Vagus nerve stimulation parameters evoke differential neuronal responses in the locus coeruleus
Physiological Reports, 2023 Vagus nerve stimulation (VNS) is used to treat drug‐resistant epilepsy and depression, with additional applications under investigation. The noradrenergic center locus coeruleus (LC) is vital for VNS effects; however, the impact of varying stimulation ...

Neuroprotective effects of combined trimetazidine and progesterone on cerebral reperfusion injury
Current Research in Pharmacology and Drug Discovery, 2022 Cerebral ischemia-reperfusion injury induces multi-dimensional damage to neuronal cells through exacerbation of critical protective mechanisms.Targeting more than one mechanism simultaneously namely, inflammatory responses and metabolic energy ...

Self-Administration of Right Vagus Nerve Stimulation Activates Midbrain Dopaminergic Nuclei
Frontiers in Neuroscience, 2021 Background: Left cervical vagus nerve stimulation (l-VNS) is an FDA-approved treatment for neurological disorders including epilepsy, major depressive disorder, and stroke, and l-VNS is increasingly under investigation for a range of other neurological ...

Exploiting Separators for Guiding VNS [PDF]
Electronic Notes in Discrete Mathematics, 2012 This paper presents two extensions for DGVNS (Decomposition Guided VNS) method, that exploit both the graph of clusters and separators between these clusters, to efficiently guide the exploration of large neighborhoods in VNS. Experiments performed on challenging instances of the tagSNP selection problem show the appropriateness and the efficiency of ...

Elementary, Finite and Linear vN-Regular Cellular Automata [PDF]
Information and Computation 274, 2020, 2018 Let $G$ be a group and $A$ a set. A cellular automaton (CA) $\tau$ over $A^G$ is von Neumann regular (vN-regular) if there exists a CA $\sigma$ over $A^G$ such that $\tau \sigma\tau = \tau$, and in such case, $\sigma$ is called a generalised inverse of $\tau$. In this paper, we investigate vN-regularity of various kinds of CA. First, we establish that,

Increase in 20–50 Hz (gamma frequencies) power spectrum and synchronization after chronic vagal nerve stimulation [PDF]
, 2005 Objective: Though vagus nerve stimulation (VNS) is an important option in pharmacoresistant epilepsy, its mechanism of action remains unclear. The observation that VNS desynchronised the EEG activity in animals suggested that this mechanism could be ...
