Asleep in the Mouse House with Graham Diering

Memories from Diering’s life trace the rising star’s scientific path from raising lizards as a child and later exploring home brewing to heading a lab that investigates memory, sleep disturbances and early development in animals with autism-linked mutations.

Visual response shows promise as biomarker in autism-linked condition

Brain responses to visual stimuli are smaller and weaker in children with Phelan-McDermid syndrome, an autism-linked genetic condition, than in non-autistic children.

Neural network captures noisy neurons in autism mouse model

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.

The blurred line between autism and intellectual disability

Doctors often conflate autism and intellectual disability, and no wonder: The biological distinction between them is murky. Scientific progress depends on knowing where the conditions intersect — and part ways.

Sensory sensitivity in autistic people may stem from subset of neurons

Mice missing an autism gene called SHANK3 tend to be hypersensitive to touch, which may stem from underactivity of neurons that normally dampen sensory responses.

Lions and tigers and bears: Long-lived zoo animals offer a promising venue to study mental health and neurodegenerative disorders

These animals’ lifestyles often mirror those of people, making them a more relevant milieu than lab mice for determining how environmental factors influence mental health and cognitive decline. Studying them could improve animal welfare in the process.
