Biologically Inspired Neural Architectures of Voluntary Movement1
Three novel brain-guided multi-modular neural network architectures are developed for the selection (decision making), generation and control of arm and ocular movements in normal and diseased brain states. The modules are developed using much of what is known about the human brain and its functional and modular decomposition. The models are: (1) Neural model of dopaminergic control of arm move...
متن کاملSex Differences in Electromechanical Delay during a Punch Movement1
—This study assessed how sex of participant is related to electromechanical delay during a karate punch. Ten male (M age = 25.00 yr., SD = 3.02; M height = 174.9 cm, SD = 6.3; M weight = 71.13 kg, SD = 9.35) and 8 female (M age = 27.4 yr., SD = 6.0; M height = 161.4 cm, SD = 5.1; M weight = 59.09 kg, SD = 7.00) karate athletes performed 10 ballistic punches to a target as hard as possible. Kine...
متن کاملInfluence of Host Chloroplast Proteins on Tobacco mosaic virus Accumulation and Intercellular Movement1[C][W][OA]
Tobacco mosaic virus (TMV) forms dense cytoplasmic bodies containing replication-associated proteins (virus replication complexes [VRCs]) upon infection. To identify host proteins that interact with individual viral components of VRCs or VRCs in toto, we isolated viral replicaseand VRC-enriched fractions from TMV-infected Nicotiana tabacum plants. Two host proteins in enriched fractions, ATP-sy...
متن کاملGene Silencing in Arabidopsis Spreads from the Root to the Shoot, through a Gating Barrier, by Template-Dependent, Nonvascular, Cell-to-Cell Movement1[W][OA]
Upward long-distance mobile silencing has been shown to be phloem mediated in several different solanaceous species. We show that the Arabidopsis (Arabidopsis thaliana) seedling grafting system and a counterpart inducible system generate upwardly spreading long-distance silencing that travels not in the phloem but by template-dependent reiterated short-distance cell-to-cell spread through the c...
متن کاملLectin-Mediated Resistance Impairs Plant Virus Infection at the Cellular Level C W OA
Plants possess a multilayered defense response, known as plant innate immunity, to infection by a wide variety of pathogens. Lectins, sugar binding proteins, play essential roles in the innate immunity of animal cells, but the role of lectins in plant defense is not clear. This study analyzed the resistance of certain Arabidopsis thaliana ecotypes to a potexvirus, plantago asiatica mosaic virus...
