Brain Chemical Helps Signal to Neurons When to Start a Movement
Dopamine, a neurochemical often associated with reward behavior, also seems to help organize precisely when the brain initiates movements. It’s the latest revelation about the power of neuromodulators.
AI Overcomes Stumbling Block on Brain-Inspired Hardware
Algorithms that use the brain’s communication signal can now work on analog neuromorphic chips, which closely mimic our energy-efficient brains.
New Map of Meaning in the Brain Changes Ideas About Memory
Researchers have mapped hundreds of semantic categories to the tiny bits of the cortex that represent them in our thoughts and perceptions. What they discovered might change our view of memory.
Neural Noise Shows the Uncertainty of Our Memories
The electrical chatter of our working memories reflects our uncertainty about their contents.
