Homeostasis of a representational map in the neocortex - Nature Neuroscience
This study investigates how homeostatic mechanisms endow sensory representations in the auditory cortex with resilience against neuron loss. The map of sounds has the ability to recover after microablation by recruiting previously unresponsive neurons.

Spontaneous activity in brain development!

Spontaneous activity in brain development!
Experienced representations are not fully explained by a spontaneous initialization/scaffold, more like a compromise with sensory inputs. However, a critically initialized network with amplifiable, noise-reducing, long-time-scale modes provides a good and flexible starting point for learning!

When starting this project, we had a similar hypothesis! t1p.de/h5q9r, the final + updated version should be published in ~weeks. Turns out, initial sensory representations (when an animal starts to see) show little overlap with spontaneous dynamics.
Experience drives the development of novel, reliable cortical sensory representations from endogenously structured networks
Cortical circuits embody remarkably reliable neural representations of sensory stimuli that are critical for perception and action. The fundamental structure of these network representations is though...
