Abstract:
Cerebellar Purkinje cells arborize unique dendrites that exhibit a planar, fan shape. The dendritic branches fill the space of their receptive field with little overlap. This dendritic arrangement is well-suited to form numerous synapses with the afferent parallel fibers of the cerebellar granule cells in a non-redundant manner. Purkinje cell dendritic arbor morphology is achieved by a combination of dynamic local branch growth behaviors, including elongation, branching, and retraction. Impacting these behaviors, the self-avoidance of each branch terminal is essential to form the non-overlapping dendritic configuration. This review outlines recent advances in our understanding of the cellular and molecular mechanisms of dendrite formation during cerebellar Purkinje cell development.

Avoidance Learning and Learned Helplessness
Avoidance learning occurs when an organism learns that a specific behavior can prevent an unpleasant outcome. For example, a student who receives a bad grade may start studying harder to avoid future poor grades. This behavior persists even when the negative outcome is no longer present. Avoidance learning is powerful because it maintains behavior in the absence of the...
