Functional connectomics spanning multiple areas of mouse visual cortex (nature.com)
Understanding the brain requires understanding neurons’ functional responses to the circuit architecture shaping them. Here we introduce the MICrONS functional connectomics dataset with dense calcium imaging of around 75,000 neurons in primary visual cortex (VISp) and higher visual areas (VISrl, VISal and VISlm) in an awake mouse that is viewing natural and synthetic stimuli.

Fun with Logitech MX900 Bluetooth receivers (2006) (nynaeve.net)
For some time now, I have been partial to cordless mice; they’re much less of a hastle to use than “conventional” mice, especially if you use a laptop primarily.

Eating less can lead to a longer life: study in mice shows why (nature.com)
Cutting calorie intake can lead to a leaner body — and a longer life, an effect often chalked up to the weight loss and metabolic changes caused by consuming less food. Now, one of the biggest studies1 of dietary restrictions ever conducted in laboratory animals challenges the conventional wisdom about how dietary restriction boosts longevity.

Study finds grandfathers' workouts enhance grandsons' cognition in mice (psypost.org)
New research published in The Journal of Neuroscience demonstrates that the cognitive benefits of physical exercise can be transmitted transgenerationally from grandfathers to grandsons, suggesting that exercise-induced cognitive improvements may persist across multiple generations.
