Neural network captures noisy neurons in autism mouse model

by  /  18 June 2021

Mice missing the autism-linked gene SHANK3 use more neurons to engage in social behavior than control mice do, reflecting a more disorganized, less efficient brain signaling network.

Dopamine neurons may dampen social behavior in mouse model of autism

by  /  12 January 2021

Mice missing a copy of the autism-linked gene PTEN show a reduced preference for social interaction, possibly due to atypically large, overconnected dopamine neurons. Easing the overconnection may alleviate this trait.
