Neural plate
the first stage of neural development occurs w/in the first 18 days of development
continued development from the neural plate
the neural plate invaginated and eventually becomes a tube.
how long does it take the amygdala to develop?
before age 5
how long does it take the frontal cortex to develop?
not fully developed until ~20 years of age
When and why can someone be tried for the death penalty?
under the age of 18 a person cannot be sentenced to death because the part of their brain (frontal cortex) responsible for criminal judgment is not fully developed. They are still thinking emotionally w/ their amygdala
epigenesis
refers to a process of a structure becoming increasingly more specialized, conditions at one stage set conditions for the next. this is seen as the neural plate progresses from a plate to the brain and spinal cord.
When and where are neurons born?
along the lining of the ventricles, central canal, and the aqueducts that connect the ventricles. Most are born very early (w/in a few days after birth), but some exceptions include the olfactory bulb, hippocampus, amygdala, and possibly the neocortex.
what kind of experiences can increase or decrease neuron birth in adult animals?
puberty?
what changes occur in the neuron during differentiation?
change in shape, type of transmitters they release, receptors they have ect.
Mitotic lineage means that the cells fate is predetermined based on the differentiation of its predecessors.
Induction involves environmental direction of gene expression.
after birth where do neurons go? how?
chemicals lead the way whether on substrates of diffused by other cells. Glial cells provide a scaffold to help direct the neurons to their proper location.
chemical cues and growth cones
cues lead the growth cone of an immature neuron to a synapses
chemoaffinity hypothesis
Roger Sperry said that....
