The rhythms generated by the stomatogastric and cardiac ganglia of the Jonah crab are surprisingly robust but differentially sensitive to acute changes in extracellular pH from pH 5.5 to 10.4.
The phase of a neuron in an oscillatory network can remain independent of network frequency when synaptic input strength and peak phase are adjusted in a frequency-dependent manner.
Neurite geometry enables expansive and highly-branched neuronal structures to operate like single electrical compartments and simple linear integrators.
Dopamine is able to ensure that neural networks maintain critical features of their output, such as synchrony of neuron firing, by directly increasing coupling strength to ensure robust output is maintained.
Neural networks like the crustacean cardiac ganglion employ multi-faceted compensatory mechanisms to achieve the stability and robustness that are critical to long-term function.
Experimental manipulations and environmental gradients, the two common-used approaches, are not at all comparable for predicting the impacts of climate change on nutrient cycling.
A genetic screen and live cell imaging show that a newly identified coiled-coil protein called SAS-7 is the earliest acting factor in centriole assembly yet identified in the roundworm Caenorhabditis elegans.
PLK-1/2-mediated SYP-4 phosphorylation is dependent on crossover precursor formation, triggering a switch in the dynamic state of the synaptonemal complex that reduces the formation of further double-strand breaks at late meiotic prophase.
