Associative properties of structural plasticity based on firing rate homeostasis in recurrent neuronal networks

, 2018
Correlation-based Hebbian plasticity is thought to shape neuronal connectivity during development and learning, whereas homeostatic plasticity would stabilize network activity.

Synaptic Delays for Temporal Feature Detection in Dynamic Neuromorphic Processors [PDF]

Frontiers in Neuroscience; Neuromorphic Engineering (2020), 2019
Spiking neural networks implemented in dynamic neuromorphic processors are well suited for spatiotemporal feature detection and learning, for example in ultra low-power embedded intelligence and deep edge applications. Such pattern recognition networks naturally involve a combination of dynamic delay mechanisms and coincidence detection. Inspired by an

Loss of tumor necrosis factor (TNF)‐receptor 1 and TNF‐receptor 2 partially replicate effects of TNF deficiency on dendritic spines of granule cells in mouse dentate gyrus

Journal of Comparative Neurology, Volume 531, Issue 2, Page 281-293, February 2023., 2023
Hippocampal granule cells of adult mice lacking canonical TNF‐Rs were filled with Alexa568 and immunolabeled for Synaptopodin. Morphometric analysis of their spines revealed that TNF‐R mutants partially replicate changes previously reported for TNF‐deficient mice.

Increased ribosomal protein levels and protein synthesis in the striatal synaptosome of Shank3-overexpressing transgenic mice

Molecular Brain, 2021
The SH3 and multiple ankyrin repeat domains 3 (Shank3) protein is a core organizer of the macromolecular complex in excitatory postsynapses, and its defects cause numerous synaptopathies, including autism spectrum disorders.

Distinct forms of synaptic inhibition and neuromodulation regulate calretinin positive neuron excitability in the spinal cord dorsal horn [PDF]

, 2016
The dorsal horn (DH) of the spinal cord contains a heterogenous population of neurons that process incoming sensory signals before information ascends to the brain.

Organic Ferroelectric Synaptic Transistors for Neural Image Recognition Networks

Advanced Materials Interfaces, EarlyView.
All organic transistors, where both the dielectric and semiconducting layers are polymeric, are developed as electrical synaptic devices. Two copolymers of PVDF as the dielectric layer with large differences in their saturation polarizability and memory window are chosen.

Cortical synapses of the world's smallest mammal: An FIB/SEM study in the Etruscan shrew

Journal of Comparative Neurology, Volume 531, Issue 3, Page 390-414, February 2023., 2023
The present work provides a quantitative dataset of synapses from the Etruscan shrew (the smallest known terrestrial mammal). We have identified common and differing principles of synaptic organization compared to other mammalian species. Abstract The main aim of the present study was to determine if synapses from the exceptionally small brain of the ...

Bayesian inference of synaptic quantal parameters from correlated vesicle release

Frontiers in Computational Neuroscience, 2016
Synaptic transmission is both history-dependent and stochastic, resulting in varying responses to presentations of the same presynaptic stimulus. This complicates attempts to infer synaptic parameters and has led to the proposal of a number of different ...

The Absence of the Transient Receptor Potential Vanilloid 1 Directly Impacts on the Expression and Localization of the Endocannabinoid System in the Mouse Hippocampus

Frontiers in Neuroanatomy, 2021
The transient receptor potential vanilloid 1 (TRPV1) is a non-selective ligand-gated cation channel involved in synaptic transmission, plasticity, and brain pathology.
