Fig. 3. Spontaneous transitions between different activity patterns in single units
identified from multiunit recordings from CNSS. (A) SWA recording (i) in which
two tonically active Dahlgren cells become silent (ii,iv) and a quiescent cell
becomes tonically active (iii). (B) FWA recording (i) in which one cell
switches spontaneously from phasic to tonic activity (ii), one from tonic to
phasic activity (iii) and a third, quiescent, cell becomes bursting (iv).
