How Ketamine Acts as Antidepressant in Chronic Pain

Chronic pain in mice activates Tiam1 in pyramidal neurons in the anterior cingulate cortex, increasing the number of dendritic spines and inducing synaptic plasticity. Ketamine's antidepressant effect in chronic pain is mediated by the drug blocking Tiam1-dependent maladaptive synaptic plasticity in ACC neurons.

Neuronal Mechanism Involved in the Learning of Maternal Behavior Discovered

Female mice who have not been pregnant or given birth show activation in the anterior cingulate cortex when they acquire maternal behaviors after exposure to pups. The findings reveal through repeated exposure to pups, virgin female mice are capable of learning maternal behaviors that resemble those of mothers following birth.
