title: [Genes and the modulation of learning and memory].
abstract: Recently, progress in the study of the relationship between gene and the modulation of learning and memory was noticeable. The studies showed that: (1) The expression of immediate early genes (IEGs), especially the c-fos, is a necessary prerequisite for the formation of memory; the induction of long term potentiation (LTP) is accompanied by an increase of IEGs expression; (2) Mice with deficiency of alpha-Calcium-Calmodulin Kinase II (alpha-CaMK II), or neural-cell adhesion molecules (N-CAM) or tyrosine kinase gene (fyn) generated by gene targeting appear deficits in spatial learning and memory, mutation of alpha-CaMK II and N-CAM gene can also interfere with the induction and maintenance of LTP; (3) The single-gene mutants of Drosophilia (dnc, rut) showed significant decrease of the ability of memory. The mechanism is related to the altered synaptic plasticity, and the mushroom body may be the memory center of Drosophila.
