Lasers Used To Induce Gamma Brain Waves In Mice
Science Daily Sun, 26 Apr 2009 16:25 PM PDT
Scientists have studied high-frequency brain waves, known as gamma oscillations, for more than 50 years, believing them crucial to consciousness, attention, learning and memory. Now, for the first time, researchers have found a way to induce these waves by shining laser light directly onto the brains of mice. |
Brain Works Best When Cells Keep Right Rhythms, New Studies Suggest
Science Daily Sun, 26 Apr 2009 16:24 PM PDT
New research suggests that brain cells need to follow specific rhythms that must be kept for proper brain functioning. These rhythms don't appear to be working correctly in such diseases as schizophrenia and autism, and now Nature and Science demonstrate that precisely tuning the oscillation frequencies of certain neurons can affect how the brain processes information and implements feelings of ... |
