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.

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.

Null and Noteworthy: Mind reading, specialist shortage, sleep problems source

This month, a commonly used emotion-recognition test doesn’t perform as expected — nor does a survey of past efforts to train autism specialists or a hunt for the sources of the sleep problems that often accompany the condition.

How to teach this paper: ‘Behavioral time scale synaptic plasticity underlies CA1 place fields,’ by Bittner and Milstein et al. (2017)

Katie Bittner, Aaron Milstein and their colleagues found that cellular learning can happen over longer timescales than Hebb’s rule predicts. How long should we wait to teach students about this phenomenon?
