Where in the Brain does Creativity come from? Evidence from Jazz Musicians

Brain activity maps showing areas associated with high-creativity performances compared with lower-creativity performances. Each map shows a top view of the head.

A new brain-imaging study has studied the brain activity of jazz guitarists during improvisation to show that creativity is, in fact, driven primarily by the right hemisphere in musicians who are comparatively inexperienced at improvisation. However, musicians who are highly experienced at improvisation rely primarily on their left hemisphere.

This suggests that creativity is a “right-brain ability” when a person deals with an unfamiliar situation but that creativity draws on well-learned, left-hemisphere routines when a person is experienced at the task.

By taking into consideration how brain activity changes with expe...

Repairing Stroke-Damaged Rat Brains

Researchers at Lund University in Sweden have succeeded in restoring mobility and sensation of touch in stroke-afflicted rats by reprogramming human skin cells to become nerve cells, which were then transplanted into the rats’ brains. The study has now been published in the Proceedings of the National Academy of Sciences (PNAS).

“Six months after the transplantation, we could see how the new cells had repaired the damage that a stroke had caused in the rats’ brains,” says Professor Zaal Kokaia, who together with senior professor Olle Lindvall and researcher Sara Palma-Tortosa at the Division of Neurology is behind the study.

Several previous studies from the Lund team and others have shown that it is possible to transplant nerve cells derived from human stem cells or from reprog...

Researchers use Nanotechnology to develop new Treatment for Endometriosis

Scientists have developed a precise, nanotechnology-based treatment to alleviate the pain and fertility problems associated with endometriosis, a common gynecological condition in women of childbearing age.

Research led by Oleh Taratula of the Oregon State University College of Pharmacy and Ov Slayden of the Oregon National Primate Research Center at Oregon Health & Science University used photo-responsive nanoparticles loaded with dye to find and remove the lesions associated with the disorder.

The endometrium is the innermost layer of the uterus, and endometriosis occurs when endometrium-like tissue forms lesions outside of the uterine cavity—usually involving the ovaries, the fallopian tubes and the tissue lining the pelvis.

On rare occasions, en...

Brown Fat can Burn Energy in an unexpected way

FGF6 and FGF9 regulate UCP1 expression independent of brown adipogenesisNature Communications, 2020; 11 (1) DOI: 10.1038/s41467-020-15055-9

Researchers have discovered an unexpected biological pathway by which brown fat cells can translate energy into heat. When we are exposed to sufficient cold or exercise, small clusters of brown fat cells in our bodies begin to burn up energy. Since 2009, when researchers at Joslin Diabetes Center and other institutions discovered that this helpful form of fat can be active in adults, scientists have sought to turn up the heat from these cells to treat obesity, diabetes and other metabolic conditions.

Researchers in the lab of Joslin’s Yu-Hua Tseng, PhD, a Senior Investigator in the Section on Integrative Physiology and Metabolism, now have dis...
