Rapid Recovery From Cortical Blindness Caused by an Old Cerebral Infarction
Frontiers in Neurology, 2020 When the primary visual cortex (V1) is damaged, cortical blindness results. However, visual information obtained from the superior colliculus (SC) or direct thalamic afferents to higher visual cortices produces unconscious visual functions called ...

Core-Shell Dual-Gate Nanowire Memory as a Synaptic Device for Neuromorphic Application
IEEE Journal of the Electron Devices Society, 2021 In this work, a synaptic device for neuromorphic system is proposed and designed to emulate the biological behaviors in the novel device structure of core-shell dual-gate (CSDG) nanowire flash memory.

Frontiers in Systems Neuroscience, 2019 Norepinephrine (NE) in dentate gyrus (DG) produces NE-dependent long-term potentiation (NE-LTP) of the perforant path-evoked potential population spike both in vitro and in vivo. Chemical activators infused near locus coeruleus (LC), the source of DG NE,

Bound states in the continuum (BIC) protected by self-sustained potential barriers in a flat band system [PDF]
Sci Rep 12, 11670 (2022), 2022 In this work, we investigate the bound states in the continuum (BIC) of a one-dimensional spin-1 flat band system. It is found that, when the potential is sufficiently strong, there exists an effective attractive potential well surrounded by infinitely high self-sustained barriers.

Numerical modelling of plasticity induced by transcranial magnetic stimulation [PDF]
, 2013 We use neural field theory and spike-timing dependent plasticity to make a simple but biophysically reasonable model of long-term plasticity changes in the cortex due to transcranial magnetic stimulation (TMS).

Long-term potentiation in frontal cortex: Role of NMDA-modulated polysynaptic excitatory pathways [PDF]
, 1989 The present study examined the role of N-methyl-D-aspartic acid (NMDA) receptors in synaptic plasticity in regular-spiking cells of rat frontal cortex. Intracortical stimulation, at levels subthreshold for elicitation of action potentials, evoked a late ...

SynaptoPAC, an optogenetic tool for induction of presynaptic plasticity [PDF]
, 2020 Optogenetic manipulations have transformed neuroscience in recent years. While sophisticated tools now exist for controlling the firing patterns of neurons, it remains challenging to optogenetically define the plasticity state of individual synapses.

Synaptic Alterations in Mouse Models for Alzheimer Disease—A Special Focus on N-Truncated Abeta 4-42
Molecules, 2018 This commentary reviews the role of the Alzheimer amyloid peptide Aβ on basal synaptic transmission, synaptic short-term plasticity, as well as short- and long-term potentiation in transgenic mice, with a special focus on N-terminal truncated Aβ4-42. Aβ4-

Activation of Astrocytes in the Persistence of Post-hypoxic Respiratory Augmentation
Frontiers in Physiology, 2021 Acute hypoxia increases ventilation. After cessation of hypoxia loading, ventilation decreases but remains above the pre-exposure baseline level for a time.

Optimized Periodic Coulomb Potential in Two Dimension [PDF]
J. Comput. Phys. 206, 111 (2005), 2004 The 1/r Coulomb potential is calculated for a two dimensional system with periodic boundary conditions. Using polynomial splines in real space and a summation in reciprocal space we obtain numerically optimized potentials which allow us efficient calculations of any periodic (long-ranged) potential up to high precision.
