Schizophrenia Brain Fault 'Found'

Scientists say they have identified faulty brain waves that may explain the symptoms of schizophrenia.

When the researchers looked at the brain wave patterns they found the patients with schizophrenia showed no activity in a certain wave band when performing the button-pushing task.

However, the healthy volunteers had visible gamma wave activity, indicating that their brains were processing the visual information to guide their response.

"If the most efficient communication between assemblies of neurons is at 40 hertz, and the schizophrenics are using a lower frequency, it's likely they have defective communication between cell assemblies and brain regions."

"If you know the neurochemical identity of the neurons and synapses involved in generating gamma activity, you can try to target treatments toward them."
