Striatonigral, pallidonigral, and nigrotectal synapses have different functional properties. The striatonigral synapse is facilitating (A), the pallidonigral synapse is depressing (B), and the nigrotectal synapse is sustainable or constant (C). A and B are adapted from Connelly et al. 2010 and C is adapted from Kaneda et al. 2008 with permission.
