Embryonic Eavesdropping: How Animals Hear and Respond to Sound
Recent findings buck the traditional idea that embryos are passive agents and instead suggest that by tuning into vibrations, organisms can better prepare to enter the outside world.

By measuring various pollutants in the immediate vicinity of pregnant women and tracking brain development of their children, researchers in Barcelona aim to untangle any influence the former has on the latter.
In mice, epigenetic marks made on histones during infancy influence depression-like behavior during adulthood. A drug that reverses the genomic tags appears to undo the damage.
Overactive immune cells identified in a mouse model and in postmortem human brain tissue may offer a potential therapeutic target for cognitive delays associated with the condition, researchers report.
Scans of eight fossilized adult and infant Australopithecus afarensis skulls reveal a prolonged period of brain growth during development that may have set the stage for extended childhood learning in later hominins.
Low doses of continuous penicillin exposure altered mouse pups’ microbiomes and gene expression in brain areas associated with emotional and cognitive function.
Juvenile birds learn the length of the sounds in a song from a false memory introduced via optogenetics, instead of from real interactions with a tutor bird.
Rhesus monkeys engineered to express a human gene reportedly show delayed brain development and better short-term memory. Fellow scientists are raising ethical red flags.
A study links having a male twin with women’s educational, financial, and childbearing decisions. Researchers suspect prenatal exposure to testosterone may play a role.
An analysis of the contours of more than 600 kids’ brains points to links between cerebral surface area and heritability in regions of the brain important in cognition.
Young rats injected with a synthetic cannabinoid have more of the brain’s motivating dopaminergic signaling and fewer numbers of inhibitory neurons than controls.
A longitudinal study tracking the progress of an epilepsy patient after surgery shows the brain’s ability to reorganize itself to function nearly normally.
