In this article, the role of cholinergic, dopaminergic, adrenergic, serotoninergic and gabaergic neurotransmitters in cognitive behavior is reviewed. Method: This is a review article. Results & Conclusion: The involvement of cholinegric system in memory and pathological states such as dementia, is a replicated finding. However, the function of this system cannot completely explain the cognitive processes of learning and memory. Several animal studies have explored the role of different neurotransmitter systems on learning and memory. Any decrease or increase in levels of the neurotransmitters or activation or blockade of relevant receptors may alter learning and memory. It seems that a network consisting of different neurotransmitter systems may be important for learning and memory processing. }, URL = {http://icssjournal.ir/article-1-278-en.html}, eprint = {http://icssjournal.ir/article-1-278-en.pdf}, journal = {Advances in Cognitive Sciences}, doi = {}, year = {2003} }
