All Is Relative—A Call for Considering “Physiologically Informed” Control Conditions to Improve the Mechanistic Understanding of the Effects of Physical Exercise on Cognition

Scandinavian Journal of Psychology, EarlyView.
ABSTRACT There is a growing interest in elucidating the mechanisms that drive the benefits of physical exercise on cognitive performance. A key element for a better understanding of a particular phenomenon (e.g., the mediators of the exercise‐cognition interaction) is the selection of an appropriate control condition/group as the basis for causal ...

Distinctive neurophysiological correlates of sound onset and offset perception in humans

The Journal of Physiology, EarlyView.
Abstract figure legend Electroencephalography (EEG) recordings were obtained from participants listening to successive pairs of 1‐2 s noises in a silent background (Study 1) or successive pairs 1‐2 s silent gaps in a noise background (Study 2). Participants heard the same stimuli in the context of either a duration discrimination task (identifying ...

Distinct Temporal Stages of Infant Brain Processing Associate With Early Versus Later Autism Diagnosis

Developmental Science, Volume 29, Issue 5, September 2026.
ABSTRACT The expression of autism traits sufficient to meet criteria for a diagnosis can occur early (by 3 years) or later (from mid‐childhood onwards). It remains unknown whether variation in age of onset is due to clinical recognition or reflects distinct biological pathways.

Human T-cell leukemia virus type I Tax associates with and is negatively regulated by the NF-kappa B2 p100 gene product: implications for viral latency. [PDF]

Molecular and Cellular Biology, 1994
Human T-cell leukemia virus type I (HTLV-I) is the etiologic agent of the adult T-cell leukemia, an aggressive and often fatal malignancy of activated human CD4 T cells. HTLV-I encodes an essential 40-kDa protein termed Tax that not only transactivates the long terminal repeat of this retrovirus but also induces an array of cellular genes. Tax-mediated

CLRN1 Variants in Müller Cells Cause Mitochondrial Dysfunction in USH3A Retinal Organoids

CNS Neuroscience &Therapeutics, Volume 32, Issue 8, August 2026.
We generated retinal organoids from a patient with USH3A and performed single‐cell RNA sequencing. CLRN1 was specifically expressed in Müller cells, where its variants led to mitochondrial dysfunction and photoreceptor degeneration. ABSTRACT Background Usher syndrome 3A (USH3A), caused by mutations in the CLRN1 gene, leads to retinitis pigmentosa and ...
