On March 5th 2018, our colleague Ruth Gorenberg was invited by the Lacanian Clinic of Care and Research in Psychoanalysis (CLIPP) to deliver the Opening Conference of the Psychoanalysis Course “Os casos clínicos de Freud e o ensino de Lacan”, which was entitled "Voice and Psychosis". This event was presented by Marizilda de Oliveira Paulino. Radio Lacan would like to thank Carmen Silvia Cervelatti and Marizilda de Oliveira Paulino for recording this event.
