Detailed mapping of 1.2 million brain cells has revealed that not all cell types age in the same way and that some – found in a specific ‘hot spot’ – are more sensitive to the aging process. It opens ...

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 ...

The brain's immune system is getting attention at the Society for Neuroscience in Chicago. A lot of research is now focused on the interaction of neurons, glial cells and other immune cells. There's a ...

Neurons are the cells in the brain responsible for sending messages to the rest of the body, and scientists have long thought that they are settled into one subtype once they develop from stem cells, ...

Metastasis occurs when cancer cells break away from the original tumor and travel through the bloodstream to form new tumors in other parts of the body. It is the leading cause of cancer-related death ...

After nearly 350 years, a depiction of a bee’s brain is getting some buzz. A manuscript created in the mid-1670s contains the oldest known depiction of an insect’s brain, historian of science Andrea ...

Our nerve cells are surrounded by a protective layer (myelin). This protective layer allows signals to pass between cells incredibly quickly. But what happens when this layer goes missing from cells ...

A new study finds that mitochondria in our brain cells frequently fling their DNA into the cells' nucleus, where the mitochondrial DNA integrates into chromosomes, possibly causing harm. As direct ...

In a recent study published in the journal Nature, researchers developed spatial aging clocks using single-cell transcriptomics to explore cell-type-specific interactions and their impact on brain ...

The question of whether adult brains grow new brain cells has been debated for more than 60 years. Known as "neurogenesis", this process has been observed in the brain of other adult animals, yet its ...

Scientists at the University of Gothenburg have pinpointed a group of nerve cells in the brain stem that appear to be responsible for semaglutide’s appetite- and weight-controlling powers—without ...

Anxiety disorders are some of the most common mental health conditions in America, affecting about one in five people nationwide. But much remains unknown about the roots of anxiety in the brain. Now, ...
