Interaction of kinesin motors, microtubules, and MAPs
Journal of Muscle Research and Cell Motility, 2005Kinesins are a family of microtubule-dependent motor proteins that carry cargoes such as vesicles, organelles, or protein complexes along microtubules. Here we summarize structural studies of the "conventional" motor protein kinesin-1 and its interactions with microtubules, as determined by X-ray crystallography and cryo-electron microscopy.

Noninvasive mapping of human motor cortex
Neurology, 1988Human motor cortex was stimulated using brief, high-voltage electrical stimulation. Constant-voltage stimuli were delivered through a bipolar surface stimulator with the anode placed at multiple positions on the scalp and the cathode situated 2.5 cm anterior to the anode.

Motor mapping in cerebral palsy
Developmental Medicine & Child Neurology, 2009The measurement of motor deficits in individuals with cerebral palsy (CP) has been largely based on clinical criteria. Yet functional imaging and non‐invasive stimulation methods provide a means to measure directly abnormalities of the motor system.

Motor maps and the cortical control of movement
Current Opinion in Neurobiology, 2014The brain's cortical maps serve as a macroscopic framework upon which additional levels of detail can be overlaid. Unlike sensory maps generated by measuring the brain's responses to incoming stimuli, motor maps are made by directly stimulating the brain itself.

Dynamic features of sensory and motor maps
Current Opinion in Neurobiology, 1992Recent data support the idea that the functional organizations of sensory and motor maps in the mature brain are dynamically maintained. Experiments employing peripheral injuries or other manipulations indicate that these maps are capable of extensive reorganization.

Neurosurgery must always carefully balance the benefit of surgical therapy against the risk of causing or increasing neurological symptoms. Preoperative risk assessment on the basis of standard anatomical imaging alone is often insufficient because of inherent variations in motor representation from one patient to the next and because pathology can ...

In Search of the Motor Engram: Motor Map Plasticity as a Mechanism for Encoding Motor Experience
The Neuroscientist, 2005Motor skill acquisition occurs through modification and organization of muscle synergies into effective movement sequences. The learning process is reflected neurophysiologically as a reorganization of movement representations within the primary motor cortex, suggesting that the motor map is a motor engram.

The output map of the primate motor cortex
Trends in Neurosciences, 1988Abstract What is ‘represented' in the primate motor cortex? Most approaches have defined the output map of the cortex rather than giving any clear answers as to functional representation. This results in part from the artificial nature of the electrical stimuli used to map the outputs.

Cortical maps for motor planning
[Proceedings] 1992 RNNS/IEEE Symposium on Neuroinformatics and Neurocomputers, 1992A distributed computational architecture for the motor planning functions is explored. It combines a paradigm of self-organization (for building robust and coherent maps of the different motor spaces) with relaxation dynamics (for run-time incorporation of task constraints).

Computing the motor-sensor map
Behavioral and Brain Sciences, 2004“Articulate models” subservient to formal intelligence are imagined to be heterarchies of automata capable of performing the “symbolic (quasi-spatial) syntheses” of Luria (1973), where “quasi-spatial” points to the abstract core of spatiality: the symbol productions, combinations, and substitutions of algebraic reckoning.
