Produktbeschreibung
Excerpt from The Journal of Nervous and Mental Disease, 1919, Vol. 49 Usually such bird live only a short time, a few days or weeks, in marked contrast cerebrate birds with thalamus intact in which, the bird, with proper care may live for months. Various attempts have been made to explain these differences, the usual statements implying that the reflex pathways involve this part of the brain, or are in some way dependent on it. The loss of the thalamus produces effects which in some ways resemble those attributed to shock. Bechterew considered that the thalamic part of the brain must bear some direct relation to the normal functioning of the visceral organs. Various things suggested a study of the body temperature in these birds with rather surprising results. The facts are indicated by the accompanying graph. It was found that the decerebrate bird with thalamus intact maintained normal body temperature through extreme ranges of temperature of its cage of from - 4 to 36 degrees C. But in the bird in which the thalamus is removed, the temperature fluctuates with that of its cage. It does not become identical with that of the environment but averages 8 to 10 degrees above it.
