Reduction of the postexcitatory cortical inhibition upon paired-click auditory stimulation in patients with Parkinson's disease.

17 Sep 2009 OBJECTIVES: The aims of this study were: to investigate the postexcitatory inhibition of cortical evoked potentials on auditory paired-click stimulation in patients with Parkinson's disease (PD), to analyze the correlation of N1-P2 amplitude ratios ... 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...

GABA shapes selectivity for the rate and direction of frequency-modulated sweeps in the auditory cortex.

22 Jun 2009 In the pallid bat auditory cortex and inferior colliculus (IC), the majority of neurons tuned in the echolocation range is selective for the direction and rate of frequency-modulated (FM) sweeps used in echolocation. Such selectivity is shaped ... Read more...
