Abstract: Latency reduction in postsynaptic spikes is a well-known effect of spiking time-dependent plasticity. We expand this notion for long postsynaptic spike trains on single neurons, showing that, for a fixed input spike train, STDP reduces… read more here.

DOI: 10.1016/j.clinph.2016.10.404
Abstract: Question Learning may occur through associative changes in the synaptic strength of neural connections that can be induced by coupling of activity of interconnected neurons with precise timing (spike-timing dependent plasticity, STDP). It is debated… read more here.

DOI: 10.1016/j.clinph.2018.04.604
Abstract: OBJECTIVE To determine whether a single dose of fluoxetine increases corticomotoneuronal excitability, motor performance and practice-dependent plasticity. METHODS Twelve healthy adults completed this placebo-controlled, pseudo-randomized, double-blind crossover study. Transcranial magnetic stimulation (TMS) was used to… read more here.

DOI: 10.1016/j.neuroscience.2020.10.032
Abstract: Studies of cortical function-recovery require a comparison between normal and post-stroke conditions that lead to changes in cortical metaplasticity. Focal cortical stroke impairs experience-dependent plasticity in the neighboring somatosensory cortex and usually evokes periinfarct depolarizations… read more here.
