Learning produces dynamic white matter volumetric changes in the rodent brain observed by voxel-based morphometry on longitudinal structural MRI for which estimated white matter volume reflects adaptive myelination in the cortex.
Colored surfaces induce strong gamma-synchronization yet sparse firing in V1 when receptive field inputs are predicted from the surrounding spatial context.
The fact that sexual activity/reproduction doubles the lifespan of certain rodent species is most likely linked to critical changes in the regulation of the hypothalamic–pituitary–adrenal stress axis.

A Traditional Chinese Medicine botanical drug exerts a competitive antagonism on the cAMP-induced modulation of sinoatrial node pacemaker channels and this functional inhibition reduces the slope of the diastolic depolarization hence spontaneous cell automaticity.
Developmental cell death plays a key role during insect neurogenesis and is increased in specific neuronal populations in flies that have evolved flightlessness.

Mice deficient in the TRPM6 channel suffer from impaired prenatal development, shortened lifespan, growth deficit and disturbed energy balance due to a defect in epithelial Mg2+ uptake, thus highlighting a pivotal role of TRPM6 in organismal Mg2+ homeostasis.
