The internal resistance of axons to ionic current flow determines action potential conduction velocity. Although mitochondria support axonal function, axons have been modeled as organelle-free cables, and mitochondrial impact on conduction velocity, specifically by increasing internal resistance, remains understudied. We combine computational modeling and electron microscopy of forebrain premotor axons controlling birdsong production.

Racial stereotypes have been shown to bias the identification of innocuous objects, making objects like wallets or tools more likely to be identified as weapons when encountered in the presence of Black individuals. One mechanism that may contribute to these biased identifications is a transient perceptual distortion driven by racial stereotypes. Here we provide neuroimaging evidence that a bias in visual representation due to automatically activated racial stereotypes may be a mechanism underlying this phenomenon.

Getting caregivers to respond to their pain cries is vital for the human baby. Previous studies have shown that certain features of baby cries-the nonlinear phenomena (NLP)-enable caregivers to assess the pain felt by the baby. However, the extent to which these NLP mobilize the autonomic nervous system of an adult listener remains unexplored.
