Characterization of NMDAR-independent learning in the hippocampus.

Frontiers in Behavioral Neuroscience, 2011
It is currently thought that memory formation requires the activation of NMDA receptors (NMDARs) in the hippocampus. However, recent studies indicate that these receptors are not necessary for all forms of learning. The current experiments examine this

Models of metaplasticity: a review of concepts

Frontiers in Computational Neuroscience, 2015
Part of hippocampal or cortical plasticity is characterized by synaptic modifications as a function of the joint activity of the pre- and postsynaptic neurons.

Adding a Second iTBS Block in 15 or 60 Min Time Interval Does Not Increase iTBS Effects on Motor Cortex Excitability and the Responder Rates

Brain Sciences, 2022
The use of metaplasticity-based intermittent theta-burst stimulation (iTBS) protocols including several stimulation blocks could be a possible approach to increasing stimulation effectiveness.

Programmable Synaptic Metaplasticity and below Femtojoule Spiking Energy Realized in Graphene-Based Neuromorphic Memristor.

ACS Applied Materials and Interfaces, 2018
Memristors with rich interior dynamics of ion migration are promising for mimicking various biological synaptic functions in neuromorphic hardware systems. A graphene-based memristor shows an extremely low energy consumption of less than a femtojoule per

Intra- and Inter-Regional Priming of Ipsilateral Human Primary Motor Cortex With Continuous Theta Burst Stimulation Does Not Induce Consistent Neuroplastic Effects

Frontiers in Human Neuroscience, 2018
Human responses to non-invasive brain stimulation (NIBS) techniques can be highly variable. Recently, priming protocols involving a conditioning round of NIBS applied to a target brain region prior to the application of a test protocol have shown promise

The evolution of sensitive periods beyond early ontogeny: Bridging theory and data

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Sensitive periods, in which experiences have a large impact on phenotypic development, are most common early in ontogeny. Yet, they may also occur at later ontogenetic stages, such as adolescence.

TriRE: A Multi-Mechanism Learning Paradigm for Continual Knowledge Retention and Promotion [PDF]

arXiv, 2023
Continual learning (CL) has remained a persistent challenge for deep neural networks due to catastrophic forgetting (CF) of previously learned tasks. Several techniques such as weight regularization, experience rehearsal, and parameter isolation have been proposed to alleviate CF.

Updating perspectives on spinal cord function: motor coordination, timing, relational processing, and memory below the brain

Frontiers in Systems Neuroscience
Those studying neural systems within the brain have historically assumed that lower-level processes in the spinal cord act in a mechanical manner, to relay afferent signals and execute motor commands.

Frequency-dependent cannabinoid receptor-independent modulation of glycine receptors by endocannabinoid 2-AG

Frontiers in Molecular Neuroscience, 2011
Endocannabinoids are known as retrograde messengers, being released from the postsynaptic neuron and acting on specific presynaptic G-protein-coupled cannabinoid (CB) receptors to decrease neurotransmitter release.
