Null and Noteworthy: Neurons tracking sequences don’t fire in order

Instead, neurons encode the position of sequential items in working memory based on when they fire during ongoing brain wave oscillations—a finding that challenges a long-standing theory.

Null and Noteworthy: Reanalysis contradicts report of immune memory in astrocytes

The analysis, which has not yet been peer reviewed, attributes the finding to misidentified immune cells instead.

Null and Noteworthy, relaunched: Probing a schizophrenia biomarker

This edition of Null and Noteworthy—the first for The Transmitter—highlights new findings about the auditory steady-state response in people with schizophrenia that, all within one study, somehow packed in a null result and a failed replication.

The true meaning of a null result

This edition of Null and Noteworthy highlights results that reveal the difficulty in drawing definitive conclusions from data, including new findings about epidurals that contradict several others and an apparent null result on sex differences that may derive from “circular logic.”

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.

How to teach this paper: ‘Neurotoxic reactive astrocytes are induced by activated microglia,’ by Liddelow et al. (2017)

Shane Liddelow and his collaborators identified the factors that transform astrocytes from their helpful to harmful form. Their work is a great choice if you want to teach students about glial cell types, cell culture, gene expression or protein measurement.
