SCIENTIFIC RESEARCH
NEUROCHEMISTRY OF MEMORY LABORATORY

“Learning and memory are part of the very foundation of our lives. We tend to think of memory as involving only our past, but in fact, it is memory that allows us to use past experience to think, reason and plan for the future – without memory the continuity between past, present and future that we take for granted is lost”. CNLM at UCI.

My work is to investigate memory at neurochemical brain systems level trying to contribute to the question of how we learn and remember; my main research topics are:

FORMATION OF AVERSIVE AND INCIDENTAL MEMORIES: CORTICAL, LIMBIC AND BASAL BRAIN INTERACTIONS: Our research is aimed at gaining knowledge about the mechanisms of chemical communication between brain structures that interact during aversive memory formation, as well as those without an evident emotional component, by using non-associative and associative taste and context learning models and manipulating the different structures involved in forming and retrieving memory. Behavioral, pharmacological and neurochemical findings to date indicate that complex structural and chemical interactions between cortical, basal and limbic areas of the brain occur during the acquisition, consolidation and evocation of memories. These studies are helping to better understand the similarities and differences in how memories of different types and strengths are processed.

NEUROBIOLOGICAL SUBSTRATES OF COMPULSIVE CONSUMPTION: Based on the knowledge that some of the brain structures involved in drug rewards also participate during taste memory formation, we are evaluating the changes induced in behavior, brain structures and their chemical interactions, after chronic sugar consumption. This research seeks to understand the changes induced during long-term appetitive memory after chronic exposure to sugar and the effect during new taste learning and re-learning.
