Sounding the alarm on pseudoreplication: Q&A with Constantinos Eleftheriou and Peter Kind

Most studies of neurological disorders in mice erroneously treat multiple samples from a single animal as independent replicates, according to a new analysis. But scientists and journals can take steps to curb this practice.

Is excess brain fluid an early marker of autism?

Brain scans of hundreds of infants suggest that up to 80 percent of those with autism have unusual amounts of cerebrospinal fluid. Researchers are studying how this might contribute to the condition.

Prenatal exposures; Angelman trial suspension; autistic adult well-being

This month’s issue of the Null and Noteworthy newsletter breaks down some negative results involving prenatal exposures, an experimental treatment for Angelman syndrome, and the role that age at autism diagnosis plays in subsequent outcomes, and more.

Head direction cells stably orient mice to outside world

The cells’ representations show little drift over time—unlike those of other navigation system neurons—and may provide a “rigid backbone” for more flexible sensory and cognitive responses.

Juan Gallego discusses how manifolds are transforming our understanding of the coordination of neuronal population activity

A wealth of evidence supports the view that neural manifolds are real and useful, Gallego says, even if they may not completely solve the age-old mind-body problem.
