Abstract |
In this chapter, we discuss the modulation of pulvinar neuronal activity by arousal. In contrast to electrophysiological recordings in the early visual cortex, neuronal activity in the pulvinar is particularly sensitive to anesthesia. In the absence of sensory stimulation, pulvinar neurons can be characterized by spontaneous low-frequency rhythmic bursts of spiking activity. However, multisensory stimulation capable of arousing the animal from deeper anesthesia levels is able to reestablish the necessary neuronal dynamics and switch the pulvinar into an active state. Under these conditions, cortical slow-wave activity is substituted by a higher-frequency oscillatory pattern associated with arousal. Here, we describe two types of transitions in pulvinar activity pattern that can be observed when arousing the animal with multisensory stimulation. |
