New human neurons from adult cells right there in the brain

Researchers have discovered a way to generate new human neurons from another type of adult cell found in our brains. The discovery, reported in the October 5th issue of Cell Stem Cell, a Cell Press publication, is one step ...

Synapse 'protection' signal found; helps to refine brain circuits

The developing brain is constantly forming new connections, or synapses, between nerve cells. Many connections are eventually lost, while others are strengthened. In 2012, Beth Stevens, Ph.D. and her lab at Boston Children's ...

Identity crisis of satiety neurons leads to obesity

Obesity − as research in the past decade has shown − is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular ...

Why stress doesn't always cause depression

Rats susceptible to anhedonia, a core symptom of depression, possess more serotonin neurons after being exposed to chronic stress, but the effect can be reversed through amygdala activation, according to new research in the ...

High-speed microscope captures fleeting brain signals

Electrical and chemical signals flash through our brains constantly as we move through the world, but it would take a high-speed camera and a window into the brain to capture their fleeting paths.

Neuroscience

Inflammation signals induce dormancy in aging brain stem cells

In old age, the amount of stem cells in the brains of mice decreases drastically. The remaining ones protect themselves from completely vanishing by entering a state of dormancy, scientists from the German Cancer Research ...

Neuroscience

Research provides important insight on the brain-body connection

A study conducted by University of Arkansas researchers reveals that neurons in the motor cortex of the brain exhibit an unexpected division of labor, a finding that could help scientists understand how the brain controls ...
