Epigenetics
McGowan et al. found in a post-mortem
study that expression of a
neuron-specific glucocorticoid receptor
in suicide victims. He found that suicide
(no abuse) was not significantly
different from controls, and that suicide
(abused) had significantly lower
expression of the gene for the receptor
brain changes
altered symmetry in
frontal lobes and
superior temporal gyrus
changes in neuronal density
reduction of volume in total
brain, corpus callosum,
