Ivan Antonio Izquierdo Gobic, Argentine-born Brazilian neurobiochemist (Buenos Aires 16 September 1937 - Porto Alegre 09 February 2021)

Son of Croatian mother
 
ACHIEVEMENTS
Internationally respected as world leader in memory physiology 
 
Discovered neurohumoral and hormone mechanisms  that regulates formation, evocation, persistence and extinction of memory  
 
Obtained the memory solidification map
 
Determinated the cascade of biochemical events in hippocampus and in other brain structures required to memories formation 
 
Discovered functional, anatomical and molecular separation between short term and long term memories (1998) and the endogenous state dependence as a key regulator in memory and brain functioning  
 
Discovered the key role of neurotrophic factors and ubiquitine/proteasome system in hippocampus for memory formation (2001-6)

With J. Medina, M. Cammarota, J. Rossato & B. Bevilaqua discovered brain mechanism via dopamine that controls the persistence of recollections in the memory (2009)

With J. Miskiw & C. Furini discovered a hippocampal mechanism that causes fear memory extinction (2014)
 

Held about 23,000 citations
