New ‘decoder’ tool translates functional neuroimaging terms across labs

The compendium of brain-parcellation atlases makes it possible to compare large-scale network data, which often involves different and overlapping network names.

To develop better nervous-system visualizations, we need to think BIG

With a full mouse connectome on the horizon, neuroscience needs to overcome its legacy of minimalism and embrace the contemporary challenge of representing whole-nervous-system connectivity.

How to teach this paper: ‘Behavioral time scale synaptic plasticity underlies CA1 place fields,’ by Bittner and Milstein et al. (2017)

Katie Bittner, Aaron Milstein and their colleagues found that cellular learning can happen over longer timescales than Hebb’s rule predicts. How long should we wait to teach students about this phenomenon?

Widely used calcium imaging protocol can lead to spurious results, new paper cautions

The technique, which measures calcium currents as a proxy for neuronal firing, sometimes reports unusual and potentially misleading waves of activity in the hippocampus.

To improve big data, we need small-scale human imaging studies

By insisting that every brain-behavior association study include hundreds or even thousands of participants, we risk stifling innovation. Smaller studies are essential to test new scanning paradigms.
