Syngap1 regulates the synaptic drive and membrane excitability of Parvalbumin-positive interneurons in mouse auditory cortex

Author(s): Francavilla R; Chattopadhyaya B; Damo Kamda JL; Jadhav V; Kourrich S; Michaud JL; Di Cristo G;

SYNGAP1 haploinsufficiency-related intellectual disability (SYNGAP1-ID) is characterized by moderate to severe ID, generalized epilepsy, autism spectrum disorder, sensory processing dysfunction, and other behavioral abnormalities. While numerous studies have highlighted a role of Syngap1 in corti ...

Artificial intelligence-assisted identification of condensing osteitis and idiopathic osteosclerosis on panoramic radiographs

Author(s): Yuksel IB; Boudesh A; Ghanbarzadehchaleshtori M; Ozsoy SC; Bahrilli S; Mohammadi R; Altindag A;

Idiopathic osteosclerosis (IOS) and condensing osteitis (CO) represent radiopaque lesions often detected incidentally within the jaws, posing substantial diagnostic challenges due to their overlapping radiographic characteristics. The objective of this study was to assess the diagnostic efficacy ...

Disentangling prediction error and value in a formal test of dopamine s role in reinforcement learning

Author(s): Usypchuk AA; Maes EJP; Lozzi M; Avramidis DK; Schoenbaum G; Esber GR; Gardner MPH; Iordanova MD;

The discovery that midbrain dopamine (DA) transients can be mapped onto reward prediction errors (RPEs), the critical signal that drives learning, is a landmark in neuroscience. Causal support for the RPE hypothesis comes from studies showing that stimulating DA neurons can drive learning under c ...

Variations in perfusion detectable in advance of microstructure in white matter aging

Author(s): Robinson TD; Sun YL; Chang PTH; Gauthier CJ; Chen JJ;

One of the most promising interventional targets for brain health is cerebral perfusion, but its link to white matter (WM) aging remains unclear. Motivated by existing literature demonstrating links between declining cortical perfusion and the development of WM hyperintensities, we posit that regional WM hypoperfusion precedes deteriorating WM integrity. ...

Deformable detection transformers for domain adaptable ultrasound localization microscopy with robustness to point spread function variations

Author(s): Gharamaleki SK; Helfield B; Rivaz H;

Super-resolution imaging has emerged as a rapidly advancing field in diagnostic ultrasound. Ultrasound Localization Microscopy (ULM) achieves sub-wavelength precision in microvasculature imaging by tracking gas microbubbles (MBs) flowing through blood vessels. However, MB localization faces challenges due to dynamic point spread functions (PSFs) caused by ...

Application of machine learning for predicting the incubation period of water droplet erosion in metals

Author(s): AlHammad K; Medraj M; Tembely M;

Water droplet erosion (WDE) is a critical degradation phenomenon that significantly affects component lifespan and performance in power generation, aerospace, and wind energy industries. The incubation period-the initial phase before visible material loss occurs-is particularly crucial for maintenance planning and material selection yet remains challengin ...

Personalizing brain stimulation: continual learning for sleep spindle detection

Author(s): Sobral M; Jourde HR; Marjani Bajestani SE; Coffey EBJ; Beltrame G;

Personalized closed-loop brain stimulation, in which algorithms used to detect neural events adapt to a user's unique neural characteristics, may be crucial to enable optimized and consistent stimulation quality for both fundamental research and clinical applications. Precise stimulation of sleep spindles-transient patterns of brain activity that occu ...

Characterizing spatiotemporal white matter hyperintensity pathophysiology in vivo to disentangle vascular and neurodegenerative contributions

Author(s): Parent O; Alasmar Z; Osborne S; Bussy A; Costantino M; Fouquet JP; Quesada D; Pastor-Bernier A; Fajardo-Valdez A; Pichet-Binette A; McQuarrie A; Maranzano J; Devenyi GA; Steele CJ; Villeneuve S; ; Dadar M; Chakravarty MM;

White matter hyperintensities (WMHs) are neuroimaging markers widely interpreted as caused by cerebral small vessel disease, yet emerging evidence suggests that a subset may have a neurodegenerative etiology. Current imaging methods have lacked the specificity to disentangle biological processes ...

Hemodynamic correlates of fluctuations in neuronal excitability: A simultaneous Paired Associative Stimulation (PAS) and functional near infra-red spectroscopy (fNIRS) study

Author(s): Cai Z; Pellegrino G; Spilkin A; Delaire E; Uji M; Abdallah C; Lina JM; Fecteau S; Grova C;

Background: The relationship between task-related hemodynamic activity and brain excitability is poorly understood in humans as it is technically challenging to combine simultaneously non-invasive brain stimulation and neuroimaging modalities. Cortical excitability corresponds to the readiness to ...

Leading the way to a safer workplace: What enables supervisors to be servant leaders and enhance subordinates workplace safety behaviors?

Author(s): Chen YP; Hsu YS; Panaccio A; Wang H;

Introduction: Drawing on the Motivation-Ability-Opportunity (MAO) framework and social information processing (SIP) theory, we hypothesized that supervisors demonstrate the highest level of servant leadership when their prosocial motivation (motivation), perspective taking (ability), and perceived collaborative-based HR configuration (opportunity) are all ...

Sex Differences in the Association Between Subjective Social Status and Imaging Markers of Cardiac Inflammation and Fibrosis

Author(s): Sánchez-Carro Y; Moukarzel M; Friedrich MG; Gouin JP; Luu JM;

Objective: Beyond objective socioeconomic status (SES) indicators, subjective social status (SSS), an individual's subjective perception of their social standing relative to others, has been independently linked to cardiovascular disease (CVD) morbidity and mortality. Some studies also report sex differences in the association between SSS and CVD. Thi ...
