Bushy cells are two types of second order neuron found in the anterior part of the ventral cochlear nucleus, the AVCN.
They can be globular or spherical giving outputs to different parts of the superior olivary complex.
Projections from the globular bushy cells extend to the superior olive on both sides of the brainstem where they give input to the bipolar neurons.
[1] Projections from the spherical bushy cells give excitatory input to the lateral and medial parts of the superior olive (the LSO and MSO).
