Scared Rat Smells Calm Rat Pheromones Humane Pest Control Study University of Tokyo

Several animals release pheromones, which are endogenous chemical substances secreted by one individual and received by a second individual of the same species, eliciting a response in the latter due to behavioural or hormonal changes. How pheromones released from calm rats help reduce fear in scared rats Rats have relatively high intelligence compared to other mammals, which makes them fascinating animals to study, and understand mechanisms occurring in humans. A new study explains how "calm is contagious" in rats, for a pheromone released by relaxed rats can calm scared and stressed rats Several rats suffer from neophobia, which is the fear of new things. Researchers observed the mechanism through which the 2-MB pheromone helps calm stressed rats using microscopic images from the rats' amygdala, which is the brain site for regulating fear responses. How this pheromone could lead to humane pest control After this, the researchers tested if the same behaviour was observed in wild rats in urban environments.
