==Early life== |
|||
Philip Seeman was born on February 8, 1934 in [[Winnipeg]], [[Manitoba]] and raised in [[Montreal]]. He received a [[Bachelor of Science]] degree, honours Physics & Physiology (1955), a [[Master of Science]] degree, Physiology of Transport & Secretion (1956), and a [[Doctor of Medicine]] (1960) from [[McGill University]]. Following McGill, Seeman took an internship at the Harper Hospital in Detroit, where he has stated he decided to go into medical research after seeing that the state of medicine at that time was unable to cure his patients sufficiently.<ref name=Shorter /> In 1966, he received a Ph.D. in Life Sciences from [[Rockefeller University]], and later pursued a post-doc at [[Cambridge University]].<ref name=NS>{{cite web|url=https://books.google.ca/books?id=d0hfAgAAQBAJ&pg=PA94|title=Psyche in the Lab|publisher=}}</ref><ref>{{cite web|url=http://sites.utoronto.ca/seeman/Philip_Seeman_lab/Welcome.html|title=DR.

In 2001, he was made an Officer of the [[Order of Canada]] "for his research on dopamine receptors and their involvement in diseases such as schizophrenia, Parkinson's and Huntington's".<ref>{{OCC|4875}}</ref> |
|||
In 1978, Seeman published findings in ''Nature'' that showed after an autopsy, the brains of schizophrenics have 50% or more dopamine receptors than the average human brain, though their research also pointed to the possibility that these additional receptors may have been caused by the medication the schizophrenic patients had been taking as treatment.<ref>{{cite web|url=https://books.google.ca/books?id=Z5IABAAAQBAJ&pg=PA101|title=Pharmacological Treatment of College Students with Psychological Problems|publisher=}}</ref> This led to further research that the medication itself was a cause for the increase of dopamine D2 receptors.<ref>{{cite web|url=https://books.google.ca/books?id=M-X1BgAAQBAJ&pg=PA20|title=The Science and Pseudoscience of Children's Mental Health: Cutting Edge ...|publisher=}}</ref> During the early 1980s, Seeman’s work was contrary to a prevailing idea that schizophrenia was a socially constructed disorder that could be cure through psychotherapy, with Seeman claiming that the source of the disorder was biological instead.<ref>{{cite web|url=https://news.google.com/newspapers?nid=1946&dat=19830903&id=dhUyAAAAIBAJ&sjid=SqUFAAAAIBAJ&pg=1378,936041&hl=en|title=The Montreal Gazette - Google News Archive Search|publisher=}}</ref><ref>{{cite web|url=https://news.google.com/newspapers?nid=1946&dat=19800902&id=uDMyAAAAIBAJ&sjid=qaQFAAAAIBAJ&pg=5613,91179&hl=en|title=The Montreal Gazette - Google News Archive Search|publisher=}}</ref> |

In 1989 Seeman discovered that endogenous neurotransmitters could displace receptor radioligands, for use in measuring the release of neurotransmitters during brain imaging. He then invented the radioactive PHNO to label D2High receptors in 1993.<ref name=Psych /> Seeman went on to research the efficacy of atypical antipsychotic drugs such as quetiapine, showing that they dissociated from the D2 receptor more quickly than prior drugs. His lab then hypothesized that those suffering from schizophrenia show an increase in the proportion of their D2 receptors in a state of high affinity for dopamine. He also published findings showing that narcotics such as amphetamines and ketamine cause a stimulation of D2 receptors that cause psychotic symptoms, including a higher causation in schizophrenic patients than the average person.<ref>{{cite web|url=http://www.medscape.com/viewarticle/547112|title=Medscape: Medscape Access|publisher=}}</ref> |

Seeman continued to pursue the research of how schizophrenia could be treated through drugs affecting the D2 receptor.<ref>{{cite web|url=https://books.google.ca/books?id=d0hfAgAAQBAJ&pg=PA97|title=Psyche in the Lab|publisher=}}</ref> In 2005 Seeman published that most psychotic-triggers, such as narcotics, gene mutations or lesions on the brain, cause an increase in D2High receptors and their resultant schizophrenic symptoms.<ref>{{cite web|url=https://books.google.ca/books?id=Cw6MlCXhN5MC&pg=PA296|title=Mad in America|publisher=}}</ref> Seeman also discovered that all anti-Parkinson’s disease drugs stmulate dopamine D2High receptors.<ref>{{cite web|url=http://www.thecanadianencyclopedia.ca/en/article/philip-seeman/|title=Philip Seeman|author=Rose Sheinin|work=The Canadian Encyclopedia}}</ref> |

Philip Seeman, OC FRSC (8 February 1934 – 9 January 2021) was a Canadian schizophrenia researcher and neuropharmacologist, known for his research on dopamine receptors.[1]
Career
[edit]Born in Winnipeg, Manitoba, Seeman was raised in Montreal. He received a Bachelor of Science degree, honours physics & physiology (1955), a Master of Science degree, physiology of transport & secretion (1956), and a Doctor of Medicine (1960) from McGill University. In 1966, he received a Ph.D. in life sciences from Rockefeller University under the supervision of George Emil Palade.[2]
In 1967, Seeman became an assistant professor in the Department of Pharmacology at the University of Toronto. In 1970, he was appointed a professor.
In 1974, having spent years in search of the binding site of antipsychotic medication, he discovered the dopamine D2 receptor, the basis for the dopamine hypothesis of schizophrenia.[3][4] His discoveries also helped advance research on other diseases involving dopamine, such as Parkinson's disease and Huntington's disease.[2]
In 2001, he was made an Officer of the Order of Canada "for his research on dopamine receptors and their involvement in diseases such as schizophrenia, Parkinson's and Huntington's".[5]
In 1985, he was made a Fellow of the Royal Society of Canada.[6]
He was married to Dr. Mary V. Seeman.[7]
