default mode network? IS INVOLVED IN REPROCESSING PREVIOUSLY EXPERIENCED
STIMULI The most likely reason that adults are superior to adolescents in abstract thinking. The brain
undergoes: SYNAPTIC PRUNING Dorsal-lateral-pre-frontal cortext plays important role in what
activity? WORKING MEMORY Drug abuse activates neuro circuits. Generates signals in the ventral
tegmental area and to where? DOPAMINE INTO THE NUCLEUS ACCUMBENS Ninety-five percent
of righthanded people develop left hemispheric dominance for language. What percentage of left
handed people develop left hemispheric dominance for language? 75% Prostaglandin D2 increases
extracellular levels of... ADENOSINE Which is a retrograde neurotransmitter?
ENDOCANNABINOIDS Characteristics of Ach receptors in cerebral cortex BOTH INHIBITORY
AND EXCITATORY Neurohormone for social bonding OXYTOCIN 28 y. o. hospitalized with
paranoid delusions, AH, and agitation, tx w/Haldol 5, pt becomes rigid & mute, in days gets
choreoform mvmt, has seizures, gets resp problems leading to ICU admit. Exam shows ovarian mass,
