Rat neurons thrive in a mouse brain world, testing ‘nature versus nurture’
Neurons from the two rodents can wire up together to form functional circuits—all while maintaining some species-specific properties, two new studies show.

Cocaine, morphine commandeer neurons normally activated by food, water in mice
Confirming a long-held hypothesis, repeated exposure to the drugs alters neurons in the nucleus accumbens, the brain’s reward center, and curbs an animal’s urge for sustenance.

Drafting a ‘dysfunctome’: Faulty connections to subthalamic nucleus characterize disparate brain disorders
Different circuits between the millimeters-wide structure and the cortex go awry in Tourette syndrome, obsessive-compulsive disorder, dystonia and Parkinson’s disease, a new study of human brain scans suggests.

Newly found hypothalamus circuits shape bullying behaviors in mice
Activity in the tiny brain region helps submissive rodents learn to avoid aggressors, and aggressive mice to curb their attacks, according to two recent studies.

Mutation in top autism-linked gene may alter eye reflex
The discovery could help clinicians diagnose children who carry mutations in the gene, called SCN2A, and gauge their responses to potential therapies.

In hot water: Climate change tests limits of neuronal resilience in crabs
Warming seas disrupt the function of neurons — and could seed permanent changes in marine species, according to studies of a circuit that controls digestion in crustaceans.

Women are systematically under-cited in neuroscience. New tools can change that.
An omitted citation in a high-profile paper led us to examine our own practices and to help others adopt tools that promote citation diversity.
