Null and Noteworthy: Downstream brain areas read visual cortex signals en masse in mice

The finding contradicts a theory that the regions prioritize neurons that are adept at identifying specific stimuli. Plus, a response to a study that questioned immune memory in astrocytes.

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: Learning theory validated 20 years later

The first published paper from the #EEGManyLabs replication project nullifies a null result that had complicated a famous reinforcement learning 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The analysis, which has not yet been peer reviewed, attributes the finding to misidentified immune cells instead.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: Reexamining registered reports

Out of 92 preregistered studies that resulted in published papers, only 15 had fully adhered to their preregistration details, according to a new analysis.

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.

U.S. national primate research centers face an uncertain future

The facilities were meant to last 100 years. Four decades shy of that mark, amid flatlined funds and mounting political pressure, their directors are trying to find a path forward.
