However, the mechanisms that underlie the behavioral changes induced by these abused drugs have not yet been elucidated. The present study was designed to investigate the mechanisms that underlie how abused drugs induce distinct behavioral changes using neurochemical as well as behavioral techniques in rats. Methamphetamine (2mg/kg) more potently increased dopamine release from the striatum more than that from the nucleus accumbens. In contrast, the administration of morphine (10mg/kg) produced a significant increase in the release of dopamine from the nucleus accumbens, but not the striatum, which is accompanied by a decrease in the release of GABA in the ventral tegmental area. These findings indicate that morphine and methamphetamine differentially regulate dopaminergic systems to produce behavioral changes, even though both drugs have abuse potential through activation of the mesolimbic dopaminergic system.","is_dataset_classified":null,"base_score":3.1780538303479458,"endowment":3.1780538303479458,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"26820597","pmcid":null,"openalex_id":"https://openalex.org/W2251367339","authors":[],"funders":[{"funder_name":"MEXT","grant_id":"S1411019","title":null}],"total_grants":1,"fwci":1.8556,"citation_percentile":0.83047079,"influential_citations":0,"citation_trend":[{"year":2016,"count":3},{"year":2017,"count":1},{"year":2018,"count":6},{"year":2019,"count":2},{"year":2020,"count":3},{"year":2021,"count":3},{"year":2022,"count":3},{"year":2024,"count":1},{"year":2026,"count":1}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0306452216000713?httpAccept=text/plain","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0306452216000713?httpAccept=text/xml","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.neuroscience.2016.01.043","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/26820597","host_type":"repository"}],"fields_of_study":["Neurotransmitter Receptor Influence on Behavior","Neuroscience and Neuropharmacology Research","Receptor Mechanisms and Signaling","Animals","Basal Ganglia","Catheters, Indwelling","Dopamine","Dopamine Agents","Male","Methamphetamine","Microdialysis","Morphine","Movement","Neurons","Rats, Sprague-Dawley","Real-Time Polymerase Chain Reaction","Ventral Tegmental Area","gamma-Aminobutyric Acid"],"mesh_terms":["Animals","Basal Ganglia","Catheters, Indwelling","Dopamine","gamma-Aminobutyric Acid","Male","Methamphetamine","Morphine","Movement","Neurons","Dopamine Agents","Rats, Sprague-Dawley","Microdialysis","Ventral Tegmental Area","Real-Time Polymerase Chain Reaction"],"keywords":["Nucleus accumbens","Ventral tegmental area","Dopaminergic","Mesolimbic pathway","Dopamine","Neurochemical","Methamphetamine","Striatum","Neuroscience","Basal ganglia","Ventral striatum","Olfactory tubercle","Microdialysis","Substantia nigra","Psychology","Reward system","Pharmacology","Medicine","Central nervous system","Morphine","GABA"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T04:21:37.102861Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
