Ongoing activity in the neonatal mouse cerebral cortex is characterized by discrete domains
- Cortical column (mini/meso/super columns) history (20th century anatomists).
- Column physiology-- Hubel and Wiesel. Rodent V1?
- Developmental studies-- fetal monkey ODCs.
- Rodent barrels (early anatomical emergence from TC input, functional/physiological emergence?). * What is known about columns/domains in secondary/association/non-primary sensory representations? Rest of rodent S1 (non-barrel cortex?).
- Calcium domains of Yuste, Science 1992 paper.
- Other slice calcium recordings, patch/gap junctions. In vivo physiology? (Not too many multisite electrode recordings in cortex, spatial resolution issue).
- Calcium imaging-- Konnerth 'waves' in Ent cortex. For visual cortex, domains activity in extrastriate cortex (Ackman Nature 2012). But S1-- Golshani work in later postnatal-- but activity not obeying domains in barrel cortex-- problem with spatial sampling in the xy and the z for this study?
