Actin Matrix of Dendritic Spines, Synaptic Plasticity, and Long-Term Potentiation

摘要: Publisher Summary This chapter describes the composition of spine cytoplasm along with synaptic activity generated by spine. Dendritic spines are appendage-like outgrowths dendrites. They contain an enlarged terminal part (the head) and a slender stalk connecting head parent dendrite. A small protrusion emanating from into axon contacting dendritic is termed as “spinule.” endowed considerable degree plasticity because they readily modified stimulation changes in environment. Synaptic considered one most important properties brain it allows for adaptive response to past events experiences. The apparatus (SA) consists parallel membranous sacs that alternate plates dense material, which contacted microtubules during development. SA continuity smooth endoplasmic reticulum (SER) absence cytoplasmic organelles full use actin cytomatrix, particularly dense. Out entire neuron, highest density filaments, arranged such way determine characteristic shape
