Schizophrenia brain changes 'due to disease rather than genes’

The brain abnormalities observed in patients with schizophrenia are primarily due to processes associated with the disease itself or its treatment, as opposed to being caused by genetic factors, the results of a Dutch study indicate.

MEG-MRI combined device for mapping the human brain

Researchers at Aalto University in Finland have developed the world's first device designed for mapping the human brain that combines whole-head magnetoencephalography (MEG) and magnetic resonance imaging (MRI) technology. MEG measures the electrical function and MRI visualizes the structure of the brain. The merging of these two technologies will produce unprecedented accuracy in locating brain electrical activity non-invasively.

Impaired frontostriatal circuitry linked to cognitive defects in PD

Reduced activation of the frontostriatal circuits may underlie the mild cognitive impairment often seen in patients with early Parkinson’s disease, say researchers.
