specific age-related associations between brain structure and behavior.
