In a recent study published in Autism Research, researchers at the University of Miami and Harvard Medical School suggest that newborn auditory brainstem response (ABR) screening results may be used as a biomarker for autism spectrum disorder (ASD) (Miron et al, 2020).
When examining ABR data from 139,154 newborns, the 321 newborns later diagnosed with ASD displayed greater variability and significant prolongations of the negative wave that follows positive wave V (V-negative) and ABR phase calculated with a Fast Fourier Transform.
The delayed ABR latencies in the present study are similar to those reported in previous studies of older infants and children tested with higher-intensity stimuli (Fujikawa‐Brooks et al, 2010; Miron et al, 2016, 2018; Roth et al, 2011; Wong and Wong, 1991).
Given the availability of newborn hearing screening data, the results of this study are important. However, future studies will be necessary to replicate this work and to determine the usefulness of the ABR phase and V-negative. The authors conclude that future studies using higher stimulus intensities will likely yield less variable results and offer a more robust biomarker for diagnosing ASD in infants.

If you have a dog or cat, you’ve probably seen their ears moving toward an interesting or startling sound. For professional equestrians, watching the ears of their horse allows them to gauge their shifting attention. Humans still have these same muscles, and even more interesting is their relationship to our brain and how we pay attention. …
Tai Chi is not just for increasing balance; it may also help improve cognitive performance. In a recent randomized controlled trial, study participants who practiced a form of Tai Chi twice a week for six months improved their scores on the Montreal Cognitive Assessment (MoCA) when compared to a control group (Fuzhong et al, 2023)….
The majority of people are familiar with earthquakes, but there is another phenomenon that is not nearly as predictable, and louder—skyquakes. Skyquakes are enigmatic sounds, typically described as a very loud boom or trumpet-sounding noise that has no apparent cause and seems to come from the sky. Their sound is like distant, but very loud, thunder with…
