Switching Brain Circuits On and Off Without Surgery
Researchers have developed a new, non surgical method to manipulate brain circuitry. The technique uses sound waves in combination with small bubble injections into the blood stream that temporarily opens the blood-brain barrier. ... Read More...
Chimpanzee Personality Traits Linked to Their Brain Structure
Researchers report personality traits in chimpanzees are correlated to the size of their hippocampus. The study reports greater hippocampal volume is linked to an increase in alpha behavior and decreased self regulatory function. ... Read More...
Brain Cell That Improves Learning Detected
