comparison of fetal/newborn brain scans and reconstructed surfaces of swollen physical gels for humans, ferret, and macaque models.

How do brains fold? By combining MRI scans, soft gel experiments, computer simulations, physics and mathematics, researchers from the lab of L. Mahadevan studied brain development and mistakes therein, using data from ferrets, macaques, and humans. Their work shows that a simple physical mechanism—faster growth of the cortex relative to deeper tissue—can explain both normal brain folding across species and in some developmental brain disorders.

Host-microbe interactions are essential for neurological function. Valentina Lagomarsino shares new research from the Rao Lab showing how microbes play a vital role in regulating the neuroendocrine axis and activity of motor circuits in the colon.

Amar Sahay shares his lab’s discovery that many ultra-high confidence risk genes for autism, bipolar disorder, schizophrenia, and epilepsy may be regulators of experience-dependent plasticity of inhibitory neurons in the hippocampus of adult mice. Proof-of-concept experiments reveal that targeting one of these regulators can improve cognition and suppress seizures in a common mouse model of neurodevelopmental disorder risk.

Nuria Domínguez-Iturza and Paola Arlotta present new research describing the molecular signals that promote myelination in the cerebral cortex and show that these signals are expressed at varying levels across neuronal types. Their findings reveal how neuronal diversity shapes myelin development, providing new insights into brain development and disease.

George Church and colleagues, co-first authors Alexandru M. Plesa and Sascha Jung, have developed a new method for predicting tissue age and screening for genes that affect the aging process, offering a new way to search for genetic factors that could be manipulated to turn back the clock on aging cells and rejuvenate tissue.

Amid the increasing prevalence of Alzheimer’s disease and related dementias (ADRD), Chirag Patel, Peng Gao, Chenshuang Li and colleagues have conducted what they describe as the most extensive systematic evaluation to date of associations between ADRD and nearly 200 environmental exposures — from pollution to diet to social connection.

Wade Regehr and colleagues have identified a wealth of new cell types that appear to work together in unexpected ways. By deepening understanding of the cerebellum’s structure and function, these findings could set the stage for developing new treatments for neurological disorders in which the cerebral cortex goes awry, including ataxia, depression, anxiety, sleep disorders, and cognitive or executive impairments.
