In quest for autism biomarkers, this technique has magnetic appeal
To find biological markers of autism, scientists would be wise to measure the brain's electrical activity along with the resulting magnetic fields.

When tracking brain activity, timing can be key
A brain imaging technique called magnetoencephalography characterizes not just what is happening in the brain, but also where and when, making it ideally suited for studying autism.

Imaging biomarkers could signal autism spectrum disorder
There does not appear to be a single genetic or environmental cause of autism, and given the heterogeneity of symptoms, coming up with a clear yes or no test for autism is challenging. Timothy Roberts argues that imaging and electrophysiology are key in the search for autism biomarkers.

Microglia implicated in infantile amnesia
The glial cells could explain the link between maternal immune activation and autism-like behaviors in mice, but methodological challenges prompt questions about the new evidence.

Oligodendrocytes need mechanical cues to myelinate axons correctly
Without the mechanosensor TMEM63A, the cells cannot deposit the appropriate amount of insulation, according to a new study.

Modern AI is simply no match for the complexity likely required for harboring consciousness, says Jaan Aru
He argues that our brain’s computations are of a completely different nature than any artificial intelligence because they take place across many spatial and temporal scales and are inextricably entwined with biological materials.
