State-dependent complexity of the local field potential in the primary visual cortex [PDF]
arXiv, 2023 The local field potential (LFP) is as a measure of the combined activity of neurons within a region of brain tissue. While biophysical modeling schemes for LFP in cortical circuits are well established, there is a paramount lack of understanding regarding the LFP properties along the states assumed in cortical circuits over long periods.

Stabilizing membrane domains antagonizes n-alcohol anesthesia [PDF]
Biophysical Journal, Volume 111, Issue 3, 9 August 2016, Pages
537-545, 2016 Diverse molecules induce general anesthesia with potency strongly correlated both with their hydrophobicity and their effects on certain ion channels. We recently observed that several n-alcohol anesthetics inhibit heterogeneity in plasma membrane derived vesicles by lowering the critical temperature ($T_c$) for phase separation.

Nerves and Anesthesia: A physics perspective on medicine [PDF]
Anestezjologia i Ratownictwo 2014; 8: 252-263, 2014 We present a recent theory for nerve pulse propagation and anesthesia and argue that both nerve activity and the action of anesthetics can be understood on the basis of simple physical laws. It was found experimentally that biological membranes melt from a solid state to a liquid state just below physiological temperature. Such melting processes have a

Characterization of Large-Scale Functional Brain Networks During Ketamine-Medetomidine Anesthetic Induction [PDF]
arXiv, 2016 Several experiments provide evidence that specialized brain regions functionally interact and reveal that the brain processes and integrates information in a specific and structured manner. Networks can be applied to model brain functional activities, providing means to characterize and quantify this structured form of organization.

Automatic Ultrasound Image Segmentation of Supraclavicular Nerve Using Dilated U-Net Deep Learning Architecture [PDF]
arXiv, 2022 Automated object recognition in medical images can facilitate medical diagnosis and treatment. In this paper, we automatically segmented supraclavicular nerves in ultrasound images to assist in injecting peripheral nerve blocks. Nerve blocks are generally used for pain treatment after surgery, where ultrasound guidance is used to inject local ...

Structure and Dynamics of Brain Lobe's Functional Networks at the Onset of Anesthesia-Induced Loss of Consciousness [PDF]
arXiv, 2016 Anesthetic agents are neurotropic drugs capable of inducing significant alterations in the thalamocortical system, promoting a profound decrease in awareness and level of consciousness. There is experimental evidence that general anesthesia affects large-scale functional networks, leading to alterations in the brain's state.

Palatal ulceration: A local anesthetic complication
Indian Journal of Health Sciences and Biomedical Research KLEU, 2017 The hard palate is one of the common sites of local complications following administration of local anesthetics. The hard, unyielding palatal tissues coupled with either forceful or excessive administration of solution, induction of trauma, use of ...
