‘Understudied secret’ in brain dampens nicotine drive in mice
The interpeduncular nucleus produces an aversion to nicotine, even at low doses, and helps moderate how rewarding mice find the drug.

Lions and tigers and bears: Long-lived zoo animals offer a promising venue to study mental health and neurodegenerative disorders
These animals’ lifestyles often mirror those of people, making them a more relevant milieu than lab mice for determining how environmental factors influence mental health and cognitive decline. Studying them could improve animal welfare in the process.

Vasopressin boosts sociability in solitary monkeys
Inhaling the hormone did not increase aggression in unsociable rhesus macaques and appears to help the animals remember faces and reciprocate friendly behaviors.

Newfound gene network controls long-range connections between emotional, cognitive brain areas
The finding could help unravel gene regulatory networks and explain how genetic and environmental factors interact in neurodevelopmental conditions.

Should I stay (and eat) or should I go? How the brain balances hunger with competing drives
Understanding the interplay among rival signals, such as pain, thirst and fear, could provide insights into anxiety and other neuropsychiatric conditions.

Neurotransmitter switch-up helps fan extreme stress into full-blown fear
The flip occurs when certain neurons in the dorsal raphe start to express the chemical GABA instead of glutamate, a new study shows.

Temperament is innate but hackable, animal studies suggest
Emotional reactivity and vulnerability to stress are largely inherited in rodents — but can be modified in early life by targeting inflammation-related cells or even just adjusting an animal’s environment.

NIH autism database announcement raises concerns among researchers
The U.S. National Institutes of Health announced a plan to pour $50 million into data science projects intended to investigate the condition’s causes, but the initiative’s short timeline and other atypicalities have prompted questions.
