While the striatum and orbitofrontal cortex learn about threats through verbal warnings, the amygdala learns only from direct experience, suggesting that the amygdala forms part of a specialized threat detection system.
A comprehensive analysis of long noncoding RNAs in the hematopoietic system reveals their dynamic regulation and a loss-of-function screen identifies some required for leukemia progression and involved in normal myeloid differentiation.
The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.
Experiments and mathematical modelling show that rare nitrogen fixing symbionts invade a population dominated by non-fixing bacteria across plant generations, above a threshold of a combination of ecological factors.
Systematic and coordinated variations in morphology and connectivity can structurally tune a microcircuit's computation but non-systematic variably also exists, imparting "connection noise" that potentially limits processing performance.
