Brain metabolic effects of acute nicotine. Academic Article uri icon

abstract

  • Nicotine acetylcholine receptors are located on both nerve cell bodies and synaptic terminals, are permeable to calcium, and function perhaps predominantly by facilitating the release of neurotransmitters and neuropeptides. The behavioral rewards from (−) nicotine and perhaps addiction appear to be related to dopamine release. 31 P NMR analysis reveals subcutaneously administered (−) nicotine produces acute alterations in brain membrane phospholipid and high-energy phosphate metabolism of Fischer 344 rats. These metabolic responses to (−) nicotine could contribute to nicotine's behavioral effects.
