[2] He studied for a medical degree at the Faculty of Medicine of the Universidad Nacional de Rosario, as did his wife Lily Bleger (née Storch).

Around 1947 the Blegers moved to Santiago del Estero, and started to live in La Banda, one of the poorest districts of the province at the time.

Bleger frequently left Santiago del Estero to receive training in other disciplines, such as reflexology, a Pavlovian form of psychology, which he was introduced to by the Russian emigrant Konstantin Gavrilov, in Tucumán.

The Blegers became increasingly interested in psychoanalysis, and began to commute to Buenos Aires to receive training, where they settled in 1954.

He was eventually ousted from the party over his work on psychoanalysis and Marxism, as well as his rejection of the Soviet Union's model of communism in the late 50s.

In 1962 he became a professor of mental hygiene at the UBA, and continued to practice as a psychoanalyst in Buenos Aires until his death on June 20, 1972.

[2] Central points of reference for Bleger were Hegel, Marx, Sartre, Klein, and Georges Politzer.

His work is an extension of Kleinian metapsychology, and in constant dialogue with its central figures, such as Bion, Rosenfeld, or Klein herself.

The term's two components are the Greek words for viscous (γλισχροσ) and for kernel or nucleus (καρυον).

[7] The glischro-caric position is characterized by "an agglutinated object relation, catastrophic anxiety, and defences such as splitting, projection and immobilization, functioning with maximum intensity, massivity and violence.

"[8] The paranoid-schizoid position is reached through "progressive fragmentation and discrimination inside the agglutinated object, which coincides with a gradation of splitting and projection."

Ambiguity is part of the primitive mental situation, and is overcome through various forms of projective identifications, for which Bleger frequently uses the term "depositary" and "deposited", a distinction he borrows from Enrique Rivière.

[13] In the clinical setting the nucleus appears as part of a psychotic transference, in which the analysand seeks to symbiotically merge with the analyst through massive projective identification.
