(Medical Xpress)—When something bad happens to otherwise healthy neurons it's easy to blame the usual suspects—the mitochondria. In some cases the nucleus might be the one at fault, as in a de novo mutation in a critical ...
(Medical Xpress)—Among the many great talks at the recent annual meeting of the Society for Neuroscience were three special lectures given sequentially during the evenings. The first described how we might translate the ...
(Medical Xpress)—Regulating the distribution of power in neurons is done by a system that makes the national electric grid look simple by comparison. Each neuron has several thousand mitochondria confined into narrow neuritic ...
Epilepsy, one of the most common neurological disorders, is characterized by the spontaneous repetition of seizures caused by the hyperactivity of a group of neurons in the brain. Could we therefore reduce neuronal hyperactivity, ...

Columbia neuroscientists have discovered why mitochondria, tiny power generators that keep our cells healthy, are often strangely shaped inside the brain. Mitochondria, which exist by the thousands in each of our body's 37 ...
