[The mechanisms of the integrative activity of neurons]

Modern state of neuron integrative activity problem was considered at the base of data analysis received during investigations of simple learning forms in molluscs and long-term potentiation in mammalians. Experimental data shown that different forms of synaptic plasticity which have been characterized by common or particular features of molecular providing involved in integrative activity of various kinds of nervous cells during some forms of learning. Mechanisms of postsynaptic messengment convergated to exiting neurons and there molecular transformation in cytoplasm and nuclei were discussed. Hypothesis of long-term synaptic plastic transformation and detention mechanisms in snail neurons during associative learning was suggested.
