Juveniles/Elderly & Psychopharmacology•1-5 children between ages 5 to 17 may have some type of mental disorder•Increase in numbers could be due to increased awareness of mental health in society orchanges in criterion used for diagnosing•Only a few psychotropic drugs have been tested for safety/efficacy withchildren/adolescents
ASUS Review: PSYC 100 Review Booklet41•Metabolism of drugs is often slowed forelderly populations (less drug = sameeffect or too much of a drug = many sideeffects)•Dizziness (side effect) can cause falling(greater risk for elderly) and may reducebone densityWeek 5 Questions:5.1:Which is the most common type of neuron?

Week 6 Definitions:The Brain•Ablation –surgical removal of brain tissue•Basal ganglia –subcortical structures of the cerebral hemispheres involved in voluntarymovement•Brain stem –the “trunk” of the brain comprised of the medulla, pons, midbrain, anddiencephalon•Callosotomy –surgical procedure in which the corpus callosum is severed (used to control severeepilepsy)•Case study –a thorough study of a patient (or a few patients) with naturally occurring lesions•Cerebellum –the distinctive structure at the back of the brain, Latin for “small brain”
ASUS Review: PSYC 100 Review Booklet42•Cerebral cortex –the outermost gray matter of the cerebrum; the distinctive convolutionscharacteristic of the mammalian brain•Cerebral hemisphere –the cerebral cortex, underlying white matter, and subcortical structures•Cerebrum –usually refers to the cerebral cortex and associate white matter, but in some textsincludes the subcortical structures•Contralateral –“opposite side”; used to refer to the fact that the two hemispheres of the brainprocess sensory information and motor commands for the opposite side of the body•Converging evidence –similar findings reported from multiple studies using different methods•Diffuse optical imaging (DOI) –a neuroimaging technique that infers brain activity bymeasuring changes in light as it is passed through the skull and surface of the brain•Electroencephalography (EEG) –a neuroimaging technique that measures electrical brainactivity via multiple electrodes on the scalp•Frontal lobe –the front most (anterior) part of the cerebrum; anterior to the central sulcus andresponsible for motor output and planning, language, judgment, and decision-making•Functional magnetic resonance imaging (fMRI) –neuroimaging technique that infers brainactivity by measuring changes in oxygen levels in the blood•Gray matter –the outer grayish regions of the brain comprised of the neurons’ cell bodies•Gyrus –fold between sulci in the cortex•Lateralized –“to the side”; used to refer to the fact that specific functions may reside primarilyin one hemisphere or the other•Lesion –a region in the brain that suffered damage through injury, disease, or medicalintervention
