Diverse photographs of human faces against their natural background trigger a specific electrical response in the right hemisphere of the brain in infants aged 4–6 months.

Infants' vocalisations are contingent on their own stress physiology, and alter the inter-personal dynamics of how stress states are shared across the infant-caregiver dyad.

More parent-reported infections in the first year of life were associated with metabolic differences linked with cardiovascular and metabolic disease in adulthood, with observational evidence for inflammation partly mediating this relationship.

Unprecedented 4D spatiotemporal infant regional cerebral blood flow framework and region-specific physiology–function coupling across infancy were elucidated, highlighting strong physiology–function coupling specifically at the default-mode network to meet extraneuronal metabolic demand for network emergence.

Greater connectivity of the descending pain modulatory system network in the infant brain is associated with lower pain-related brain activity.

Human infants can use various muscle activations as soon as birth to produce rhythmic leg movements, but the strategy underlying this variable output seems to change between the first months of life and toddlerhood.

A post-lysosomal cholesterol transport inhibitor reveals how the endoplasmic reticulum membrane regulates total cellular cholesterol by constantly monitoring a critical pool of cholesterol in the plasma membrane.

Mandrill mothers know best because they use their offspring’s facial resemblance with other infants to guide their social opportunities towards similar-looking ones as an adaptive maternal behavior.

Six- to twelve-month old infants, who have little linguistic or object experience, classify objects by relying on a invariant representation of global shape known as the shape skeleton.

The newborn infant experience of pain closely resembles that observed in adults, suggesting that infants have the sensory and emotional capacity to experience pain.
