The Phylogenetics of Dynamics in DNA Clamp Proteins [PDF]

open access: yesStructure, 2014
Using HXMS to measure protein dynamics, Fang and colleagues (in this issue of Structure) probe the dynamics of processivity clamp proteins from all kingdoms of life. The proteins have similar structures but divergent sequences. Their results show conserved dynamics correlating with primary functions and divergent dynamics for divergent functions.

Hidden synaptic differences in a neural circuit underlie differential behavioral susceptibility to a neural injury

open access: yeseLife, 2014
Individuals vary in their responses to stroke and trauma, hampering predictions of outcomes. One reason might be that neural circuits contain hidden variability that becomes relevant only when those individuals are challenged by injury.

Pacemaker neuron and network oscillations depend on a neuromodulator-regulated linear current

open access: yesFrontiers in Behavioral Neuroscience, 2010
Linear leak currents have been implicated in the regulation of neuronal excitability, generation of neuronal and network oscillations, and network state transitions.

Preproteins couple the intrinsic dynamics of SecA to its ATPase cycle to translocate via a catch and release mechanism

open access: yesCell Reports, 2022
Summary: Protein machines undergo conformational motions to interact with and manipulate polymeric substrates. The Sec translocase promiscuously recognizes, becomes activated, and secretes >500 non-folded preprotein clients across bacterial cytoplasmic ...

Dynamics of a clamped–clamped microbeam resonator considering fabrication imperfections [PDF]

open access: yesMicrosystem Technologies, 2014
We present an investigation into the static and dynamic behavior of an electrostatically actuated clamped---clamped polysilicon microbeam resonator accounting for its fabrication imperfections, which are commonly encountered in similar microstructures.

Synchronisation through nonreciprocal connections in a hybrid hippocampus microcircuit

open access: yesFrontiers in Neural Circuits, 2013
Synchronisation among neurons is thought to arise from the interplay between excitation and inhibition; however, the connectivity rules that contribute to synchronisation are still unknown.

Ultrarapid Delayed Rectifier K+ Channelopathies in Human Induced Pluripotent Stem Cell-Derived Cardiomyocytes

open access: yesFrontiers in Cell and Developmental Biology, 2020
Atrial fibrillation (AF) is the most common cardiac arrhythmia. About 5–15% of AF patients have a mutation in a cardiac gene, including mutations in KCNA5, encoding the Kv1.5 α-subunit of the ion channel carrying the atrial-specific ultrarapid delayed ...

Diversity of intrinsic frequency encoding patterns in rat cortical neurons : mechanisms and possible functions [PDF]

open access: yes, 2010
Extracellular recordings of single neurons in primary and secondary somatosensory cortices of monkeys in vivo have shown that their firing rate can increase, decrease, or remain constant in different cells, as the external stimulus frequency increases ...

Patch-clamp and multi-electrode array electrophysiological analysis in acute mouse brain slices

open access: yesSTAR Protocols, 2021
Summary: Patch-clamp and multi-electrode array electrophysiology techniques are used to measure dynamic functional properties of neurons. Whole-cell and cell-attached patch-clamp recordings in brain slices can be performed in voltage-clamp and current ...

The dendritic location of the L-type current and its deactivation by the somatic AHP current both contribute to firing bistability in motoneurons

open access: yesFrontiers in Computational Neuroscience, 2014
Spinal motoneurons may display a variety of firing patterns including bistability between repetitive firing and quiescence and, more rarely, bistability between two firing states of different frequencies.
