Abstract: Prolonged increases in excitation can trigger cell‐wide homeostatic responses in neurons, altering membrane channels, promoting morphological changes, and ultimately reducing synaptic weights. However, how synaptic downscaling interacts with classical forms of Hebbian plasticity is still… read more here.

DOI: 10.1016/j.brs.2016.08.007
Abstract: BACKGROUND The mechanisms mediating the efficacy and variability of paired associative stimulation (PAS), thought to be mediated by Hebbian plasticity, remain incompletely understood. The magnitude and direction of Hebbian plasticity may be modulated by the… read more here.
