Brains also have supply chain issues—blood flows where it can, and neurons must make do with what they get

Neuroscientists have long assumed that neurons are greedy, hungry units that demand more energy when they become more active, and the circulatory system complies by providing as much blood as they require to fuel their activity.

Alzheimer's disease: Problems with the brain's energy supply could be a cause

Scientists have been working to understand the root causes of dementia and Alzheimer's disease for decades now. But one of the reasons we don't yet have a cure for this disease is because of the complexity of the human brain—alongside ...

Sex-specific differences seen in response to reduced insulin activity

Insulin is not only a regulator of blood sugar, but also has an influence on life expectancy. If the insulin signaling pathway is inhibited, animals live longer. But which tissue is crucial for this? And do males and females ...

Myelin determines energy metabolism in inhibitory brain cells: Study

Researchers at the Netherlands Institute for Neuroscience have discovered that the energy management of inhibitory brain cells is different than that of excitatory cells in our brain. Why is that the case and what is the ...
