Neurodevelopment Crossword

The generation of new neurons.
The part of the ectoderm that gives rise to the nervous system.
Cell bodies of cortical neuroscience s are always arranged in these sheets that lie parallel to the brain.
The process in which the cortex forms from two layers in early development to a full 6 layers. Each layer going through the subplate and subsequent layers until they hit the cortical plate. Beginning with the 6th layer and ending with the first layer replacing the cortical plate.
Pieces of neural ectoderm that are pinched off when the neural tube rolls up. Gives rise to the PNS.
A tube of neural ectoderm in an embryo that will give rise to the CNS.
The process of neurons moving from where they are created to their final place in the brain. Radial or Tangential.
The process of the neural ectoderm forming into the neural tube.
Cells that divide to create all of the neurons and astrocytes of the cerebral cortex. Neural progenitors.
One of the three layers of cells in an embryo. Gives rise to the skin and the nervous system.
Radial glial cells. Divide to create all of the neurons and astrocytes of the cerebral cortex.
The rostral end of the neural tube differentiates to form three primary and two secondary of these. They will give rise to the entire brain. Prosencephalon (comprised of Telencephalic, Diencephalon, and Optic), Mesencephalon, Rhombencephalon.
One of only two layers that make up the walls of the ventricles in early development. Faces the pia mater.
A backup of CSF causing the ventricles to swell. Term originally meaning “water head”.
A cell layer of the immature cerebral cortex containing undifferentiated neurons. The “stop signal for cells finding their layer of cerebral cortex during inside-out formation.
A layer of cortical neurons lying below the cortical plate early in development. All cells going to their final layer in the cerebral cortex must pass through this.
A layer of cortex in the neural tube between the ventricular zone and the pia mater. Neural precursor cells follow thin fibers put out by radial glial cells through this area.
One of two layers that make up the ventricles early in development. Lines the inside of the ventricles.
The process of multipotent stem cells dividing to create more neural progenitors.
Later in development. One daughter cell goes to its position in the cortex and stops dividing while the other daughter cell stays in the ventricular zone and continues dividing.
The process of neural progenitors growing and dividing into daughter cells.
The process of pioneer axons growing in segmented pieces to find their next target and eventually reach their final destination by “connecting the dots”.
Specialized tip of a growing neurite. Directs the growth of the neurite towards attractive cues.
The idea that chemical markers on growing axons are matched with complementary chemical markers on their targets to establish precise connections.
The process of a growing axons being attracted to a chemoattractant and following it toward their target.
A diffusible molecule that acts over a distance to attract growing axons toward their targets using chemical signaling. An example is Netrin in the ventral midline of the spinal cord.
A thin tube extending from a neuronal cell body; the two types are axons and dendrites.
The process of a growing axons being repelled by a chemorepellent and moving away from it and toward their target.
