Neural synchronization can be modulated by task constraints, such as attention, and is thought to play a role in feature binding, neuronal communication, and motor coordination. Neuronal oscillations became a hot topic in neuroscience in the 1990s when the studies of the visual system of the brain by Gray, Singer and others appeared to support the neural binding hypothesis. According to this idea, synchronous oscillations in neuronal ensembles bind neurons representin… ra skoleWebThe Real (Nonlinear) Simple Pendulum. When the angular displacement amplitude of the pendulum is large enough that the small angle approximation no longer holds, then the equation of motion must remain in its nonlinear form $$ \frac{d^2\theta}{dt^2} + \frac{g}{L}\sin\theta = 0 $$ This differential equation does not have a closed form … dr polacek cranston ri

WebJan 25, 2024 · Locomotion has long been associated with rhythmic oscillations in the rat hippocampus. Running speed and acceleration affect the spectral density at the theta (6-10 Hz) and gamma (30-150 Hz) bands and the rhythmic entrainment of neuronal activity. However, less is known about other oscillatory rhythms. Recent studies have shown that … Weboscillations are assumed to be in the theta band (7–11 Hz in adult freely-moving rats), and the difference between them is assumed to be due to a change in frequency of one of the oscilla-tors caused by depolarization by a velocity-dependent synaptic input i.e., it operates as a velocity-controlled oscillator.
