motor control

Question 7

Caudal region of the ACC-

Answer 7

conflict monitoring

Question 8

Amygdala

Answer 8

emotional stimuli

Question 9

Polymorphisms

Answer 9

common gene variations (more than 1% population) which may contribute to individual differences in brain structure/ behavior

Question 10

SNPs

Answer 10

single nucleotide polymorphisms, in which a single nucleotide is substituted for another

Question 11

VNTRs

Answer 11

variable number of tandem repeats, in which certain sequences of nucleotides are repeated within a gene, but the number of repeats is variable across individuals

Question 12

An Insertion/Deletion polymorphism

Answer 12

a sequence of nucleotides is present in one variant but absent in another

Question 13

Epigenetic processes

Answer 13

Epigenetic processes- (G x E) Gene x Environment interactions
Concerned with the regulation of genes (turning genes on or off) and the transmission of genetic information

Question 14

DNA methylation

Answer 14

a methyl group is attached to the DNA w/out altering the nucleotide sequence…. The effect of the presence of the methyl group is suppression (or silencing) of the genes expression. Thus, life experience can moderate DNA methylation & gene expression
