Plasticity in neuronal responses is necessary for compensation following brain lesions and adaptation to new conditions and motor learning. In a previous study, we showed that compensatory changes in the vestibuloocular reflex (VOR) following unilateral vestibular loss were characterized by dynamic reweighting of inputs from vestibular and extravestibular modalities at the level of single neuro...

The purpose of this experiment is to confirm the effects of the descending pathway from the lateral vestibular nucleus (LVN) on rhythmic discharges induced by stimulation of the mesencephalic locomotor region (MLR) in the decerebrated cat. The experiments were performed on 18 adult cats (2.5-4.0 kg) of either sex. The rhythmic discharges produced by the MLR stimulation were recorded from hindli...

This study was conducted to assess the role of ionotropic glutamate receptors in the modulation of calcium dynamics on both sides of a vertebrate plastic synapse. Retrograde labeling of neuronal elements with high-affinity calcium-sensitive dyes was used in conjunction with confocal imaging techniques in an in vitro lamprey brain stem preparation. A prolonged calcium transient was measured both...
