Developing Human Cerebellum

(A–X) A greater EGL cell density and reduced EGL thickness were reported in preterms with ex-utero exposure, as compared to their age matched stillborn controls. ML thickness was increased in preterms with ex-utero exposure born after 34 weeks gestation, as compared to their age matched controls. Compare E with F, G with H and I with J.

Abbreviations

  • wk = number of gestational weeks
  • d = number of postnatal days
  • mon PN = postnatal months - born at term
  • EGL = external granular layer
  • ML = molecular layer
  • PL = purkinje cell layer
  • IGL = internal granular layer
