The Mind and Depression
"A debate on Cartesian dualism has led to radically differing approaches to the treatment of depression." A new book reveals how much is at stake in our understanding of the mind.
"A debate on Cartesian dualism has led to radically differing approaches to the treatment of depression." A new book reveals how much is at stake in our understanding of the mind. "If consciousness and all its manifestations were 'merely' the firing of neurons and the release of chemicals in the brain, what need was there to focus on mental states? Once the physical brain was right, the rest would follow. It was an approach that has spawned a vast pharmaceutical industry to treat any pathological psychological state—anxiety, shyness, depression, psychosis—with a variety of pills."
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- Octopuses, like humans, have genes that seem to code for serotonin transporters.
- Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
- Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
