Studies in avian carbohydrate metabolism

IT is characteristic of the pigeon's brain that the rate of respiration falls very rapidly during survival in Ringer-phosphate solution. The addition of glucose [Gavrilescu and Peters, 1931] and more so of lactate [Gavrilescu et al., 1932] increases the uptake over periods of an hour; even in this case the maintenance of respiration claimed by a series of workers for mammalian brain is not seen [cf.
