DYSPHORIA-BIOLOGICAL Flashcards
Brain sex theory what is the BST
Bed Nucleus of the Stria Terminalis
what does the BST do
emotional responses and sexual behaviour in male rats
how does it lead to GD
the size of the BST matches with the gender that they identify with as they always felt that they was born into the wrong sex

Women
who studied genetic factors
coolidge
coolidge asked how many twins and found what variance
157 (96 MZ 61 DZ)
found 62% of the variance could be accounted for in genetics
how many twins did Heylens study and with what concordance rate was found when one had GD
23 MZ 21DZ
39% were concordant compared to NONE of the DZ
limitation- contradictory evidence
HULSHOFF studied DURING hormone treatment and found changes in size
ZHOU studies AFTER
may just be hormone therapy
strength-other brain differences
RAMETTI- regional differences of white matter studied BEFORE hormone treatment and matched the GI
