‘Zombie’ pig brains fire hours after death
A new method restores blood flow and some functions in pig brains four hours after the animals have died.
New method creates complex, long-lived brain ‘organoids’
A new method for growing brain organoids allows them to survive for up to a year — more than four times as long as is possible with other methods.

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.

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.
