Synaptic remodeling induced by gonadal hormones: neuronal plasticity as a mediator of neuroendocrine and behavioral responses to steroids.
Árpád Párducz,Tibor Hajszan,Tibor Hajszan,Neil J. MacLusky,Zsófia Hoyk,Eszter Csakvari,Anita Kurunczi,Janine Prange-Kiel,Csaba Leranth +8 more
TL;DR: Current knowledge and the most significant recent discoveries from laboratories on estrogen- and dehydroepiandrosterone-induced synaptic remodeling in the hypothalamus and hippocampus, two important brain areas heavily involved in autonomic and cognitive operations, respectively are summarized.

The highly sialylated isoform of the neural cell adhesion molecule is required for estradiol-induced morphological synaptic plasticity in the adult arcuate nucleus.
TL;DR: The results provide strong evidence that the presence of large quantities of the PSA moiety on NCAM is a necessary prerequisite for estrogen‐induced phasic remodelling of synapses in the adult female arcuate nucleus.

Hormonal enhancement of neuronal firing is linked to structural remodelling of excitatory and inhibitory synapses.
TL;DR: Results indicate that oestrogen modifications in firing frequency in arcuate neurons are temporally linked to anatomical modifications in the numerical balance of inhibitory and excitatory synaptic inputs.

Behavioral and neurotoxicological effects of subchronic manganese exposure in rats.
TL;DR: By applying a complex set of methods, it was possible to obtain new data for a better-based relationship between the known effects of Mn at neuronal level and the behavioral and electrophysiological outcomes of Mn exposure.

Fluctuation of synapse density in the arcuate nucleus during the estrous cycle.
Eszter Csakvari,Zsófia Hoyk,Andrea Gyenes,Daniel Garcia-Ovejero,Luis M. Garcia-Segura,Árpád Párducz +5 more
TL;DR: Results indicate that a rapid and selective synaptic turnover of arcuate synapses occurs in physiological circumstances and appears to cycle back to proestrus morning values on metestrus day.
