Development and plasticity of the cortex
My students and I examine hormonal and environmental influences on neuronal structure in the cerebral cortex and other areas of the rat nervous system that involve cognition in the rat. Our current emphasis is on two time periods: early development and adolescence/puberty. We have found that adolescence is a time of considerable neuron reorganization including neuronal death, and the hormones secreted during puberty are influencing some of the changes. Current projects include the neural effects of endocrine disruptors (BPA, phthalates) on both neural development and adolescence and the effects of puberty on the neuroanatomical structure of the medial prefrontal cortex and associated behavior.
