Teaching signals from "tutor" brain areas should be adapted to the plasticity mechanisms in "student" areas to achieve efficient learning in two-stage systems such as the vocal control circuit of the songbird.
Vertebrate superfast muscles employ similar excitation–contraction strategies but distinct myosin heavy chain genes to allow superfast performance, revealing a maximum speed that cannot be overcome without sacrificing neural control.
Precisely sequenced patterns of neuronal activity associated with the production of a skilled behavior begin and end as part of orchestrated activity across functionally diverse populations of cortical premotor neurons.
Diminished incidence of COVID-19 amongst healthcare workers in a comprehensive screening programme demonstrates how effective infection control measures and staff testing can prevent hospitals becoming independent 'hubs' of SARS-CoV-2 transmission.
3% of >1,000 asymptomatic healthcare workers in their workplace tested positive for SARS-CoV-2, suggesting that comprehensive screening programmes are vital to prevent acquisition of COVID-19 in hospitals.
