Your brain can still make new neurons when you’re an adult. But how does the rare birth of these new neurons contribute to cognitive function? Researchers know that new neurons contribute to memory ...

Our brain is a complex organ. Billions of nerve cells are wired in an intricate network, constantly processing signals, enabling us to recall memories or to move our bodies. Making sense of this ...

The next time you reach for a memory or make a quick choice, a storm of tiny signals races through your brain. Scientists can ...

This confocal microscope image shows midbrain neurons (red) co-expressing the mu-opioid receptor (Oprm1, white) and cannabinoid receptor 1 (Cnr1, green). The interaction of these two reward pathways ...

An Indian-origin Harvard professor, Aravinthan Samuel, is revolutionizing brain mapping with SmartEM, an AI-powered system.

Recording electrical signals from inside a neuron in the living brain can reveal a great deal of information about that neuron's function and how it coordinates with other cells in the brain. However, ...

Your brain can still make new neurons when you’re an adult. But how does the rare birth of these new neurons contribute to cognitive function? Researchers know that new neurons contribute to memory ...

In the late 1800s, Spanish neuroscientist Santiago Ramón y Cajal drew hundreds of images of neurons. His exquisite work influenced our understanding of what they look like: Cells with a bulbous center ...

In the 1970s, scientists from several countries proposed to reconstruct, one by one, all the neurons in the brain as they appear under an electron microscope. They started with a small worm.

Illuminating the dark. Tavakoli, Lyudchik, and Danzl discuss a close-up image of the hippocampus—a brain region responsible for memory formation and spatial navigation—in the microscopy room at the ...
