The implication of a diversity of non-neuronal cells in disorders affecting brain networks

Frontiers in Cellular Neuroscience, 2022
In the central nervous system (CNS) neurons are classically considered the functional unit of the brain. Analysis of the physical connections and co-activation of neurons, referred to as structural and functional connectivity, respectively, is a metric ...

Rapid, learning-induced inhibitory synaptogenesis in murine barrel field [PDF]

, 2010
The structure of neurons changes during development and in response to injury or alteration in sensory experience. Changes occur in the number, shape, and dimensions of dendritic spines together with their synapses. However, precise data on these changes

Electrochemistry at the Synapse [PDF]

Annual Review of Analytical Chemistry, 2019
Electrochemical measurements of neurotransmitters provide insight into the dynamics of neurotransmission. In this review, we describe the development of electrochemical measurements of neurotransmitters and how they started with extrasynaptic measurements but now are pushing toward synaptic measurements.

Pathological and Synaptic Morphological Changes of the Olfactory Bulb in APP/PS1 Model Mice at Different Ages and the Intervention Effect of Memantine

Shiyan dongwu yu bijiao yixue, 2022
Objective To compare and explore the histopathological and ultrastructural characteristics of the olfactory bulb in 6- and 12-month-old APP/PS1 double-transgenic mice and their spatial learning and memory ability, as well as the effects of memantine ...

Autophagy at the synapse [PDF]

Neuroscience Letters, 2019
As the sites of communication between neurons, synapses depend upon precisely regulated protein-protein interactions to support neurotransmitter release and reception. Moreover, neuronal synapses typically exist great distances (i.e. up to meters) away from cell bodies, which are the sources of new proteins and the major sites of protein degradation ...

Face classification using electronic synapses

Nature Communications, 2017
Conventional hardware platforms consume huge amount of energy for cognitive learning due to the data movement between the processor and the off-chip memory.

Connexin36 Expression in the Mammalian Retina: A Multiple-Species Comparison

Frontiers in Cellular Neuroscience, 2017
Much knowledge about interconnection of human retinal neurons is inferred from results on animal models. Likewise, there is a lack of information on human retinal electrical synapses/gap junctions (GJ).

Rostral and caudal basolateral amygdala engage distinct circuits in the prelimbic and infralimbic prefrontal cortex

eLife, 2022
Connections from the basolateral amygdala (BLA) to medial prefrontal cortex (PFC) regulate memory and emotion and become disrupted in neuropsychiatric disorders.

Modeling Maintenance of Long-Term Potentiation in Clustered Synapses, Long-Term Memory Without Bistability [PDF]

, 2015
Memories are stored, at least partly, as patterns of strong synapses. Given molecular turnover, how can synapses maintain strong for the years that memories can persist?

Influence of Autapses on Synchronization in Neural Networks With Chemical Synapses

Frontiers in Systems Neuroscience, 2020
A great deal of research has been devoted on the investigation of neural dynamics in various network topologies. However, only a few studies have focused on the influence of autapses, synapses from a neuron onto itself via closed loops, on neural ...
