Research titled "Encoding of self-initiated actions in axon terminals of the mesocortical pathway" reported in Neurophotonics dives into this mystery by investigating how mice time their actions ...

which transport materials from the cell body to the axon terminals at the synapse. (D) The growth cone contains dendritic actin filament networks and parallel actin filament filopodia.

Carnegie Mellon University neuroscientists have discovered connections between the globus pallidus and a rarely explored area of the brain.
