Monopolar mapping of motor function differs from the most commonly used method of intraoperative mapping, i.e. bipolar direct electrical stimulation at 50-60Hz (Penfield technique mapping). Most importantly, the monopolar probe emits a radial, homogenous electrical field different to the more focused inter-tip bipolar electrical field.

Human Movement Science, 2005
Consider the process of raising and lowering the arm in the sagittal plane. Different parts of different muscles operate over different sectors of the angular range. How and why does the nervous system implement this differential muscle activation according to joint angle?

Neurosurgery Clinics of North America, 2011
Functional magnetic resonance imaging (fMRI) enhances the understanding of neuroanatomy and functions of the brain and is becoming an accepted brain-mapping tool for clinicians, researchers, and basic scientists alike. A noninvasive procedure with no known risks, fMRI has an ever-growing list of clinical applications, including presurgical mapping of ...

MAPs and motors in insect ovaries
Journal of Cell Science, 1991ABSTRACT MAPs and microtubule motor proteins from the massive microtubule translocation complexes within the ovaries of hemipteran insects have been identified and characterized. Both classes of proteins have been compared with those of other systems, and the function of both in the insect ovaries is speculated upon.

Chaos control by using Motor Maps
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2002In this paper a new method for chaos control is proposed, consisting of an unsupervised neural network, namely a Motor Map. In particular a feedback entrainment scheme is adopted: a chaotic system with a given parameter set generates the reference trajectory for another chaotic system with different parameters to be controlled: the Motor Map is ...

Microtubules, MAPs, and motor patterns
2015Cells have an amazing ability to self-organize and rearrange their interiors. Such morphology changes are essential to cell development, division, and motility. The core of a cell's internal organization lies with the cytoskeleton made of both microtubule and actin filaments with their associated proteins and ATP-utilizing enzymes.

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.

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.

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 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.
