Sex hormone boosts female rats’ sensitivity to unexpected rewards
During the high-estradiol stages of their estrus cycle, female rats learn faster than they do during other stages—and than male rats overall—thanks to a boost in their dopaminergic response to reward, a new study suggests.

‘What Is Intelligence?’: An excerpt
In his new book, published today, Blaise Agüera y Arcas examines the fundamental aspects of intelligence in biological and artificial systems. In this excerpt from Chapter 4, he examines temporal difference, a reinforcement learning algorithm.

New dopamine sensor powers three-color imaging in live animals
The tool leverages a previously unused segment of the color spectrum to track the neurotransmitter and can be used with two additional sensors to monitor other neurochemicals at different wavelengths.

Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

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.

Newly characterized striatal circuits add twist to ‘go/no-go’ model of movement control
The two novel pathways control dopamine release in opposing ways and may link motivation and mood to action, a new study shows.

Alex Maier argues that a scientific explanation of consciousness requires grounding in formalized mathematics
When it comes to discovering laws of nature for consciousness similar to those in physics, Maier argues that integrated information theory is the only game in town.
