Abstract
A new cannula system is presented that allows intracerebral microinjec tions of neuroactive substances in freely moving rats in a social envi ronment. By connecting a microcannula to a freely rotating stainless s teel spring, small (0.2 mul) injections can be made without disturbing the ongoing social interaction. This microinjection system can be use d for instantaneous injections, but can also be used for microinfusion s during a considerable longer period of time.
