Experiences in the health services network and in the street: Captures and detours in psychology training for public health services.

This article discusses the internships at the psychosocial health system of Natal, Northeast region of Brazil, as part of training in psychology. The objective of these internships is to offer students work experiences in public health both inside and outside health services. Based on Institutional Analysis and Schizoanalysis, these experiences were examined through two analysers: (1) the power of knowledge and (2) the need for by-passes. We conclude that health provokes tensions between instituted practices in health services and those instituted in psychology training.
