Murray et al. Image (IMAGE) The Zuckerman Institute at Columbia University Caption This is an image of a mouse brain that has received an injection of an adeno-associated virus (green) into the LVN. The virus makes a synaptic protein that is tagged with green fluorescent protein, this allows us to follow the projections coming from the LVN through the brain and spinal cord.
