Pseudorabies virus (PRV), a neurovirulent α-herpesvirus, spreads between neurons at synaptic connections. PRV-infected neurons have been shown to exhibit functional deficits with the attenuated PRV152 Bartha strain negatively influencing neuronal functioning in in vitro model systems. However, the impact of this attenuated PRV152 Bartha strain on the native central nervous system has not been fully explored.

Motor behavior is generated by specific neural circuits. Those producing locomotion are located in the spinal cord, and their activation depends on descending inputs from the brain or on sensory inputs. In this study, we have used an in vitro brainstem-spinal cord preparation from adult zebrafish to localize a region where stimulation of descending inputs can induce sustained locomotor activity.

Neurons in the dorsal nucleus of the lateral lemniscus (DNLL) receive excitatory and inhibitory inputs from the superior olivary complex (SOC) and convey GABAergic inhibition to the contralateral DNLL and the inferior colliculi. Unlike the fast glycinergic inhibition in the SOC, this GABAergic inhibition outlasts auditory stimulation by tens of milliseconds. Two mechanisms have been postulated to explain this persistent inhibition.
