‘Understudied secret’ in brain dampens nicotine drive in mice

The interpeduncular nucleus produces an aversion to nicotine, even at low doses, and helps moderate how rewarding mice find the drug.

Neuroscientists need to do better at explaining basic mental health research

The knowledge gap between scientists, health-care professionals, policymakers and people with mental health conditions is growing, slowing the translation of basic science to new treatments. Like lawyers learning to present a case to the court, scientists should learn to educate nonscientists about their findings.

Cocaine, morphine commandeer neurons normally activated by food, water in mice

Confirming a long-held hypothesis, repeated exposure to the drugs alters neurons in the nucleus accumbens, the brain’s reward center, and curbs an animal’s urge for sustenance.

Temperament is innate but hackable, animal studies suggest

Emotional reactivity and vulnerability to stress are largely inherited in rodents — but can be modified in early life by targeting inflammation-related cells or even just adjusting an animal’s environment.

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.

Astrocytes sense neuromodulators to orchestrate neuronal activity and shape behavior

Astrocytes serve as crucial mediators of neuromodulatory processes previously attributed to direct communication between neurons, four new studies show.
