Dr. Bachevalier received a Doctorate Degree in Psychophysiology from the University of Paris in 1975 and a Ph. D. in Clinical Sciences from the University of Montreal in 1981. She was a Visiting Scientist at the National Institute of Mental Health in Bethesda (MD) until 1991 and then took a position of Professor in Neurobiology and Anatomy at the University of Texas-Houston. She joined the Emory faculty in Summer, 2004.

  1. Research Program: Our laboratory investigates the neural substrates underlying the development of learning and memory functions, and the regulation of socioemotional behaviors in nonhuman primates. An important facet of our research program has been to relate basic findings in nonhuman primates to normal development of cognitive functions in children and to abnormal human behavior, such as autism, schizophrenia, and anxiety disorders.  Our studies use a combination of newly designed behavioral tasks to test episodic-like memory processes, decision-making abilities and emotional regulation in infant and adult monkeys as well as observations of social skills in semi-naturalistic environment, selective MRI-guided neurotoxic lesions and neurochemical deactivations, and neuroimaging techniques (structural MRI, Diffusion Tensor Imaging, and Spectroscopy) and neuroanatomical procedures to assess brain reorganization following neonatal brain lesions.

  2. Current studies:
  • The development of medial temporal lobe functions: This project investigates the role of different medial temporal structures and their interactions with the prefrontal cortex in episodic-like memory processes in the adult monkeys and assesses how the maturational time course of these brain areas map onto the development of these memory processes from infancy through adulthood. 
  • Safety signal learning in monkeys: cortical regulation and its development: This collaborative project with Dr. Michael Davis (YNPRC) is an attempt to modify our existing fear inhibition paradigm to permit its use longitudinally, first to investigate (pre- and post-surgery) which specific orbital frontal sectors are involved in the acquisition and expression of conditioned inhibition (safety signal learning) in male and female adult monkeys and second follow longitudinally when orbital frontal regulation of conditioned inhibition emerged in primates of both sexes. 
  • Amygdala: sex differences in behavior, cognition and neuroendocrine development: This collaborative with Drs Kim Wallen and Mar Sanchez  investigates social, emotional, cognitive and neuroendocrine consequences of neonatal and post-pubertal amygdalectomy in male and female rhesus monkeys living in semi-natural complex social groups.
  • Hippocampal-Prefrontal Control of Working Memory: Inactivation and PET in Monkeys:  This study, headed by Dr. Maria Alvarado, combines pharmacological inactivation, PET imaging and neuroanatomical tracers to directly assess whether hippocampal modulation of dorsolateral PFC function occurs via the meso-limbic dopamine system (a circuit including the nucleus accumbens, ventral pallidum and ventral tegmental area (VTA)) in nonhuman primates
