The Uluzzian and Châtelperronian: No Technological Affinity in a Shared Chronological Framework.

Unlabelled: The Châtelperronian and Uluzzian techno-complexes are identified in western Europe in the same stratigraphic position, between the late Middle Palaeolithic and other Upper Palaeolithic assemblages. Both industries include retouched artefacts with abrupt retouch and arched backs, and radiometric dating indicates that these two technocomplexes belong to the same window of time. Here, we provide a detailed, qualitative technological comparison of two Châtelperronian and two Uluzzian lithic assemblages based on a collaborative, first-hand examination of these collections.

Investigating the cognitive architecture of verbal fluency: evidence from an interference design on 487 controls.

Introduction: Numerous studies have explored the linguistic and executive processes underlying verbal fluency using association designs, which provide limited evidence. To assess the validity of our model, we aimed to refine the cognitive architecture of verbal fluency using an interference design.

Methods: A total of 487 healthy participants performed letter and semantic fluency tests under the single condition and dual conditions while concurrently performing a secondary task that interferes with speed, semantics, phonology, or flexibility.

Cognitive impacts of unilateral MR-guided focused ultrasound thalamotomy: a meta-analysis and a call for systematic neuropsychological assessment.

Objective: Pharmacoresistant tremors, often seen in Parkinson disease and essential tremor, significantly impair patient quality of life. Although deep brain stimulation has been effective, its invasive nature limits its applicability. MR-guided focused ultrasound (MRgFUS) thalamotomy offers a noninvasive alternative, but its cognitive impacts are not fully understood.

Do Amyloid Cerebral Deposits Influence the Long-Term Poststroke Cognitive Outcome?: The IDEA3 Study.

Background: Although the presence of amyloid deposits is associated with a more severe cognitive status in patients with stroke at baseline, its influence on the subsequent cognitive outcome has not been extensively assessed. The primary objective of the present study of the IDEA3 (Imagerie des dépôts amyloïdes cérébraux par florbetapir AV-45 et diagnostic des déficits cognitifs et démence post Accident Vasculaire Cérébral) cohort was to determine the influence of amyloid positron emission tomography (PET) status on the 5-year cognitive outcome.

Methods: This longitudinal study performed in Amiens University Hospital (inclusions: October 2014 to October 2019; last visits: October 2018 to February 2023) has included 91 patients with stroke (ischemic stroke, 89%; hemorrhagic stroke, 11%) with florbetapir PET data at baseline (positive, n=14).
