Computational roles of plastic probabilistic synapses [PDF]

, 2019
The probabilistic nature of synaptic transmission has remained enigmatic. However, recent developments have started to shed light on why the brain may rely on probabilistic synapses.

A Role for Dystonia-Associated Genes in Spinal GABAergic Interneuron Circuitry

Cell Reports, 2017
Spinal interneurons are critical modulators of motor circuit function. In the dorsal spinal cord, a set of interneurons called GABApre presynaptically inhibits proprioceptive sensory afferent terminals, thus negatively regulating sensory-motor signaling.

Gap junctions fine-tune ganglion cell signals to equalize response kinetics within a given electrically coupled array

iScience
Summary: Retinal ganglion cells (RGCs) summate inputs and forward a spike train code to the brain in the form of either maintained spiking (sustained) or a quickly decaying brief spike burst (transient).

Effects of calcium on drinking fluorosis-induced hippocampal synaptic plasticity impairment in the offspring of rats

Translational Neuroscience, 2017
This study investigated the effects of calcium on fluorosis-induced impairment in learning and memory of offspring rats. Methods Seventy-five newly weaned female Sprague–Dawley (SD) rats were randomly divided into five groups as follows: Control group ...

The role of microglia and their CX3CR1 signaling in adult neurogenesis in the olfactory bulb

eLife, 2017
Microglia play important roles in perinatal neuro- and synapto-genesis. To test the role of microglia in these processes during adulthood, we examined the effects of microglia depletion, via treatment of mice with the CSF-1 receptor antagonist PLX5622 ...

RNA and the synapse [PDF]

RNA, 2015
One reason we learn and remember is because synapses, the places where axons and dendrites meet, undergo experience-dependent changes whose long-lasting nature may underlie the formation and persistence of memory. Indeed, neurons use these morphological and biochemical alterations to distinguish experienced (i.e., stimulated) from naive (unstimulated ...

Distinct subpopulations of ventral pallidal cholinergic projection neurons encode valence of olfactory stimuli

Cell Reports
Summary: To better understand the function of cholinergic projection neurons in the ventral pallidum (VP), we examined behavioral responses to appetitive (APP) and aversive (AV) odors that elicited approach or avoidance, respectively.
