Signaling from the synapse to nucleus is mediated by the integration and propagation of both membrane potential changes (postsynaptic potentials) and intracellular second messenger cascades.

By investigating auditory hyperexcitability in a mouse model for hereditary deafness, this study identified a subpopulation of afferent neurons of the auditory nerve marked by Otogl expression. Despite their apparently normal hearing, Otogl+/− mice display poor activation of afferent neurons processing loud sounds and an elevation of the middle the ear

Gamma rhythms and beta rhythms have different synchronization properties [PDF]
Experimental and modeling efforts suggest that rhythms in the CA1 region of the hippocampus that are in the beta range (12-29 Hz) have a different dynamical structure than that of gamma (30-70 Hz).

Firing Cell: An Artificial Neuron with a Simulation of Long-Term-Potentiation-Related Memory [PDF]
We propose a computational model of neuron, called firing cell (FC), properties of which cover such phenomena as attenuation of receptors for external stimuli, delay and decay of postsynaptic potentials, modification of internal weights due to propagation of postsynaptic potentials through the dendrite, modification of properties of the analog memory ...

Mitochondria across the entire neuromuscular system have been comprehensively reconstructed at different developmental stages using 3D electron microscopy. Fundamental structural principles related to synaptic function are preserved across development, and these morphologies are adapted to ensure effective neural circuit function.

Identifying functional populations among the interneurons in laminae I-III of the spinal dorsal horn [PDF]
The spinal dorsal horn receives input from primary afferent axons, which terminate in a modality-specific fashion in different laminae. The incoming somatosensory information is processed through complex synaptic circuits involving excitatory and ...

A Molecularly Defined Medullary Network for Control of Respiratory Homeostasis
The dynamic interplay between central respiratory chemoreceptors and the respiratory central pattern generator is essential for maintaining stable respiratory rhythm and patterns, particularly during sleep. This study offers novel insights into the anatomical, molecular, and functional characteristics of a medullary network involving the nucleus ...

Aberrant excitatory rewiring of layer V pyramidal neurons early after neocortical trauma
Lesioned neuronal circuits form new functional connections after a traumatic brain injury (TBI). In humans and animal models, aberrant excitatory connections that form after TBI may contribute to the pathogenesis of post-traumatic epilepsy.

Accumulation of Dense Core Vesicles in Hippocampal Synapses Following Chronic Inactivity. [PDF]
The morphology and function of neuronal synapses are regulated by neural activity, as manifested in activity-dependent synapse maturation and various forms of synaptic plasticity.

This study examines the effects of Shank3 mutation on the mesoaccumbens pathway using a Shank3‐deficient rat model. The findings reveal altered social reward processing in these rats, accompanied by changes in dopaminergic and GABAergic neural activity within the ventral tegmental area (VTA) and dopamine release in the nucleus accumbense (NAc ...
