Postsynaptic mechanisms for the induction of long-term potentiation and long-term depression of synaptic transmission in CA1 pyramidal neurons of the hippocampus [PDF]
arXiv, 2005 The studies described in this dissertation have attempted to address the cellular mechanisms of information storage by the brain. My work has focused primarily on the postsynaptic events that occur during and after induction of long-term potentiation (LTP) and long-term depression (LTD) at the Schaffer collateral-CA1 synapse of the hippocampus.

Role of Connexin 36 in Autoregulation of Oxytocin Neuronal Activity in Rat Supraoptic Nucleus
ASN Neuro, 2019 In the supraoptic nucleus (SON), the incidence of dye coupling among oxytocin (OT) neurons increases significantly in nursing mothers. However, the type(s) of connexin (Cx) involved is(are) unknown.

Frontiers in Cellular Neuroscience, 2013 Last evidences suggest that, in Alzheimer's disease (AD) early stage, Amyloid-β (Aβ) peptide induces an imbalance between excitatory and inhibitory neurotransmission systems resulting in the functional impairment of neural networks.

Synchronization-Induced Spike Termination in Networks of Bistable Neurons [PDF]
arXiv, 2018 We observe and study a self-organized phenomenon whereby the activity in a network of spiking neurons spontaneously terminates. We consider different types of populations, consisting of bistable model neurons connected electrically by gap junctions, or by either excitatory or inhibitory synapses, in a scale-free connection topology.

All-electric mimicking synaptic plasticity based on the noncollinear antiferromagnetic device [PDF]
arXivNeuromorphic computing, which seeks to replicate the brain's ability to process information, has garnered significant attention due to its potential to achieve brain-like computing efficiency and human cognitive intelligence. Spin-orbit torque (SOT) devices can be used to simulate artificial synapses with non-volatile, high-speed processing and ...

Contribute to balance, wire in accordance: Emergence of backpropagation from a simple, bio-plausible neuroplasticity rule [PDF]
arXivBackpropagation (BP) has been pivotal in advancing machine learning and remains essential in computational applications and comparative studies of biological and artificial neural networks. Despite its widespread use, the implementation of BP in the brain remains elusive, and its biological plausibility is often questioned due to inherent issues such ...

Synaptic sampling: A connection between PSP variability and uncertainty explains neurophysiological observations [PDF]
arXiv, 2015 When an action potential is transmitted to a postsynaptic neuron, a small change in the postsynaptic neuron's membrane potential occurs. These small changes, known as a postsynaptic potentials (PSPs), are highly variable, and current models assume that this variability is corrupting noise.
