Epigenetic code - (ANSWER)A second code governing protein production through environmental
influences that block (suppress) the expression of some genes and unlock the expression of others.
Human genome - (ANSWER)Composed of approximately 20,000 genes.
Brain trauma result - (ANSWER)Muscle weakness, spasticity, and/or rigidity of the left side of the body
as seen in R.S. would likely result from damage to the precentral gyrus.

UDATE!!
Brain lesion effects - (ANSWER)A brain lesion on the right side of the motor cortex leading to
impairment in motor function of the left arm and leg can be considered contralateral and efferent.
EQs larger than 1.0 - (ANSWER)Mammals with EQs larger than 1.0 would most likely have a larger brain
than is expected for mammals of that particular body weight.
Thalamus function - (ANSWER)Sensory relay.
Basal ganglia function - (ANSWER)Controlling movement and associative learning.
Hippocampus function - (ANSWER)Personal memory formation.
Corpus callosum function - (ANSWER)Interhemispheric connections.
Phenotypic plasticity - (ANSWER)Accounts for the way that identical genotypes do not produce identical
phenotypes.
Mendelian genetics theory - (ANSWER)Experience cannot be inherited, but it appears that through
epigenetic mechanisms it can be inherited.
Genetic mutations - (ANSWER)Sometimes both disruptive and beneficial.
Spinal cord segments - (ANSWER)There are 31 spinal cord segments.
Frontal lesions behavior - (ANSWER)The tendency of patients with frontal lesions to engage in
inappropriate behaviors may be attributed to difficulties in guiding behavior using social context.
