Document Summary
The brain is capable of redesigning its architecture through synaptogenesis and neurogenesis. Synaptogenesis is the adding or destruction of synaptic connections between neurons. Neurogenesis is the adding or removal of neurons neurons added through stem cell migration and specialization - important example neural pruning around 2 years of age. The brain is capable to redesigning its build. Synaptogenesis- altering the synaptic connections between neurons. The brain has the ability to regenerate neurons, has a reservoir of stem cells this is how the brain makes new neurons. Neural pruning is when the brain kills off neurons, Epigenetics is the study of how environmental influences change gene expression. Two types of genes: structural and regulatory. Structural genes are the codes for making proteins. Ions are charged particles- sodium (na+), chloride (cl-) and potassium (k+) Diffusion is when a chemical naturally disperses throughout a medium, usually a liquid.
