In astrocytes, there exists an intrinsic spatial threshold of subcellular calcium levels that triggers an astrocyte calcium surge throughout the cell, demonstrating cellular astrocyte calcium integration of time and space.
A calcium-based mechanism of neural recruitment offers a biophysical framework that unifies recent findings on respiratory rhythm generation and pattern formation by the circuitry within the brainstem.

Context factors such as experimental task and model parameterization can significantly impact modeling results, such that across tasks, the same participants show different fitted parameter values, and parameters capture different cognitive processes across tasks.
The effects of chloride homeostasis can explain diverse responses of basal ganglia output neurons to putatively inhibitory inputs and may tune these neurons' synchrony, oscillations and behavior in decision-making scenarios.

Song learning accuracy can be predicted and traced in the structural properties of the brains of juvenile male zebra finches already at 20 days post-hatching.
