While selectively activating a neuron inside the brain, the researchers recorded the electrical activity of another neuron, to determine whether it received a signal, which would in turn indicate the ...

Older adults with exceptional memories continue to grow new brain cells. A recent study published in the journal Nature shows that this biological process nearly stops in people with Alzheimer's ...

A large barrier in neuroscience is the ability for researchers to conduct studies on a live, functioning brain without surgery or implanting probes. Today researchers at the Massachusetts Institute of ...

Brain cells are constantly swallowing material from the fluid that surrounds them - signaling molecules, nutrients, even pieces of their own surfaces - in a process known as endocytosis that is ...

Memories are thought to be stored in sparse groups of neurons called engrams. These are the cells that switch on during learning and can later switch on again during recall. In physiological aging and ...

Brain tumors do not just invade healthy tissue. They also physically squeeze it, and that mechanical compression may be enough to trigger neuron death in the surrounding brain. Two peer-reviewed ...

Researchers identify brain neurons that become active after exercise and help determine how much endurance improves with repeated training.

The human brain contains nearly 86 billion neurons, constantly exchanging messages like an immense social media network, but neurons do not work alone – glial cells, neurotransmitters, receptors, and ...

This discovery is important because it suggests a safer way to treat Alzheimer’s disease. Instead of trying to reduce ...

We’re not Barbie girls, but we live in a plastic world. Microplastics, tiny specks of broken-down plastic, are all around us. They hover in the air, float in our water, and are sprinkled in the food ...
