Article Synopsis
  • The primate posterior parietal cortex (PPC) processes visual space for navigation, while the hippocampus (HPC) creates a memory-based map of the environment.
  • A study of macaques navigating a virtual maze revealed that neurons in both PPC and HPC showed spatial selectivity, indicating a link between visual cues and self-positioning.
  • Key neuron populations, responsive to saccades and fixations, contributed to navigation tasks, and both regions even anticipated landmarks before they became visible, suggesting a shared understanding of spatial layout.

To establish an overarching definition of what constitutes a sleep disorder, it is essential to know which health conditions should be included in the classifications of sleep disorders and to better distinguish the normal from the pathological in sleep medicine. This would bring together several professional organizations in their understanding of this hitherto heterogeneous concept. However, no consensus regarding a general definition of a sleep disorder currently exists.

Developing controlled and reproducible molecular assemblies incorporating lanthanide centers is a crucial step for driving forward up- and down-conversion processes. This challenge calls for the development of strategies to facilitate the efficient segregation of different Ln metal ions into distinct positions within the molecule. The unique family of pure [LnLn'Ln] heterometallic coordination compounds previously developed by us represents an ideal platform for studying the desired Ln-to-Ln' energy transfer (ET).

This review delves into the remarkable career and scientific contributions of Frans de Waal, a renowned figure in the field of ethology, primatology with important implications for the field of social neurosciences. Rooted in the Dutch tradition of ethology, influenced by luminaries like Niko Tinbergen and Jan Van Hooff, De Waal's career began with groundbreaking research on chimpanzees, which questioned long-held beliefs about dominance and aggression in animal behavior. His work, epitomized in his influential books, such as "Chimpanzee Politics", "The ape and the sushi master", "The age of empathy", not only revolutionized scientific thinking but also ignited discussions about empathy, morality, and complex cognitive functions in animals.

The concept of multimorbidity in psychiatry refers to the coexistence of multiple health conditions without conceptualizing a central disorder referring to a patient-centered approach that views every diagnosis equally. It emphasizes a shift from focusing on an index disorder to considering interrelated symptoms crucial in psychiatry due to frequent multimorbidity patterns. In clinical practice, multimorbidity guides patient-centered care helping to address the holistic needs of patients and challenging the organization of mental health care.

Infants' thoughts are classically characterized as iconic, perceptual-like representations. Less clear is whether preverbal infants also possess a propositional language of thought, where mental symbols are combined according to syntactic rules, very much like words in sentences. Because it is rich, productive, and abstract, a language of thought would provide a key to explaining impressive achievements in early infancy, from logical inference to representation of false beliefs.

One of the main goals for supporting people with a psychotic disorder is early detection and intervention, and the detection of Clinical High Risk (CHR) is a major challenge in this respect. This study sought to compare core symptoms of CHR for psychosis networks based on two CHR self-assessment tools, across different risk thresholds and age groups. This cross-sectional online investigation analyzed 936 individuals for CHR, in France and the UK, with the Prodromal Questionnaire-16 (PQ-16) and the Perceptual and Cognitive Aberrations (PCA).

Centre de Recherche en Cancérologie de Lyon, Inserm U1052, CNRS UMR 5286, Centre Léon Bérard, Université de Lyon, Lyon, France; Equipe Labellisée la Ligue Contre le Cancer, Lyon, France. Electronic address:

Article Synopsis
  • The ELN gene produces tropoelastin, crucial for forming elastic fibers that maintain tissue elasticity, and its decline is associated with aging and age-related diseases.
  • Decreased ELN levels in human and mouse fibroblasts lead to premature cellular senescence, but this process is linked to increased HMOX1 rather than direct elastic fiber degradation.
  • The study identifies a novel pathway where the decrease in ELN activates HMOX1 through transcription factors p53 and NRF2, resulting in iron accumulation and alterations in gene expression that promote senescence.

Article Synopsis
  • Staging and stratification challenge traditional views of disease by highlighting the gradual evolution of conditions and categorizing them based on specific markers, blurring the lines between normal and pathological states.
  • The paper focuses on oncology and psychiatry as two medical fields significantly influenced by these diagnostic approaches, revealing both conceptual and ethical issues that arise from their use.
  • It argues for a shift away from viewing diagnostic staging as strictly tied to time, instead promoting a blend of staging and stratification to improve clinical practice and better tailor interventions.

Service de Psychopathologie du Développement de l'Enfant et de l'Adolescent, Hospices Civils de Lyon, France; Institut des Sciences Cognitives Marc Jeannerod, UMR 5229 CNRS & Université Claude Bernard Lyon 1, France.

This Viewpoint explores challenges within the neurodiversity framework, with a particular focus on autism, and discusses three critical aspects: the risk of epistemic injustice, the balance between over and undermedicalization, and the terminological complexities associated with the "neuro-" prefix. It underscores the importance of a balanced approach that avoids overmedicalization while providing essential support, addresses concerns about the indiscriminate use of "neurodiverse", questions the terminology on neurodiversity, and suggests considering a broader term like "biopsychosocial diversity". Ultimately, this Viewpoint advocates for a measured approach to neurodiversity, emphasizing historical context and a diverse perspective to foster collaboration between cognitive science and behavior research.
