Both [1- 14C]glucose and 2-[1- 14C]deoxyglucose produce selective iso-frequency labelling in the inferior colliculus of the cat with short stimulation periods

Both [1- 14C]glucose and 2-[1- 14C]deoxyglucose (2-DG) revealed selective autoradiographic labelling to tones in the inferior colliculus of the cat with short stimulation periods (5–15 min). With longer periods of stimulation (45 min), the selectivity disappeared with glucose but remained with 2-DG....

description Both [1- 14C]glucose and 2-[1- 14C]deoxyglucose (2-DG) revealed selective autoradiographic labelling to tones in the inferior colliculus of the cat with short stimulation periods (5–15 min). With longer periods of stimulation (45 min), the selectivity disappeared with glucose but remained with 2-DG. At all stimulation intervals, 2-DG labelling was always more selective than that obtained with glucose. However, the selectivity seen with glucose was good enough to indicate that isotopes of glucose with short half-lives could still be employed to study human functional activity with the positron emission tomography technique, provided that short stimulation periods were used.
