Consider the glia limitans superficialis (GLS), the thin layer of cells that covers the brain and spinal cord just beneath the protective meninges.

The goal of publishing careful replications—and, humbly, of this newsletter—is to gain a more accurate scientific picture of reality. Adhering closely to original methodologies and reporting all results are key, but often overlooked, steps in this process. Enter preregistration, a process whereby researchers publish their intended methods before they begin their experiments, enabling the research community to evaluate how and why any subsequent deviations occurred.

Hunched over a microscope more than a century ago, Santiago Ramón y Cajal discovered that distinct types of neurons favor different brain regions. Looking at tissue from a pigeon’s cerebellum, he drew Purkinje cells, their dendrites outspread and twisted like a ravaged oak. And drawing from another sample—the first cortical layer of a newborn rabbit’s brain—he traced the tentacled nerve cells that would later bear his name.

Contributing writer Share this article: Welcome to Null and Noteworthy, a monthly newsletter about neuroscience research that fails to support a hypothesis or replicates a previously proposed one. Though these studies are typically less splashy than those that many journals publish, they often bring more nuance and complexity to the field by exposing cracks in or solidifying previous findings.
