Abstract

Objective: Freezing of gait (FOG) is among the most common and disabling symptoms of Parkinson's disease (PD). While the efficacy of deep brain stimulation (DBS) of the subthalamic nucleus (STN) has been proven in large randomized, controlled trials, its effect on FOG is still insufficiently understood.

34. Coherence properties of a semiconmductor laser with feedback from a distant reflector: experiment and theory

Author

Hamel, W. A., Exter, M. P. van, and Woerdman, J. P.

Subjects
Semiconductor lasers -- Analysis, Business, Computers, Electronics, Electronics and electrical industries
Abstract

The spectral characteristics of a semiconductor laser subjected to optical feedback is studied. A mirror, placed at an external cavity exceeding the coherence length of the emitted laser beam, was used as the feedback medium. The intensity of the feedback was varied and its reactions were evaluated. The beam's coherent properties were then investigated using a Michelson interferometer and the results were compared with those obtained through an analytical method. A strong agreement between the results was noted.

Abstract

The effects of relaxation oscillations on the optical spectrum of a single-mode semiconductor laser is studied. The laser's broad weak sidebands were subjected to relaxation oscillations and investigated using heterodyne detection technique. A theoretical mathematical approach was then formulated to validate the reliability of the heterodyne experiment. Results from both methods indicate that the damping of the relaxation oscillations was controlled by the system's high output power gains saturation.

Abstract

Contains fulltext : 157474.pdf (Publisher’s version ) (Open Access) In contrast to its well-established role in alleviating skeleto-motor symptoms in Parkinson's disease, little is known about the impact of deep brain stimulation (DBS) of the subthalamic nucleus (STN) on oculomotor control and attention. Eye-tracking data of 17 patients with left-hemibody symptom onset was compared with 17 age-matched control subjects. Free-viewing of natural images was assessed without stimulation as baseline and during bilateral DBS. To examine the involvement of ventral STN territories in oculomotion and spatial attention, we employed unilateral stimulation via the left and right ventralmost contacts respectively. When DBS was off, patients showed shorter saccades and a rightward viewing bias compared with controls. Bilateral stimulation in therapeutic settings improved saccadic hypometria but not the visuospatial bias. At a group level, unilateral ventral stimulation yielded no consistent effects. However, the evaluation of electrode position within normalized MNI coordinate space revealed that the extent of early exploration bias correlated with the precise stimulation site within the left subthalamic area. These results suggest that oculomotor impairments "but not higher-level exploration patterns" are effectively ameliorable by DBS in therapeutic settings. Our findings highlight the relevance of the STN topography in selecting contacts for chronic stimulation especially upon appearance of visuospatial attention deficits. 13 p.

Abstract

Cortex-basal ganglia circuits participate in motor timing and temporal perception, and are important for the dynamic configuration of sensorimotor networks in response to exogenous demands. In Parkinson's disease (PD) patients, rhythmic auditory stimulation (RAS) induces motor performance benefits. Hitherto, little is known concerning contributions of the basal ganglia to sensory facilitation and cortical responses to RAS in PD. Therefore, we conducted an EEG study in 12 PD patients before and after surgery for subthalamic nucleus deep brain stimulation (STN-DBS) and in 12 age-matched controls. Here we investigated the effects of levodopa and STN-DBS on resting-state EEG and on the cortical-response profile to slow and fast RAS in a passive-listening paradigm focusing on beta-band oscillations, which are important for auditory–motor coupling. The beta-modulation profile to RAS in healthy participants was characterized by local peaks preceding and following auditory stimuli. In PD patients RAS failed to induce pre-stimulus beta increases. The absence of pre-stimulus beta-band modulation may contribute to impaired rhythm perception in PD. Moreover, post-stimulus beta-band responses were highly abnormal during fast RAS in PD patients. Treatment with levodopa and STN-DBS reinstated a post-stimulus beta-modulation profile similar to controls, while STN-DBS reduced beta-band power in the resting-state. The treatment-sensitivity of beta oscillations suggests that STN-DBS may specifically improve timekeeping functions of cortical beta oscillations during fast auditory pacing.
