25. The pharmacological blockade of medial forebrain bundle induces an acute pathological synchronization of the cortico–subthalamic nucleus–globus pallidus pathway
Pathological oscillations characterize the firing discharge of different basal ganglia (BG) stations in rat models of Parkinson's disease. Most recent literature focused on the prominence of the beta frequency band in awake rats. Yet, in 6-hydroxydopamine-lesioned animals, the firing discharge of the globus pallidus (GP) and the substantia nigra reticulata a

26. Design for an optical cw atom laser
A new type of optical cw atom laser design is proposed that should operate at high intensity and high coherence and possibly record low temperatures. It is based on an “optical-shepherd” technique, in which far-off-resonance blue-detuned swept sheet laser beams are used to make new types of high-density traps, atom waveguides, and other components for ac

27. Synaptic Noise and Physiological Coupling Generate High-Frequency Oscillations in a Hippocampal Computational Model
There is great interest in the role of coherent oscillations in the brain. In some cases, high-frequency oscillations (HFOs) are integral to normal brain function, whereas at other times they are implicated as markers of epileptic tissue. Mechanisms underlying HFO generation, especially in abnormal tissue, are not well understood. Using a physiological compu

28. Decreased upright cerebral blood flow and cerebral autoregulation in normocapnic postural tachycardia syndrome
Postural tachycardia syndrome (POTS), a chronic form of orthostatic intolerance, has signs and symptoms of lightheadedness, loss of vision, headache, fatigue, and neurocognitive deficits consistent with reductions in cerebrovascular perfusion. We hypothesized that young, normocapnic POTS patients exhibit abnormal cerebral autoregulation (CA) that results in
