"Similarly, to understand consciousness, you have to go to the level of nerve cells," electrical impulse codes and brain networks.

An idea is currently debated that these types of processing are done by anatomically different brain networks.

The maps will also shed light on how brain networks are organized.

The brain networks of the person who sees a yawn by someone they care about may then become overstimulated and lead to a yawning response.

Psychiatric and neurological disorders can be characterized by connectivity within and between large-scale brain networks.

Recent work suggests that at least three large-scale brain networks are important in psychopathology:

Letter processing automatically recruits a multimodal brain network.

Alcoholism is associated with dampened activation in brain networks responsible for emotional processing, including the amygdala.

Still, greater understanding about the brain networks that underlie both addiction and eating disorders could have important implications for treatment.

Johnson specialises in the development of the brain networks subserving social cognition.
