Susceptibility of Glucose Regulation to Social Isolation

This study shows that social isolation causes fasting hyperglycemia in male mice, which is mediated by testicular hormones and glucoregulatory brain neurons, but not in females.

Hypothalamic Vasopressin Neurons Enable Maternal Thermoregulatory Behaviors

This study shows that vasopressin neurons in the hypothalamus regulate maternal thermoregulatory behaviors in mice, influenced by ambient temperature and TRPM8 thermosensation.

Evaluating sickness-induced anxiety versus lethargy at the behavioral and neuronal activity level

This study distinguishes sickness-induced lethargy from anxiety in mice using behavioral tests and neuronal activity analysis, finding increased lethargy but not anxiety.

Oxytocin Neurons Enable Social Transmission of Maternal Behavior

The paper shows that social interactions between mother mice and virgin mice activate oxytocin neurons, enabling the virgins to acquire maternal behavior through social transmission.
