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...

Frequency-band coupling in surface EEG reflects spiking activity in monkey visual cortex.

27 Oct 2009 Although the electroencephalogram (EEG) is widely used in research and clinical settings, its link to the underlying neural activity during sensory processing remains poorly understood. To investigate this, we made simultaneous recordings of surface ... Read more...
