1) What are the different neural progenitor fates that are specified along the dorsal-ventral axis of the neural tube? Why is it important - what are the different neural fates that have to be made?

2) How are different neural fates specified in the ventral half of the neural tube?

Answer #1

1) Neural plate rolls up from the Neural tube.

  • Patter of regional cell identity becomes apparent along the dorsal ventral axis.
  • Distinct populations of proginator cells give rise to post-mitotoc neurons with diatdist functional properties.
  • Distinct cell types form in a bilaterally symmetrical way with respect to the ventra midline.

    For the Speech Neural Network, please describe the possible impairments associated with disruptions to each cortical region below. In your description, you should include what processes that will be degraded/damaged (including upstream processes) and what processes will continue to function. This is especially important in terms of the dorsal, ventral stream for speech perception/production. (Hint #1: do not just consider where the damage is located in terms of cortical region -- also consider whether the damage is bilateral or unilateral....
