Serotonin is a neuromodulator that implicated in awake-sleep cycle, motor behaviors, reward, motivation, and mood. Recent molecular tools for cell-type-specific activity recording manipulation with fine temporal spatial resolutions are providing unprecedentedly detailed data about serotonergic neuromodulation. These newly gained information show substantial differences the signaling effect of n...

Neurogenic bladder resulting from spinal cord injury and spina bifida has a profound impact on voiding function. This article reviews the current literature with regards to electrical stimulation for neurogenic bladder and the clinical outcomes associated with sacral neuromodulation, pudendal neuromodulation, posterior tibial nerve stimulation, and the Finetech-Brindley posterior/anterior stimu...

Neuromodulation may enhance the ability of sensory circuits to respond appropriately to widely variable environmental stimuli. The functional significance of neuromodulation will emerge from understanding the effects of modulators not just on single cells and synapses, but also on networks and the behavior of intact animals. With their relatively simple circuitry and large identifiable cells, i...

The results of neurophysiological research have indicated the important role of neuromodulation in behavior decisions during fighting between male crickets. To understand such a dynamic behavior generation mechanism, we attempt to construct a neuromodulation model of behavior selection for the fighting behavior of a cricket. In this paper, we propose a dynamic system model of neuromodulation wi...

Chronic subjective tinnitus is an auditory phantom phenomenon characterized by abnormal neuronal synchrony in the central auditory system. As shown computationally, acoustic coordinated reset (CR) neuromodulation causes a long-lasting desynchronization of pathological synchrony by downregulating abnormal synaptic connectivity. In a previous proof of concept study acoustic CR neuromodulation, em...

English Neuromodulation of spinal sensorimotor circuits improves motor control in animal models and humans with Spinal Cord Injury (SCI) and Parkinson disease. Stimulation parameters are tuned manually and remain constant during motor execution which is suboptimal to mediate maximum therapeutic effects. Here, I present a novel neuroprosthetic system that enabled adaptive changes of neuromodulat...

Neuromodulation is based on the revolutionary concept that paresthesia-inducing electrical stimulation could be analgesic. Its historical basis emanates from Melzack and Wall's gate control theory of pain proposed in 1965. Neuromodulation has given us ready access to the systems of pain modulation and helped mature the understanding of the pathophysiology of pain. Physiologic studies highlight ...

NEUROMODULATION FOR DEPRESSION: INSIGHTS GAINED FROM NEUROIMAGING AND COMPUTATIONAL MODELS Yagna Pathak, B.S., M.Eng. Marquette University, 2014 Major depressive disorder (MDD) is a public health concern worldwide, affecting a sixth of the American population. Neuromodulation therapies have been employed to treat severe cases of treatment resistant depression. These procedures attempt to modula...

Persistent cognitive disabilities represent the most troublesome consequences of acquired brain injury. Although these problems are widely recognized, few neuroprosthetic efforts have focused on developing therapeutic strategies aimed at improving general cognitive functions such as sustained attention, intention, working memory or awareness. If possible, effective modulation of these neuropsyc...
