Dynamic encoding of movement direction in motor cortical neurons.

2 Nov 2009 When we perform a skilled movement such as reaching for an object, we can make use of prior information, for example about the location of the object in space. This helps us to prepare the movement, and we gain improved accuracy and speed during ... Read more...

Functional clustering of neurons in motor cortex determined by cellular resolution imaging in awake behaving mice.

2 Nov 2009 Macroscopic (millimeter scale) functional clustering is a hallmark characteristic of motor cortex spatial organization in awake behaving mammals; however, almost no information is known about the functional micro-organization (approximately 100 ... Read more...

The differential role of motor cortex in stretch reflex modulation induced by changes in environmental mechanics and verbal instruction.

19 Oct 2009 The motor cortex assumes an increasingly important role in higher mammals relative to that in lower mammals. This is true to such an extent that the human motor cortex is deeply involved in reflex regulation and it is common to speak of ... Read more...
