Evidence is presented for modulation of the various components of neuronal Ca2+ currents by G-proteins and by gamma-aminobutyric acid B (GABAB) receptor activation. The mechanism of these interactions and the possible involvement of second messengers is discussed. The role of inhibition of Ca2+ channels in presynaptic inhibition of neurotransmitter release is examined.
