A new behavioral model tested on mice suggests that early weaning and separation from their mothers promotes long-lasting hyperactivity and anxiety.

Researchers developed the model from observing mice and plan to use the model to investigate the long-term effects of early childhood neglect in people.

Arthur Simen and a team of researchers from Yale University School of Medicine, USA, tested their ‘Maternal separation with early weaning’ (MSEW) model in a group of 80 male mice.

He said, “Childhood adversity, in the form of abuse and neglect, is prevalent throughout the world and poses a significant public health problem. Unfortunately, the underlying molecular mechanisms of the consequences of early life neglect remain largely unknown.

“To address this, we devised a method of maternal separation that combines several published protocols in order to increase the likelihood of observing a reliable behavioral effect while minimizing fatalities to the developing offspring.”
