DOI: 10.1007/s00221-021-06238-x
Abstract: During voluntary contractions, limb muscle motor unit (MU) firing rates accelerate over a small force range and saturate in response to increasing contraction intensity. In comparison, facial muscles are cranially innervated, and some function without… read more here.

DOI: 10.1016/j.neuron.2020.11.001
Abstract: Homeostatic plasticity is hypothesized to bidirectionally regulate neuronal activity around a stable set point to compensate for learning-related plasticity, but to date only upward firing rate homeostasis (FRH) has been demonstrated in vivo. We combined chronic… read more here.

DOI: 10.1038/s41598-019-43460-8
Abstract: Thalamocortical (TC) relay cells exhibit different temporal patterns of activity, including tonic mode and burst mode, to transmit sensory information to the cortex. Our aim was to quantify the metabolic cost of different temporal patterns… read more here.

Abstract: Advances in surface electromyographic (EMG) signal decomposition allow researchers to analyze data for 20-50 motor units per contraction. To simplify interpretation, some investigators rely on group mean analysis of the mean firing rate versus recruitment… read more here.

Abstract: Persistent inward calcium and sodium currents (IP) activated during motoneuron recruitment help synaptic inputs maintain self-sustained firing until de-recruitment. Here, we estimate the contribution of the IP to self-sustained firing in human motoneurons of varying… read more here.

DOI: 10.1371/journal.pbio.2005239
Abstract: Natural sensory stimuli frequently consist of a fast time-varying waveform whose amplitude or contrast varies more slowly. While changes in contrast carry behaviorally relevant information necessary for sensory perception, their processing by the brain remains… read more here.

DOI: 10.1371/journal.pcbi.1005506
Abstract: A central question in neuroscience is to understand how noisy firing patterns are used to transmit information. Because neural spiking is noisy, spiking patterns are often quantified via pairwise correlations, or the probability that two… read more here.

DOI: 10.1371/journal.pcbi.1010590
Abstract: Neural circuits exhibit complex activity patterns, both spontaneously and evoked by external stimuli. Information encoding and learning in neural circuits depend on how well time-varying stimuli can control spontaneous network activity. We show that in… read more here.
