Characterising the short-term habituation of event-related evoked potentials [PDF]

eneuro, 2017
AbstractFast-rising sensory events evoke a series of functionally heterogeneous event-related potentials (ERPs). Stimulus repetition at 1 Hz is known to induce a strong habituation of the largest ERP responses, the vertex waves, which are elicited by stimuli regardless of their modality7, provided that they are salient and behaviourally-relevant.

Locus Coeruleus Optogenetic Light Activation Induces Long-Term Potentiation of Perforant Path Population Spike Amplitude in Rat Dentate Gyrus

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,

Synaptic metaplasticity underlies tetanic potentiation in Lymnaea: a novel paradigm. [PDF]

PLoS ONE, 2013
We present a mathematical model that explains and interprets a novel form of short-term potentiation, which was found to be use-, but not time-dependent, in experiments done on Lymnaea neurons.

Short-term potentiation of off-responses in turtle horizontal cells [PDF]

Brain Research, 1991
Depolarizing responses to light off were studied in turtle horizontal cells using intracellular recording in the everted eyecup preparation. In many cells the off-response showed two components (fast and slow) which could overshoot beyond the steady-state dark level. The peak amplitudes of the fast and slow components increased with increasing duration

Synaptic Plasticity in the CA1 Area of the Hippocampus of Scrapie-Infected Mice

Neurobiology of Disease, 1998
Using conventionalin vitroextracellular field potential recordings we have investigated both short- and long-term synaptic plasticity in the hippocampal CA1 area of mice infected with ME7 scrapie.

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-

Learning-facilitated long-term depression and long-term potentiation at mossy fiber- CA3 synapses requires activation of ß-adrenergic receptors

Frontiers in Integrative Neuroscience, 2012
Learning-facilitated plasticity refers to hippocampal synaptic plasticity that is facilitated by novel spatial learning events. Both long-term potentiation (LTP) and long-term depression (LTD) are facilitated by novel hippocampus-dependent learning. This

Tunable Synaptic Plasticity in Crystallized Conjugated Polymer Nanowire Artificial Synapses

Advanced Intelligent Systems, 2020
In biological synapses, short‐term plasticity is important for computation and signal transmission, whereas long‐term plasticity is essential for memory formation.

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.
