In vivo whole-cortex marker of excitation-inhibition ratio indexes cortical maturation and cognitive ability in youth | PNAS
Studying E/I ratio development in vivo in humans is challenging due to limitations in noninvasive neuroimaging techniques. MR spectroscopy studies suggest changes in the balance of excitatory and ...

Quantifying the impact of air pollution from coal-fired electricity generation on crop productivity in India - PNAS
The negative impacts of air pollution on crop productivity have been quantified across a variety of pollutants, crops, and regions. The negative effect of ozone is particularly well-documented (10–20) ...

Modeling naturalistic face processing in humans with deep convolutional neural networks | PNAS
Faces in real life convey categorical attributes (e.g., age), unique identities, and dynamic information (e.g., expression, attention). Deep convolutional neural networks (DCNNs) can be trained to ...

Multiple sclerosis and gut microbiota: Lachnospiraceae from the ileum of MS twins trigger MS-like disease in germfree transgenic mice—An unbiased functional study | PNAS
We developed a strategy to identify gut bacteria functionally linked to the development of multiple sclerosis (MS). To minimize confounders, we analyzed microbiota composition in a large cohort of ...

A self-learning magnetic Hopfield neural network with intrinsic gradient descent adaption | PNAS
A milestone model in the field of machine learning is the Hopfield neural network (HNN) ().When originally proposed, the HNN features fully connected neurons which is the foundation of modern models ...

No evidence for Peto’s paradox in terrestrial vertebrates - PNAS
Briefly, Brownian motion is commonly used to describe the random evolution of traits through time. Specifically, changes in the value of a trait are drawn from a normal distribution with mean 0 and ...

Impairments in endogenous AMPA receptor dynamics correlates with learning deficits in Alzheimer’s disease model mice | PNAS
Dysregulation of AMPA receptors (AMPARs) contributes to a number of neurological and psychiatric disorders, including AD. However, studying longitudinal AMPAR changes in AD animals has been a big ...

The wooden artifacts from Schöningen’s Spear Horizon and their place in human evolution | PNAS
The earliest indirect evidence for human woodworking dates back 2 to 1.5 Ma ago based on use-wear on lithics (1, 2).Direct evidence of wood artifacts coming from Africa and the Middle East date back ...

Memory control deficits in the sleep-deprived human brain - PNAS
The adaptive benefits of memory suppression are associated with high-frequency heart rate variability (HF-HRV; 0.15 to 0.40 Hz)—a physiological correlate of cognitive control ().Specifically, higher ...

Inhibiting 15-PGDH blocks blood–brain barrier deterioration and protects mice from Alzheimer’s disease and traumatic brain injury | PNAS
Koh et al. show that 15-hydroxyprostaglandin dehydrogenase (15-PGDH) is pathologically elevated in human and mouse Alzheimer’s disease (AD), traumatic brain injury (TBI), and aging, with 15-PGDH ...
