Animal behavior is shaped by a variety of" internal states"—partially hidden variables that
profoundly shape perception, cognition, and action. The neural basis of internal states, such …

Goal-directed social behaviours such as mating and fighting are associated with scalable
and persistent internal states of emotion, motivation, arousal or drive. How those internal …

The ventrolateral subdivision of the ventromedial hypothalamus (VMHvl) contains∼ 4,000
neurons that project to multiple targets and control innate social behaviors including …

Neurons transmit information to distant brain regions via long-range axonal projections. In
the mouse, area-to-area connections have only been systematically mapped using bulk …

Parental care is essential for the survival of mammals, yet the mechanisms underlying its
evolution remain largely unknown. Here we show that two sister species of mice …

INTRODUCTION Affective or metabolic states, such as anxiety, stress, or thirst, enable
adaptations of perception and the selection of appropriate behaviors to achieve safety or …

In the face of starvation, animals will engage in high-risk behaviors that would normally be
considered maladaptive. Starving rodents, for example, will forage in areas that are more …

How brains are hardwired to produce aggressive behavior, and how aggression circuits are
related to those that mediate courtship, is not well understood. A large-scale screen for …

Abstract 'Sundowning'in dementia and Alzheimer's disease is characterized by early-
evening agitation and aggression. While such periodicity suggests a circadian origin …

Type 1 estrogen receptor-expressing neurons in the ventrolateral subdivision of the
ventromedial hypothalamus (VMHvlEsr1) play a causal role in the control of social …
