Sexual dimorphism

The neural circuitry that coordinates mating and egg laying in female flies is identified.

The sexually dimorphic responses of male and female mice to their young are regulated by the activity of a specific population of neurons in the medial amygdala.

A recent study in Science reports the mechanism by which temperature affects sex determination in the red-eared slider turtle, Trachemys scripta elegans.

In recent years, several funding agencies have introduced requirements for researchers to consider sex as a biological variable in preclinical research. In this Comment article, McCarthy and colleagues discuss the potential impact of these policies for neuroscience research.
