Mapping interactions between adversity and neuroplasticity across development
“Mapping interactions between adversity and neuroplasticity across development” Highlights: We propose a theoretical framework to formalize major ways in which experience (particularly adversity) interacts with neuroplasticity during human development. Adversity can uniquely influence neural circuitry depending on the state of neuroplasticity during the developmental timing of exposure (i.e., neuroplasticity as a moderator). Neuroplasticity is itself…

From Soundwaves to Brainwaves: “Music”
“From Soundwaves to Brainwaves: The Transformative Power of Music” The human brain physically embodies rhythmic sound in a remarkablesymphony that has the power to heal. People resonate to music. They respond positively in ways that suggest that the rhythms of the brain and body, like neurons, breathing, or cardiac rhythms, are engaged when you listen…

Blink and you see it
“Blink and you see it“ Every few seconds, our visual world disappears behind a thin fold of skin that maintains the tear film on the corneal surface and, for more than a tenth of a second, blocks light from falling onto the retina. “Blink and you miss it” is a common idiom that captures how…

The unbearable slowness of being …
The unbearable slowness of being: Why do we live at 10 bits/s? This article is about the neural conundrum behind the slowness of human behavior. The information throughput of a human being is about 10 bits/s. In comparison, our sensory systems gather data at ∼109 bits/s. The stark contrast between these numbers remains unexplained and touches…

Fast walkers have higher IQ and larger brains than slow walkers.
These findings are from a 5-decade cohort study of 904 participants in New Zealand published in @JAMANetworkOpen which tested the hypothesis that slow gait speed reflects accelerated biological aging at midlife. Slow gait was associated with multiple indices of compromised structural brain integrity, including smaller total brain volume, global cortical thinning, and reduced total surface…
