Connecting neurons to fix the brain
Each of the brain's 100 billion neurons forms thousands of connections with other neurons. These connections, known as synapses, allow cells to rapidly share information, coordinate their activities, and achieve ...

Excitation and inhibition remain balanced, even when the brain undergoes reorganization
Every second, the brain's nerve cells exchange many billions of synaptic impulses. Two kinds of synapses ensure that this flow of data is regulated: Excitatory synapses relay information from one cell to the next, while inhibitory ...

Sensory experience and rest control survival of newborn neurons in adults
When it comes to the circuits that make up the olfactory system, it seems that less is more. Much like the addition and elimination of extra synapses that helps fine-tune brain circuitry, the olfactory system continues to ...

Research finds enzyme disrupting nerve cell communication in Alzheimer's disease
Alzheimer's disease is characterized by abnormal proteins that stick together in little globs, disrupting cognitive function (thinking, learning, and memory). These sticky proteins are mostly made up of beta-amyloid ...

Gardening in the brain: Specialist cells prune connections between neurons
Gardeners know that some trees require regular pruning: some of their branches have to be cut so that others can grow stronger. The same is true of the developing brain: cells called microglia prune the connections ...

Even in fruit flies, enriched learning drives need for sleep
Just like human teenagers, fruit flies that spend a day buzzing around the "fly mall" with their companions need more sleep. That's because the environment makes their brain circuits grow dense new synapses and they need ...
