How Gut Bacteria Influence the Effects of Cocaine in Mice

Cocaine use supports the growth of γ-proteobacteria, a common gut bacteria that consume glycine. As glycine levels become depleted mouse models exhibit a higher response to cocaine with abnormal behaviors including increased drug-induced locomotion and drug-seeking behaviors.

Why the Memory of Fear Is Seared Into Our Brains

Norepinephrine facilitates fear processing by stimulating a population of inhibitory neurons in the amygdala, generating repetitive bursting patterns of electrical activity. This activity changes the frequency of oscillations in the amygdala from resting state to aroused state, promoting the formation of fear memories.

How stress causes gray hair

Study reveals a link between the nervous system and stem cells that regenerate pigment in hair follicles. When stressed, norepinephrine from the sympathetic nervous system causes melanocyte stem cells to activate excessively. The stem cells all convert into pigment-producing cells, prematurely depleting the reservoir. The findings explain the cellular and molecular links between stress and premature hair graying.
