Computer-assisted automatic localization of the human pedunculopontine nucleus in T1-weighted MR images: a preliminary study.

30 Aug 2009 BACKGROUND: The pedunculopontine nucleus (PPN) is a new promising target of deep brain stimulation (DBS) for the treatment of Parkinson's disease. This study was to develop a method of computer-assisted automatic localization of the PPN in ... Read more...

A simple model of cortical dynamics explains variability and state dependence of sensory responses in urethane-anesthetized auditory cortex.

24 Aug 2009 The responses of neocortical cells to sensory stimuli are variable and state dependent. It has been hypothesized that intrinsic cortical dynamics play an important role in trial-to-trial variability; the precise nature of this dependence, however, ... Read more...

GABAergic neuron distribution in the pedunculopontine nucleus defines functional subterritories.

30 Jul 2009 gamma-Aminobutyric acid (GABA)ergic neurons are widely distributed in brainstem structures involved in the regulation of the sleep-wake cycle, locomotion, and attention. These brainstem structures include the pedunculopontine nucleus (PPN), which is ... Read more...
