Training human volunteers to control their own brain activity in precise areas of the brain can enhance fundamental aspects of their visual sensitivity, according to a new study in the Journal of Neuroscience.
This non-invasive ‘neurofeedback’approach could one day be used to improve brain function in patients with abnormal patterns of activity, for example stroke patients. (more…)
*Electrical signals can’t shut off, suggest UCLA researchers*
Most of us know what it means when it’s said that someone is depressed. But commonly, true clinical depression brings with it a number of other symptoms. These can include anxiety, poor attention and concentration, memory issues, and sleep disturbances.
Traditionally, depression researchers have sought to identify the individual brain areas responsible for causing these symptoms. But the combination of so many symptoms suggested to UCLA researchers that the multiple symptoms of depression may be linked to a malfunction involving brain networks — the connections that link different brain regions.
