Seizure activity in turtle brainstem induced by synaptic inhibition blockade. (A) Recordings of integrated motor output on roots of cranial nerves V, IX, and XII under control conditions (aCSF solution; left panels), and during synaptic inhibition blockade (picrotoxin, strychnine; right panels). Rhythmic activity on IX and XII roots was transformed into large synchronous bursts on all roots. (B) Recordings of integrated XII motor output along with 16 extracellular recordings from a pontine site rostral to cranial nerve root VI (see diagram at right) under control conditions (left panel) and during synaptic inhibition blockade (right panel). Synchronized bursts of action potentials were observed on all channels during synaptic inhibition blockade.
