Rotation Projects - Spring/Summer/Fall 2019 - 2020

There are two research areas in which rotation projects are available:

  1. Axonal regeneration.
    We have established a system in which to visualize in real time and in live, intact animals the process of axonal regeneration. Rotations in this area involve 1) the analysis of subcellular events (e.g. mitochondria dynamics) during axonal regeneration in wildtype (injured) but also in animals models for peripheral neuropathies; 2) the analysis of genes and genetic pathways critical for nerve regeneration.

  2. Simple Learning Behaviors 
    Rotations in this area involve behavioral testing of neuroactive drugs on their effects on learning/habituation. Rotatiosn projects also involve testing new optogenetic tools to visualize connectivity between identifed hindbrain neurons, and neural activity in these neurons.
    Techniques involved in this rotation include: high speed camera measurements, behavioral analysis using automated tracking software, drug applications, DNA extraction, imaging and molecular cloning techniques.
