Understanding the Molecular and Cell Biological Mechanisms of Electrical Synapse Formation

open access: yesFrontiers in Neuroanatomy, 2020
In this review article, we will describe the recent advances made towards understanding the molecular and cell biological mechanisms of electrical synapse formation. New evidence indicates that electrical synapses, which are gap junctions between neurons,

The symphony of smell: a role for electrical synapses [PDF]

open access: yesThe Journal of Physiology, 2017
Rhythmic electrical activities are ubiquitous in the brain and inextricably tied to neural circuit operations. Macroscopic oscillations in extracellular voltage – the local field potential (LFP) – are commonly observed and span a wide frequency spectrum (∼1.5 – 100 Hz). This article is protected by copyright.

Small Extracellular Vesicles from Neural Cells: Physiological and Pathological Roles, and Potential in Neurodegenerative Therapy

open access: yesAdvanced Healthcare Materials, EarlyView.
Neural cell–derived small extracellular vesicles (sEVs) are emerging as pivotal mediators in neurodegenerative diseases, exerting both pathogenic and therapeutic functions. This review synthesizes current evidence on how sEVs from distinct neural cell types regulate neurodegeneration, neuroprotection, biomarker discovery, and targeted drug delivery ...

A Population of Projection Neurons that Inhibits the Lateral Horn but Excites the Antennal Lobe through Chemical Synapses in Drosophila

open access: yesFrontiers in Neural Circuits, 2017
In the insect olfactory system, odor information is transferred from the antennal lobe (AL) to higher brain areas by projection neurons (PNs) in multiple AL tracts (ALTs).

The components of an electrical synapse as revealed by expansion microscopy of a single synaptic contact

open access: yeseLife
Most nervous systems combine both transmitter-mediated and direct cell–cell communication, known as ‘chemical’ and ‘electrical’ synapses, respectively. Chemical synapses can be identified by their multiple structural components.
