• Dopamine neurons factor ambiguity into predictions enabling us to 'win big and win often'

  09-03-2017 20:23
  In the struggle of life, evolution rewards animals that master their circumstances, especially when the environment changes. The recipe for success is: win big, and win often. Success depends on the ability to learn. Researchers describe how dopamine-releasing neurons, which produce teaching signals for the brain, weigh the ambiguity of sensory information when they assess how successfully past experiences have guided a new decision. These neurons are even more sophisticated than previously thou

• Researchers discover how neurons tell each other to die under trauma, disease

  09-03-2017 20:22
  Neuroscientists have found that healthy neurons receive messages from injured neighbors that can lead to death. If they can block these messages from getting through, they may be able to slow the progress of neurodegenerative diseases.

• Social phobia: Indication of a genetic cause

  09-03-2017 18:06
  People with social anxiety avoid situations in which they are exposed to judgment by others. Those affected also lead a withdrawn life. Researchers have now found evidence for a gene that is believed to be linked to the illness. It encodes a serotonin transporter in the brain. Interestingly, this messenger suppresses feelings of anxiety and depressiveness.

• Machine learning writes songs that elicits emotions from its listeners

  09-03-2017 18:06
  Music, more than any art, is a beautiful mix of science and emotion. It follows a set of patterns almost mathematically to extract feelings from its audience. Machines that make music focus on these patterns, but give little consideration to the emotional response of their audience. Scientists have developed a new machine-learning device that detects the emotional state of its listeners to produce new songs that elicit new feelings.

• Neuroscientists pinpoint key gene controlling tumor growth in brain cancers

  09-03-2017 18:05
  Investigators have identified a stem cell-regulating gene that affects tumor growth in patients with brain cancer and can strongly influence survival rates of patients. The findings could move physicians closer to their goal of better predicting the prognosis of patients with brain tumors and developing more personalized treatments for them.
