Exposing rats to acute stress increased the generation of new neurons in a subregion of the hippocampus, and improved the animals' performance in a memory task two weeks later.

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

Five mouse models of autism show deficits in delay eyeblink conditioning, a form of split-second sensory learning that involves the cerebellum, a frequent site of disruption in autistic brains.

A single night of sleep deprivation suppresses fighting behaviors in male fruit flies, with consequent impairments in reproductive fitness.

White matter microstructure in hemianopia patients indicates that blindsight requires an intact connection between the lateral geniculate nucleus and extrastriate cortex.

Local elimination of acetylcholine synthesis in habenular neurons demonstrates a key role for vesicular synergy and neurotransmitter co-release in nicotine dependence.

High-resolution imaging shows that the different columns of the human periaqueductal gray play differential roles in the response to a respiratory threat.

Mechanistically distinct COX-2 inhibitors reduce stress-induced behavioral pathology via unique multimodal molecular mechanisms, and could be used to treat mood disorders.

Perception is proposed to be a dynamic motor-sensory closed-loop process in which information flows through the environment and the brain in continuous loops, converging towards steady-state percepts.

While the striatum and orbitofrontal cortex learn about threats through verbal warnings, the amygdala learns only from direct experience, suggesting that the amygdala forms part of a specialized threat detection system.
