Topographic organization of human subcortex

Tian and colleagues used functional MRI to unveil the extraordinarily complex layout of the human subcortex, identifying 27 new functional regions and four scales of hierarchical organization that adapt to changing cognitive demands. The cover art illustrates functional regions of the human subcortex delineated at Scale I (left) and Scale IV (right).

    Chiot and colleagues investigated whether peripheral macrophages play a role in amyotrophic lateral sclerosis (ALS) pathology, finding that macrophages along peripheral motor neuron axons react to neurodegeneration. Modifying reactive oxygen species (ROS) signaling in peripheral macrophages, using bone marrow cell replacement, reduces both macrophage and microglia inflammatory response, delays pathology and increases survival in ALS mouse models.

    Abrupt spatial changes in anatomic and functional properties of the brain demarcate boundaries between discrete functional areas. While previous work has identified these boundaries in cortex, a new study by Tian et al. applies this approach for the first time to subcortical structures within the in vivo human brain.

    Aggression is an instinctive behavior supported by hardwired neural circuits. Julieta Lischinsky and Dayu Lin review our current understanding of the neural circuits of aggression across species and their modulation by internal state.

    By analyzing hundreds of mice treated with a library of neuro- and psychoactive drugs, Wiltschko et al. show that Motion Sequencing can effectively discriminate and categorize drug effects and link molecular targets to behavioral syllables.
