Torpedoes, swellings of the proximal Purkinje cell axon, are thought to represent a cellular response to injury . They may occur in a variety of cerebellar disorders . Most recently, their numbers were noted to be six-times higher in essential tremor (ET) than control brains . Torpedoes are also often viewed as a cumulative phenomenon associated with advanced aging [3,4], yet there are surprisingly few supporting data. We quantified torpedoes in normal human cerebella spanning a considerable age range to assess whether torpedoes are a cumulative phenomenon of aging. These data help place the relative abundance of torpedoes in ET in context.
