Question Answered step-by-step we begin a discussion of the nervous system including the role of… we begin a discussion of the nervous system including the role of neurotransmitters in the transmission of nerve impulses.  We know that dopamine is a neurotransmitter that is associated with control of emotions and complex movements.  And dopamine also suppresses the responsiveness of neurons to new inputs of stimuli.  Some researchers believe that people who exhibit symptoms associated with Attention-Deficit/Hyperactivity Disorder (ADHD) may have abnormal levels of dopamine; someone with low dopamine levels may respond impulsively and without focus.While there may be biological differences in the brains of those with ADHD, others wonder if environmental factors exacerbate the ADHD situation.  In the last decade, the number of people diagnosed with ADHD has increased dramatically.  An increase of this magnitude is unlikely to be due to biological factors alone.Read a few articles on the Internet regarding the roles of biology and the environment on the incidence of ADHD in the population.  –Do you believe that ADHD is caused by biology alone (i.e., abnormal levels of a neurotransmitter), the environment alone (e.g., increased pressure on children), or a combination of the two?   Include the citations of any references (at least one, not Wikipedia or the textbook) that you used in your research.  Science Biology BIOL 141 Share QuestionEmailCopy link Comments (0)
