Outline of Research at the Start

This study will explore how the brain's smell center, the olfactory bulb, uses different neuron types to process scents. We'll employ precise light-based techniques to stimulate these neurons and observe the effects on behavior. This approach will test if two types of output neurons, known as mitral and tufted cells, encode olfactory signals using different temporal patterns of activity. This will help us figure out how the brain distinguishes between various aspects of smells using different mechanisms. It's an important step toward grasping the complex ways our brain makes sense of smells.
