1neurogenesis
mitosis produces new neurons
2progenitor cells
divide and move out of ventricular zone to become the embryo for new neuron
3cell migration
cells move to establish distinct populations
4radial glial cells
help developing neurons move to the right place in developing brain
5gonadotropin releasing hormone (GnRH) in females
6gonadotropin releasing hormone (GnRH) in males
9sonic hedgehog
gene that regulates cell differentiation
10sonic hedgehog gradient
11cell death
selective death of some nerve cells
12apoptosis
meuron turns on a set of genes that result in the production of caspases that destroy the cell (planned)
13necrosis
the neuron dies as a result of an injury or trauma (accidental)
14cortical development
within subject study to track brain development in children via MRI every 2 years for ages 2-8 yrs old
15synaptic pruning and autism
16Fragile X syndrome
lack of proteins produced by the promotor region
17FMR-1 function
inhibition of protein synthesis, especially in synthesis
