One of the most influential contributions of machine learning to understanding the human brain is the (fairly recent) formulation of learning in real world tasks in terms of the computational ...

Researchers have successfully altered human reward learning using non-invasive transcranial ultrasound stimulation directed at a deep brain structure linked to motivation.

Understanding the underlying biological mechanisms of human and animal behavior can help advance critically important industries such as medicine, healthcare, robotics, artificial intelligence (AI), ...

Researchers have demonstrated that brain cells learn faster and carry out complex networking more effectively than machine learning by comparing how both a Synthetic Biological Intelligence (SBI) ...

The psychologists examined how gamblers plan their actions to maximize rewards -- how their so called reinforcement learning works. In the study, participants had to decide between already proven ...

John Schulman cofounded the ambitious software company OpenAI in December 2015, shortly before finishing his Ph.D. in electrical engineering and computer sciences at UC Berkeley. At OpenAI, he led the ...

A small region of the brain, known as the ventral tegmental area (VTA), plays a key role in how we process rewards. It produces dopamine, a neuromodulator that helps predict future rewards based on ...

A new study on laboratory rats has found that the brain’s ability to learn from rewards is enhanced by the hormone estrogen. The work shows that naturally cycling estrogen levels alter the brain’s ...

In their pursuit of maximum reward, people suffering from gambling disorder rely less on exploring new but potentially better strategies, and more on proven courses of action that have already led to ...
