Changing meaning causes coupling changes within higher levels of the cortical hierarchy
tkoie 2009/06/25
the manner in which bilateral primary auditory cortex interact during speech and nonspeech processing is not well understood. --- we show a dissociation in neuronal interactions, occurring at both different hierarchal levels of the auditory system and in different hemispheres.

Medial temporal theta state before an event predicts episodic encoding success in humans
tkoie 2009/03/31
We report a human electrophysiological brain state that predicts successful memory for events before they occur. Using magnetoencephalographic recordings of brain activity during episodic memory encoding, we show that amplitudes of theta oscillations shortly preceding the onsets of words were higher
