All vertebrate #brains have #parvalbumin #interneurons, but in mammals they play a critical role in the function of the #cortex. @ellie_bucher‘s debut paper in Brain Structure and Function surveys the field to tell this emerging and exciting story. rdcu.be/cni5M 
Parvalbumin equips these #neurons for sustained fast firing, synchronizing large areas of cortex to focus attention. Linked in vast networks which buzz with gamma #oscillations, their outputs target cell bodies and axons of principal neurons to control their interactions.
Uniquely among interneurons, #perineuronal nets and #myelin anchor and stabilise the cell bodies and axons of basket cells, tightly regulating #plasticity to bind their networks into functional structures after critical periods pass.
