Research image of serotonin and dopamine neurons manipulated simultaneously in mice.

Dopamine ‘gas pedal’ and serotonin ‘brake’ team up to accelerate learning

Mice learn fastest and most reliably when they experience an increase in dopamine paired with an inhibition of serotonin in their nucleus accumbens, a new study shows, helping to resolve long-standing questions about the neuromodulators’ relationship.

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.

Grant review needs reform. How about we add an element of chance?

A process that uses a lottery system saves time, reduces strategic resubmission and accepts that, above a quality threshold, luck has always played a part in science funding.
