Demetrius the Chronographer and 141 BCE

We only have six fragments from a book written by Demetrius the Chronographer. Scholars claim he lived and worked in Alexandria about 225-200 BCE and he is an early witness for the date of the LXX. However, the few chronological details we have indicate that he used the year 141 BCE as the base year for his chronology. There are no early witnesses for the LXX and there are no reliable obstacles for lowering the date for the LXX to 130 B.C. or even lower.     

Historical Development of the Dopamine Hypothesis of Schizophrenia

This review examines the history of discoveries that contributed to development of the dopamine hypothesis of schizophrenia. The origin of the hypothesis is traced to the recognition that neuroleptic drugs interfere with brain dopamine function. This insight was derived from two distinct lines of research. The first line originated from the discovery in 1956 that reserpine depletes brain serotonin. This finding resulted in a sequence of studies that led to the discovery that brain dopamine is involved in neuroleptic-induced extrapyramidal motor disturbances. The second line of research was aimed at determining the mechanism of action of psychomotor stimulants. This research produced evidence that stimulants directly or indirectly activate brain dopamine receptors. Because nonreserpine neuroleptics such as chlorpromazine block stimulant-induced movement, these findings suggested that neuroleptics were dopamine antagonists. Most previous accounts of the development of the dopamine hypothesis of schizophrenia emphasize the first line of research and ignore the second.     

The Myth of Reserpine-Induced Depression: Role in the Historical Development of the Monoamine Hypothesis

For five decades it has been generally accepted that reserpine, an antihypertensive and antipsychotic drug, causes depression. The discovery that reserpine depletes brain monoamines was an important factor in the development of the monoamine hypothesis of depression, and it continues to be widely cited in support of this hypothesis. The present paper argues that, contrary to prevailing belief, reserpine is not depressogenic. The reason for perpetuation of this myth is reluctance to discard the monoamine hypothesis. This hypothesis ushered the modern biochemical paradigm into psychiatry and is still of great importance. It serves as a heuristic to guide research, it enhances psychiatry’s prestige, and it helps to validate and promote drug therapy for depression and other mental disorders.
