Subcortical Oscillations in Human Sleep Dysregulation

Sleep problems are common in the United States (US) adult population (>50 million), and have a negative impact on quality of life, productivity, and healthcare. A major obstacle to understanding how the brain is involved in human sleep disorders has been the lack of recordings of human brain function, from inside the brain, during the known sleep states.


Sleep is necessary for life; critically important to the regulation of body and brain function. Sleep problems are common in the U.S. adult population (>50 million), and have a negative impact on quality of life, productivity, and healthcare. A major obstacle to understanding how the brain is involved in human sleep disorders has been the lack of recordings of brain function, from inside the brain, during the known sleep states; non-rapid eye movement (NREM) and rapid eye movement (REM). It is very common for patients with Parkinson's disease (PD) to also have sleep disorders, such as insomnia, restless-leg-syndrome and REM-behavior disorder. One treatment for PD patients is deep brain stimulation (DBS) of the subthalamic nucleus (STN-DBS). Despite evidence showing that STN-DBS improves several aspects of sleep behavior in PD subjects, few studies have examined the relationship between brain activity and sleep regulation in human subjects. In this proposal, the investigators will examine sleep in humans by recording brain activity from STN of PD patients who have undergone DBS surgery. The investigators will also test the hypothesis that STN contributes to both the regulation and disruption of normal sleep behavior.

Proteins associated with sporadic or familial cases of PARKINSON DISEASE.

Dyssomnias (i.e., insomnias or hypersomnias) associated with dysfunction of internal sleep mechanisms or secondary to a sleep-related medical disorder (e.g., sleep apnea, post-traumatic sleep disorders, etc.). (From Thorpy, Sleep Disorders Medicine, 1994, p187)

A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)

Movements or behaviors associated with sleep, sleep stages, or partial arousals from sleep that may impair sleep maintenance. Parasomnias are generally divided into four groups: arousal disorders, sleep-wake transition disorders, parasomnias of REM sleep, and nonspecific parasomnias. (From Thorpy, Sleep Disorders Medicine, 1994, p191)
