Our brains go through changes that are continuously renewing themselves as we experience the world. Research in my laboratory focuses on the multiple brain areas involved in processing episodic memories (spatio-temporal information) during navigation. We are interested in changes in the brain that occur as a result of practice or a learning experience. Multi-model aspects of memory, including visual, auditory, olfactory and proprioceptive aspects are being studied. Approaches include functional neuroimaging, neuroanatomy, neuropsychology, genetic and hormonal analyses with various populations that range from early development to senescence (patients with Epilepsy, Leukemia, Attention deficit hyperactivity disorder, Alzheimer's or Parkinson's disease). Applications are aimed at using multiple memory systems geared at rehabilitation techniques in patients with brain damage.

    2012 Society for Neuroscience Memory Systems Symposium

    Title: Independence and interaction of multiple memory systems

    Description: The purpose of this symposium is to integrate recent findings regarding the extent to which the medial temporal lobe system is independent of, or interactive with, other brain regions specialized for memory processing and storage. Brain regions that have been investigated extensively for their roles in memory include the medial temporal lobe, neostriatum, amygdala, and neocortex. The multiple memory systems hypothesis was supported initially by reports of dissociations among brain regions specialized for acquisition and storage of various types of information. While dissociations suggest independence among systems, there is also evidence that memory systems may be interactive during either memory formation or retrieval. Reports of interactions suggest that memory systems may be cooperative, competitive, or operate in temporal sequence. This symposium will bring together researchers who study multiple memory systems in human and non-human animal models at behavioral and physiological levels using genetic, electrophysiological, pharmacological, or fMRI methodologies. The goal will be to elucidate conditions under which brain regions operate independently or interactively during memory formation and retrieval. Moreover, for conditions in which memory systems are interactive, we will work toward an explanation of cooperation and competition.
