stress

Physiological and behavioral evidence of stress. Left: Schematics of two-photon imaging during baseline and repetitive stress conditions. In repetitive stress sessions, the mice were placed in a 50 ml tube for 30 min to achieve mild stress. The imaging session started directly after the restraint. Individual cells were tracked over imaging days. Shown are examples of 2 imaging planes on day 1 and day 9 (scale bar, 50 μm) and the noise-evoked responses of 3 exemplar cells (mean ± SE).

How Stress Alters Memories: Insights from Neuroscience

Mitochondria release segments of mitochondrial DNA that can travel through pores of the nucleus and integrate into a cell's chromosomes (where the insertions are called NUMTs, for nuclear mitochochondrial segments). A new study has found that nuclear mitochondrial DNA insertion—once thought rare—happens in the human brain likely several times over during a person’s lifespan.
