Developmental plasticity; Glutamate and acetylcholine receptors in visual cortex development

Research Description

We are interested in the development and plasticity of visual system. Our present research is concentrated on an early neonatal period in life, before the visual cortex attains its mature structure and function, that is, before lifelong connections among neurons are formed, and adult-type molecular signatures of different circuitries are established. During this period, the brain maintains a remarkable malleability to changes in the environment, such as lack of light, or lack of balanced stimulation through both eyes. By studying the molecules that are in function during this period, we aim to understand plasticity, that is what allows the brain to change, adapt, learn or resist to change in response to alterations in our environment. In particular, we are interested in the changing patterns of glutamate and GABA receptor localization in cells that receive monosynaptic input from developing thalamocortical cells, during, before and after the critical period for ocular dominance formation. We use the techniques, including tract-tracing and immunocytochemisty, to examine temporal sequence of neurotransmitter receptor localization at light and electron microscope resolutions.
