Fueling Synapses [PDF]

open access: yesCell, 2004
The transmission of information across neuronal synapses is an energetically taxing business. Sheng and colleagues monitored the localization of mitochondria following different levels of synaptic activation and discovered that these organelles change their distribution in interesting ways, stalling near synapses when neurons are activated and ...

Developmental Changes of Human Neural Progenitor Cells Grafted into the Ventricular System and Prefrontal Cortex of Mouse Brain in Utero

open access: yesCells, 2023
The transplantation of neural progenitors into a host brain represents a useful tool to evaluate the involvement of cell-autonomous processes and host local cues in the regulation of neuronal differentiation during the development of the mammalian brain.

Functional maturation of human iPSC-derived pyramidal neurons in vivo is dependent on proximity with the host tissue

open access: yesFrontiers in Cellular Neuroscience, 2023
Human induced pluripotent stem cells (hiPSCs) have been used extensively in vitro to model early events in neurodevelopment. Because of a number of shortcomings, previous work has established a potential to use these cells in vivo after transplantation ...

The Dynamic Synapse [PDF]

open access: yesNeuron, 2013
The constant dynamic movement of synapses and their components has emerged in the last decades as a key feature of synaptic transmission and its plasticity. Intramolecular protein movements drive conformation changes important to transduce transmitter binding into signaling. Constant cytoskeletal rearrangements power synapse shape movements.

The role of peptidyl-prolyl isomerase Pin1 in neuronal signaling in epilepsy

open access: yesFrontiers in Molecular Neuroscience, 2022
Epilepsy is a common symptom of many neurological disorders and can lead to neuronal damage that plays a major role in seizure-related disability.

Noise-modulated multistable synapses in a Wilson-Cowan-based model of plasticity

open access: yesFrontiers in Computational Neuroscience, 2023
Frequency-dependent plasticity refers to changes in synaptic strength in response to different stimulation frequencies. Resonance is a factor known to be of importance in such frequency dependence, however, the role of neural noise in the process remains

Decoding Synapses [PDF]

open access: yesThe Journal of Neuroscience, 1996
The strength of many synapses is modified by various use and time-dependent processes, including facilitation and depression. A general description of synaptic transfer characteristics must account for the history-dependence of synaptic efficacy and should be able to predict the postsynaptic response to any temporal pattern of presynaptic activity.

Nanomachinery Organizing Release at Neuronal and Ribbon Synapses [PDF]

open access: yes, 2022
A critical aim in neuroscience is to obtain a comprehensive view of how regulated neurotransmission is achieved. Our current understanding of synapses relies mainly on data from electrophysiological recordings, imaging, and molecular biology.

Aberrant Synaptic Pruning in CNS Diseases: A Critical Player in HIV-Associated Neurological Dysfunction?

open access: yesCells, 2022
Even in the era of effective antiretroviral therapies, people living with Human Immunodeficiency Virus (HIV) are burdened with debilitating neurological dysfunction, such as HIV-associated neurocognitive disorders (HAND) and HIV-associated pain, for ...

Electrochemistry at the Synapse [PDF]

open access: yesAnnual 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.
