Spike burst-pause dynamics of Purkinje cells regulate sensorimotor adaptation
Fig 8
Purkinje complex spike-pause frequency and VOR gain error during adaptation and post/pre adaptation.
The frequency of Purkinje complex spike-pauses (red squares) diminishes through VOR adaptation from 8–9 Hz to 2–3 Hz under a sinusoidal vestibular stimulus of ~1 Hz. After VOR adaptation, a direct random stimulation of CFs at 7 Hz during 30 min as in [50] impairs the VOR reflex. The evolution of the VOR gain error (Mean Absolute Error; black curve) during adaptation, post-adaptation, and artificial random stimulation of CFs.
