Correlating stimulus-specific adaptation of cortical neurons and local field potentials in the awake rat.

2 Nov 2009 Changes in the sensory environment are good indicators for behaviorally relevant events and strong triggers for the reallocation of attention. In the auditory domain, violations of a pattern of repetitive stimuli precipitate in the event-related ... 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...

Cortical deactivation induced by subcortical network dysfunction in limbic seizures.

12 Oct 2009 Normal human consciousness may be impaired by two possible routes: direct reduced function in widespread cortical regions or indirect disruption of subcortical activating systems. The route through which temporal lobe limbic seizures impair ... Read more...
