WorksheetsBIOPSYCHOLOGY Pleasure Centers of the Brain
Total questions: 10
Worksheet time: 5mins
The most compelling studies locating the pleasure centers of the brain is related to
Sleep Deprivation
Circadian Rhythm
Intracranial Self-Stimulation
Olfactory Sensation
The experiments that generally explore the reward circuits of the brain began by studying rats which are hooked-up with electrodes connected to the lateral hypothalamus. In particular, rat behaved by
exhibiting anxiety when removed from the ocean
exhibiting greater amount of sleep
exhibiting rapid food intake
exhibiting compulsive lever pressing
Collectively the reward circuits of the brain is grouped into __ dopamine system
tuberoinfundibular
mesotelencephalic
craniovestibular
anterosagital
The two midbrain nuclei involved in rewards circuits are in the brain stem particularly the nuclei from
corpus callosum and reticular formation
olfactory bulb and optic chiasm
substancia nigra and ventral tegmental area
frontal lobe and parietal lobe
Aside from the nigrostriatal dopaminergic system another pathway theorized to be one of the reward circuits of the brain is the
mesocorticolimbic pathway
spinothalamic pathway
dorsal column medial lemniscus system
spinoreticulolimbic pathway
One of the main substance thought to mediate pleasure in the brain is
acetylcholine
guanine
dopamine
thymine
which is not true?
addiction experiments is done mostly using animals
drug addiction is an adaptive behavior
addiction research should center on the mesocorticolimbic pathway
drug addiction is a non adaptive behavior
one of the paradigms used in studying drug addiction is
drug awareness paradigm
drug self-administration paradigm
drug withdrawal paradigm
drug war paradigm
in condition place-preference paradigm, rats
prefer to go to a compartment associated with pleasure drug
prefer injections in the head rather than in stomach
prefer drugs associated with their natural habitat
prefer food found in their home
A nucleus in the brain associated with dopamine induced pleasure is the
amacrine nucleus
putamen
nucleus acumbens
pontine nucleus
