Explanatory problems in the philosophy of neuroscience are not weil capture
d by the division between the radical and the trivial neuron doctrines. The
actual problem is, instead, whether mechanistic biological explanations ac
ross different levels of description can be extended to account for psychol
ogical phenomena. According to cognitive neuroscience, some neural levels o
f description at least are essential for the explanation of psychological p
henomena, whereas, in traditional cognitive science, psychological explanat
ions are completely independent of the neural levels of description. The ch
allenge for cognitive neuroscience is to discover the levels of description
appropriate for the neural explanation of psychological phenomena.
