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.

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.

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.

Worms help untangle brain structure/function mystery
The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans.
