Background. Around half of patients presenting with EP will develop depressive symptoms.. Similarly, negative symptoms are highly prevalent (i.e. 51%) in EP and often run a chronic course. .

Understanding the mind not only requires a comprehension of the workings of low–level neural networks but also demands a detailed map of the brain’s functional architecture and a description of the large–scale connections between populations of neurons and insights into how relations between these simpler networks give rise to higher–level thought.
