Deep-body thermosensitivity: Another look. A tribute to Harold Theodore (Ted) Hammel (1921-2005)

Experimental analysis of deep-body thermoreception in 1912 put forward the thesis of hypothalamic thermoregulation, whereas experiments in 1935 suggested, as an antithesis, distributed central nervous thermoreception. The high/low Q sub(10) concept of hypothalamic thermoreception and the discovery of spinal deep-body thermoreception, both published first in 1963, raised thesis and antithesis to new levels. Common work of the respective proponents, Hammel and the author, disclosed inter-class differences in deep-body thermosensor distribution between mammals and birds in 1975. Subsequent research has established, as the synthesis, the current concept of deep-body temperature control by partially independent, multiple input-output-effector loops.
