The basal ganglia (BG) are involved in numerous neurobiological processes that operate on the basis of wakefulness, including motor function, learning, emotion and addictive behaviors. We hypothesized that the BG might play an important role in the regulation of wakefulness. To test this prediction, we made cell body-specific lesions in the striatum and globus pallidus (GP) using ibotenic acid. We found that rats with striatal (caudoputamen) lesions exhibited a 14.95% reduction in wakefulness and robust fragmentation of sleep–wake behavior, i.e. an increased number of state transitions and loss of ultra-long wake bouts (> 120 min). These lesions also resulted in a reduction in the diurnal variation of sleep–wakefulness. On the other hand, lesions of the accumbens core resulted in a 26.72% increase in wakefulness and a reduction in non-rapid eye movement (NREM) sleep bout duration. In addition, rats with accumbens core lesions exhibited excessive digging and scratching. GP lesions also produced a robust increase in wakefulness (45.52%), and frequent sleep–wake transitions and a concomitant decrease in NREM sleep bout duration. Lesions of the subthalamic nucleus or the substantia nigra reticular nucleus produced only minor changes in the amount of sleep–wakefulness and did not alter sleep architecture. Finally, power spectral analysis revealed that lesions of the striatum, accumbens and GP all resulted in a shifting of fast theta power to slow delta power, i.e. a slowing of the cortical electroencephalogram. Collectively, our results suggest that the BG, via a cortico-striato-pallidal loop, are important neural circuitry regulating sleep–wake behaviors and cortical activation.
