Vagus nerve stimulation in the sensory cortex of rats.

rats

Link – Vagus nerve stimulation (VNS)-induced layer-specific modulation of evoked responses in the sensory cortex of rats. Abstract Neuromodulation achieved by vagus nerve stimulation (VNS) induces various neuropsychiatric effects whose underlying mechanisms of action remain poorly understood. Innervation of neuromodulators and a microcircuit structure in the cerebral cortex informed the hypothesis that VNS exerts layer-specific […]

Vagus nerve stimulation intensities produce motor cortex reorganization

rats

Link – A limited range of vagus nerve stimulation intensities produce motor cortex reorganization when delivered during training. Abstract Pairing vagus nerve stimulation (VNS) with rehabilitation has emerged as a potential strategy to improve recovery after neurological injury, an effect ascribed to VNS-dependent enhancement of synaptic plasticity. Previous studies demonstrate that pairing VNS with forelimb […]

Rat vagus nerve stimulation parameters

Link – Identification of vagus nerve stimulation parameters affecting rat hippocampal electrophysiology without temperature effects. Abstract BACKGROUND: Recent experiments in rats have demonstrated significant effects of VNS on hippocampal excitability but were partially attributed to hypothermia, induced by the applied VNS parameters. OBJECTIVE: To allow meaningful preclinical research on the mechanisms of VNS and translation […]

α7nAchR mediates taVNS by enhancing axonal plasticity.

Link – α7nAchR mediates transcutaneous auricular vagus nerve stimulation-induced neuroprotection in a rat model of ischemic stroke by enhancing axonal plasticity. Abstract Axonal plasticity is important for neurofunctional recovery after stroke. This study aimed to explore the role of transcutaneous auricular vagus nerve stimulation (ta-VNS) on axonal plasticity and its underlying association with the α7 […]

tDCS exerts neuroprotective effect in rat brain after stroke.

Link – Cathodal tDCS exerts neuroprotective effect in rat brain after acute ischemic stroke. Abstract BACKGROUND: Transcranial direct current stimulation (tDCS) is a non-invasive brain modulation technique that has been proved to exert beneficial effects in the acute phase of stroke. To explore the underlying mechanism, we investigated the neuroprotective effects of cathodal tDCS on […]

Rodent EEG: Expanding the Spectrum of Analysis.

Link – Rodent EEG: Expanding the Spectrum of Analysis. Abstract In epilepsy research, the analysis of rodent electroencephalogram (EEG) has been performed by many laboratories with a variety of techniques. However, the acquisition and basic analysis of rodent EEG have only recently been standardized. Since a number of software platforms and increased computational power have […]

Vagus nerve stimulation parameters on gastric motility

Link – Acute effects of vagus nerve stimulation parameters on gastric motility assessed with magnetic resonance imaging. Abstract BACKGROUND: Vagus nerve stimulation (VNS) is an emerging bioelectronic therapy for regulating food intake and controlling gastric motility. However, the effects of different VNS parameters and polarity on postprandial gastric motility remain incompletely characterized. METHODS: In anesthetized […]

tDCS accelerates neural functional recovery in Rats

Link – Transcranial direct current stimulation treated bymultileadbrain reflex instrument accelerates neural functional recovery in a rat model of stroke. Abstract Clinical research suggests that transcranial direct current stimulation(tDCS) at bilateral supraorbital foramen and inferior orbital rim and nose intersectionsmay facilitate rehabilitation after stroke.However,the underlying neurobiological mechanisms of tDCSremain poorly understood, impeding its clinical application.

Link – Memory and Cognition-Related Neuroplasticity Enhancement by Transcranial Direct Current Stimulation in Rodents: A Systematic Review. Abstract Brain stimulation techniques, including transcranial direct current stimulation (tDCS), were identified as promising therapeutic tools to modulate synaptic plasticity abnormalities and minimize memory and learning deficits in many neuropsychiatric diseases. Here, we revised the effect of tDCS […]

Predicting neural spiking activity from oscillatory phase.

Link – A flexible likelihood approach for predicting neural spiking activity from oscillatory phase. Abstract BACKGROUND: The synchronous ionic currents that give rise to neural oscillations have complex influences on neuronal spiking activity that are challenging to characterize. NEW METHOD: Here we present a method to estimate probabilistic relationships between neural spiking activity and the […]
