Was it the fault of bad brain chemistry or life's buffetings?
Many blame bad parenting, whereas others point the finger at disorders of brain chemistry or hormonal disturbances in the womb.
I've read that it's a matter of brain chemistry or some incident unresolved.
Electrical stimulation seems to change brain chemistry and function, but without knowing exactly how, it's impossible to know how it leads to better learning or recovery.
"And why should it surprise us that medications that can change brain chemistry and function might alter the development of the brain and behavior?" Dr. Urato argues that the risks of antidepressant use during pregnancy outweigh what he sees as the limited benefits.
Then will come dipsticks for the genes that control hormone levels, brain chemistry, nerve functions and metabolic rates which, in turn, affect stress, pleasure, irritability, aggression, impulsive behavior, suicidal tendencies, alcoholism and sexual proclivities.
They include conduction of electromagnetic signals, activation of opioid systems or changes in brain chemistry, sensation and involuntary body functions.
A set of traits and behaviors, at least some of which were once regarded as neutral or even desirable, re-emerged as a pathology -- a function of brain chemistry, amenable to and indeed demanding pharmacological manipulation.
Rate of growth and sexual maturation, hormone levels in blood, reproductive organ function, fertility, immune function, enzyme activity, brain structure, brain chemistry, and behavior are all affected by exposure to low doses of BPA.
Many of the adverse effects observed (sexual maturation, hormone levels in blood, fertility, immune function, enzyme activity, brain chemistry, behavior, etc).
