Pairing Sound with Vagus Nerve Stimulation Modulates Cortical Synchrony and Phase Coherence in Tinnitus: An Exploratory Retrospective Study
Recent research has shown that vagus nerve stimulation (VNS) paired with tones or with rehabilitative training can help patients to achieve reductions in tinnitus perception or to expedite motor rehabilitation after suffering ...
Effects of Vagus Nerve Stimulation on Extinction of Conditioned Fear and Post-Traumatic Stress Disorder Symptoms in Rats
Exposure-based therapies help patients with post-traumatic stress disorder (PTSD) to extinguish conditioned fear of trauma reminders. However, controlled laboratory studies indicate that PTSD patients do not extinguish ...
Norepinephrine and Serotonin are Required for Vagus Nerve Stimulation Directed Cortical Plasticity
(Academic Press Inc., 2019-06-07)
Vagus nerve stimulation (VNS) paired with forelimb training drives robust, specific reorganization of movement representations in the motor cortex. This effect is hypothesized to be mediated by VNS-dependent engagement of ...
Cortical Map Plasticity as a Function of Vagus Nerve Stimulation Rate
Background: Repeatedly pairing a brief train of vagus nerve stimulation (VNS) with an external event can reorganize the sensory or motor cortex. A 30 Hz train of sixteen VNS pulses paired with a tone significantly increases ...
Vagus Nerve Stimulation Rate and Duration Determine Whether Sensory Pairing Produces Neural Plasticity
Repeatedly pairing a brief train of vagus nerve stimulation (VNS) with an auditory stimulus drives reorganization of primary auditory cortex (A1), and the magnitude of this VNS-dependent plasticity is dependent on the ...
Closed-Loop Neuromodulation Restores Network Connectivity and Motor Control After Spinal Cord Injury
Recovery from serious neurological injury requires substantial rewiring of neural circuits. Precisely-timed electrical stimulation could be used to restore corrective feedback mechanisms and promote adaptive plasticity ...
Vagus Nerve Stimulation Promotes Generalization of Conditioned Fear Extinction and Reduces Anxiety in Rats
(Elsevier Science Inc, 2018-09-21)
Background: Exposure-based therapies are used to treat a variety of trauma- and anxiety-related disorders by generating successful extinction following cue exposure during treatment. The development of adjuvant strategies ...
