Artificial Neural Nets Finally Yield Clues to How Brains Learn
The learning algorithm that enables the runaway success of deep neural networks doesn’t work in biological brains, but researchers are finding alternatives that could.
Brain’s ‘Background Noise’ May Hold Clues to Persistent Mysteries
By digging out signals hidden within the brain’s electrical chatter, scientists are getting new insights into sleep, aging and more.
Catherine Dulac Finds Brain Circuitry Behind Sex-Specific Behaviors
Catherine Dulac is overturning preconceptions about “male” and “female” instincts and opening new avenues to treating postpartum depression.
Brain Cell DNA Refolds Itself to Aid Memory Recall
Researchers see structural changes in genetic material that allow memories to strengthen when remembered.
Deep Neural Networks Help to Explain Living Brains
Deep neural networks, often criticized as “black boxes,” are helping neuroscientists understand the organization of living brains.
The Epigenetic Secrets Behind Dopamine, Drug Addiction and Depression
New research links serotonin and dopamine not just to addiction and depression, but to the ability to control genes.
Reasons Revealed for the Brain’s Elastic Sense of Time
New research finds that the subjective experience of time is linked to learning, thwarted expectations and neural fatigue.
Random Search Wired Into Animals May Help Them Hunt
The nervous systems of foraging and predatory animals may prompt them to move along a special kind of random path called a Lévy walk to find food efficiently when no clues are available.
Why Sleep Deprivation Kills
Going without sleep for too long kills animals but scientists haven’t known why. Newly published work suggests that the answer lies in an unexpected part of the body.
