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.
1/ #tweeprint time! If you are interested in #interneurons, #hippocampus and developmental mechanisms of neural circuit function, check out our new preprint “Hippocampal hub neurons maintain unique functional properties throughout their lifetime” biorxiv.org/content/10.110…
2/ Ten years ago, the Cossart lab discovered that rare GABAergic neurons are able to orchestrate single-handedly network dynamics in the CA3 region of the hippocampus . As these cells showed a remarkably high functional connectivity, they were termed ‘hub cells’.
3/ A few years later, @PicardoMichel and others in the lab (in collaboration with @GordFishell lab) found that many hub cells were GABA cells born early in embryogenesis (thus termed ‘early-born GABA cells’ or ‘ebGABAs’).
Hello #dendrites friends! Check out our new paper, published at @NatureComms : "Challenging the point neuron dogma: FS basket cells as 2-stage neural networks. nature.com/articles/s4146…
Briefly, we predicted through #computational simulations that the #dendrites of #Fast_spiking #interneurons in #Hippocampal #CA3 and #PFC areas come in two #nonlinear flavors: Supralinear and sublinear!
This bimodal nonlinear behavior is determined by differences in the morphology (volume) of the dendritc branches. These differences can causally enable or prohibit the existence of #sodium_spikes. Interestingly, both types coexist in all model neurons tested!
