"I’m a pathologist, which means that I run the lab, and I’m continually shocked by all the unnecessary lab work that comes my way. Doctors have to find something wrong with you, because preventative measures aren’t sexy. They know that you’re more likely to appreciate them if they tell you something’s wrong, than if they tell you to stop drinking 40 oz sodas."
Researchers Show How Lost Sleep Leads to Lost Neurons
First report in preclincal study showing extended wakefulness can result in neuronal injury.
Most people appreciate that not getting enough sleep impairs cognitive performance. For the chronically sleep-deprived such as shift workers, students, or truckers, a common strategy is simply to catch up on missed slumber on the weekends. According to common wisdom, catch up sleep repays one’s “sleep debt,” with no lasting effects. But a new Penn Medicine study shows disturbing evidence that chronic sleep loss may be more serious than previously thought and may even lead to irreversible physical damage to and loss of brain cells. The research is published today in the Journal of Neuroscience.

Axons (brown) of nerve cells are surrounded by insulating cells called the myeline sheet (purple). These allow for more efficient conduction of nerve impulses along these huge cells. The sciatic nerve in mammals goes from the base of the spine, to the bottom of your feet. These cells can reach up to more than a meter depending on how tall you are. The perinuerium is the connective tissue (blue) that surrounds the structure.
