Ethanol enhances neurosteroidogenesis in hippocampal pyramidal neurons by paradoxical NMDA receptor activation [PDF]

, 2011
Using an antibody against 5α-reduced neurosteroids, predominantly allopregnanolone, we found that immunostaining in the CA1 region of rat hippocampal slices was confined to pyramidal neurons.

On the Biological Plausibility of Artificial Metaplasticity [PDF]

, 2011
The training algorithm studied in this paper is inspired by the biological metaplasticity property of neurons. Tested on different multidisciplinary applications, it achieves a more efficient training and improves Artificial Neural Network Performance ...

Plasticity in the Prefrontal Cortex of Adult Rats

Frontiers in Cellular Neuroscience, 2015
We review the plastic changes of the prefrontal cortex of the rat in response to a wide range of experiences including sensory and motor experience, gonadal hormones, psychoactive drugs, learning tasks, stress, social experience, metaplastic experiences,

Bayesian Metaplasticity from Synaptic Uncertainty [PDF]

arXiv, 2023
Catastrophic forgetting remains a challenge for neural networks, especially in lifelong learning scenarios. In this study, we introduce MEtaplasticity from Synaptic Uncertainty (MESU), inspired by metaplasticity and Bayesian inference principles.

Promoting neurological recovery of function via metaplasticity [PDF]

, 2010
The modification of synapses by neural activity has been proposed to be the substrate for experience-dependent brain development, learning, and recovery of visual function after brain injury.

The computational power of astrocyte mediated synaptic plasticity

Frontiers in Computational Neuroscience, 2012
Research in the last two decades has made clear that astrocytes play a crucial role in the brain beyond their functions in energy metabolism and homeostasis.

Power-law forgetting in synapses with metaplasticity [PDF]

J. Stat. Mech. (2011) P09025, 2011
The idea of using metaplastic synapses to incorporate the separate storage of long- and short-term memories via an array of hidden states was put forward in the cascade model of Fusi et al. In this paper, we devise and investigate two models of a metaplastic synapse based on these general principles.

Neural mechanisms of social learning in the female mouse [PDF]

, 2017
Social interactions are often powerful drivers of learning. In female mice, mating creates a long-lasting sensory memory for the pheromones of the stud male that alters neuroendocrine responses to his chemosignals for many weeks.
