Memory-like effects in brain reward pathway could contribute to drug addiction. The effects of nicotine upon brain regions involved in addiction mirror those of cocaine, according to new neuroscience research. A single 15-minute exposure to nicotine caused a long-term increase in the excitability of neurons involved in reward, according to a study published in The Journal of Neuroscience.
But it is only in the last several decades that nicotineâs mechanism of action in the brain has been revealed. Nicotine works primarily by upregulating nicotinic acetylcholine receptors (nAChR) in the brain. Increasing neural signaling of neurotransmitters and boosting alertness, cognition and memory.
