The researchers traced the output of those cells to the hypothalamus, which is known to control behaviors associated with anxiety (in people, those include increased heart rate, avoidance, and secretion of stress hormones).
Next, they hope to study exactly how PER1 controls appetite and eating behavior — whether its molecular actions work through the liver, fat cells, brain or other organs.
The wiring diagrams look like colorful threads on a tapestry, and they're clear enough to show which cell clusters control specific behaviors.
The team led by Rory Fisher, Ph.D., professor of pharmacology in the UI Carver College of Medicine, has identified a protein called RGS6 (regulator of G protein signaling 6) that acts through two separate mechanisms to control alcohol - seeking behavior and alcohol - induced cell death in heart, liver, and other organs.
The first genetically encoded optical tool that can precisely control brain cells (neurons) by the millisecond, optogenetics allows for light - induced control of neuronal activity, helping researchers understand how neurons form circuits that control behavior.
It is an enormously complicated and interdependent set of controls, still poorly understood to be sure, but the ability to change protein levels is in principle the ability to change cell behavior.
