Spatial learning circuitry fluctuates in step with estrous cycle in mice
Cyclic shifts in estradiol levels coincide with changes in dendritic spine density and the activity of place cells in the CA1 region of the hippocampus, a new study shows.

What birds can teach us about the ‘biological truth’ of sex
Part of our job as educators is to give students a deeper understanding of the true diversity of sex and gender in the natural world.

Keep sex as a biological variable: Don’t let NIH upheaval turn back the clock on scientific rigor
Even in the absence of any formal instruction to do so, we should continue to hold our ourselves and our neuroscience colleagues accountable for SABV practices.

Structure of striatum varies by sex in autistic children
The changes could reflect different developmental trajectories between boys and girls with autism, a new study suggests.

Exclusive: NIH appears to archive policy requiring female animals in studies
Such a shift would “put us back in the dark ages in terms of our science,” says neuroscientist Anne Murphy, who helped to formulate the original policy.

Revisiting sex and gender in the brain
To conduct scientifically accurate and socially responsible research, it is useful to think of “sex” as a complex, multifactorial and context-dependent variable.

Dose, scan, repeat: Tracking the neurological effects of oral contraceptives
We know little about how the brain responds to oral contraceptives, despite their widespread use. I am committed to changing that: I scanned my brain 75 times over the course of a year and plan to make my data openly available.

X marks the spot in search for autism variants
Genetic variants on the X chromosome, including those in the gene DDX53, contribute to autism’s gender imbalance, two new studies suggest.

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.
