Mirror neurons, including corticospinal neurons, in primary motor cortex of macaque monkeys, clearly dissociate between execution and observation of grasping actions while ventral premotor cortex (F5) maintains a similar representation.
When Rhesus monkeys plan reaching movements of which they are not fully confident, a particular area of the brain represents both the chosen action as well as alternate movements, perhaps as an aid for error correction or learning.
Gene expression timing during Drosophila development is specified by multiple classes of RNA polymerase II core promoters, and the embryonic transcriptome includes thousands of evolutionarily conserved long noncoding RNAs.
Adaptation along multiple task-axes reveals choice traces at millisecond resolution in non-invasive recordings from human premotor cortex and provides evidence that theories of top-down control hold even after extensive experience.
Laser-ablating neurons of a single genetic class reveals that Dbx1-derived interneurons comprise core respiratory rhythmogenic and premotor circuits and provides quantitative cellular parameters that govern network functionality
