Information processing in brain microtubules.
Models of the mind are based on the idea that neuron microtubules can perform computation. From this point of view, information processing is the fundamental issue for understanding the brain mechanisms that produce consciousness. The cytoskeleton polymers could store and process information through their dynamic coupling mediated by mechanical energy. We analyze the problem of information tran...
متن کاملMechanical properties of brain tubulin and microtubules
We measured the elasticity and viscosity of brain tubulin solutions under various conditions with a cone and plate rheometer using both oscillatory and steady shearing modes. Microtubules composed of purified tubulin, purified tubulin with taxol and 3x cycled microtubule protein from pig, cow, and chicken behaved as mechanically indistinguishable viscoelastic materials. Microtubules composed of...
متن کاملLIS1 and DCX: Implications for Brain Development and Human Disease in Relation to Microtubules
Proper lamination of the cerebral cortex requires the orchestrated motility of neurons from their place of birth to their final destination. Improper neuronal migration may result in a wide range of diseases, including brain malformations, such as lissencephaly, mental retardation, schizophrenia, and autism. Ours and other studies have implicated that microtubules and microtubule-associated pro...
متن کاملMicrotubules in dendritic spine development.
It is generally believed that only the actin cytoskeleton resides in dendritic spines and controls spine morphology and plasticity. Here, we report that microtubules (MTs) are present in spines and that shRNA knockdown of the MT plus-end-binding protein EB3 significantly reduces spine formation. Furthermore, stabilization and inhibition of MTs by low doses of taxol and nocodazole enhance and im...
متن کاملMicrotubules in Dendritic Spine Development and Plasticity.
Recent studies indicate that microtubules (MTs) may play an important role in spine development and dynamics. Several imaging studies have now documented the exploration of dendritic spines by dynamic MTs in an activity-dependent manner. Furthermore, it was found that alterations of MT dynamics by pharmacological and molecular approaches exert profound influence on the development and plasticit...
