Roland L. Fischer

Roland L. Fischer (1915 in Budapest , Hungary – 1997 in Majorca , Spain [1] ) was an experimental psychiatrist and psychopharmacologist known for his early work on schizophrenia, the perception-hallucination continuum model of altered states of consciousness , and for his work one tasting qui later Contributed to research Supporting supertasting . [2] : 226 [3] : 9 [4] Fischer was formerly professor of experimental psychiatry and associate professor of pharmacology at Ohio State University (1958-1971),[5] and also held academic posts at George Washington University, Georgetown, and Johns Hopkins University. [6] : 13, 259-260

Life and career

Fischer was born in Budapest in 1915. Six months before the start of World War II in 1939, Fischer left Hungary to study chemistry at the University of Basel in Switzerland , where he received his Ph.D. in 1945. [5] [7 ] Fischer Was active entre 1951 and 1977 and Was the author of more than 350 publications. [6] : 259 [8] In the 1970s, Fischer was a lecturer in pharmacology at the George Washington University Medical School and the Johns Hopkins Medical School and an editor for the Journal of Altered States of Consciousness. At this time, his interests involved biofeedback and EEG research on different states of consciousness. [7] In 1977, he retired to the island of Majorca where he died in 1997. In gratitude for the opportunities for engaging in teaching and research offered by the University of the Balearic Islands, he donated his personal collection of books to the library of the University of the Balearic Islands. [1] [9]

Model psychosis hypothesis

See also: LSD and schizophrenia

Like German chemist Kurt Beringer (1893-1949) before him, Fischer began to look for an explanatory model of psychosis for schizophrenia in the late 1940s by comparing it to altered states produced by hallucinogens. [10] : 226 In the 1950s, Fischer studied schizophrenia as a research biochemist at the University of Saskatchewan. [11] Fischer explored the hypothetical model of hypothesis of altered drug states by Beringer in 1927. Fischer and other researchers wondered if LSD could act as a chemical model for schizophrenia . However, both biochemical research progressed over time and the evidence of both substance-induced psychosisand organic psychosis are remarkably different.

Taste science

In the 1960s, he is a proponent of the relationship between prop (6- n -propylthiouracil) and food relations, and its relationship to alcohol use and smoking. [12] His early work in science contributed to later research on supertasting. [13]

Perception-hallucination continuum

Between 1968 and the late 1980s, Fischer developed a model for altered states of consciousness in several stages known as the perception-hallucination continuum. On the continuum were ecstatic states , such as mystical rapture , separated by hyperaroused and hallucinatory states that schizophrenics might experience, followed by an aroused state, such as during creativity . Normal consciousness resides in the middle of the continuum. On the other end are the hypoaroused states, Such As Those Experienced During samadhi , separated by tranquil states, for example During Zen Meditation . [14] [15] [16]
