Micro magnetic resonance spectroscopy for noninvasive metabolic screening of mammalian embryos and oocytes

Analyzing cellular health and metabolism without compromising cell integrity is a major challenge. We present a noninvasive technique using micro magnetic resonance spectroscopy (micro MRS) for nondestructive metabolic fingerprinting at the single-cell sca ...

A neurometabolic mechanism involving dmPFC/dACC lactate in physical effort-based decision-making

Maria del Carmen Sandi Perez, Lijing Xin, Nicolas Clairis, Arthur Barakat

Motivation levels vary across individuals, yet the underlying mechanisms driving these differences remain elusive. The dorsomedial prefrontal cortex/dorsal anterior cingulate cortex (dmPFC/dACC) and the anterior insula (aIns) play crucial roles in effort-b ...

Neurobiological and metabolic basis of motivation and effort-based decision-making - A human 1H-MRS, fMRI and machine learning study

Arthur Barakat

Motivation is a multifaceted phenomenon that we explore within the framework of decision-making. Through this cognitive process, actions are directed towards specific goals by performing a trade-off between the cost and benefit of an action. The dorsomedia ...

How do visual skills relate to action video game performance?

Michael Herzog, Aline Françoise Cretenoud, Oh-Hyeon Choung, Arthur Barakat

It has been claimed that video gamers possess increased perceptual and cognitive skills compared to non-video gamers. Here, we examined to which extent gaming performance in CS:GO (Counter-Strike: Global Offensive) correlates with visual performance.We tes ...
