Resolving response, decision, and strategic control: evidence for a functional topography in dorsomedial prefrontal cortex.

19 Oct 2009 The dorsomedial prefrontal cortex (DMPFC) plays a central role in aspects of cognitive control and decision making. Here, we provide evidence for an anterior-to-posterior topography within the DMPFC using tasks that evoke three distinct forms of ...

Spatiotemporal distortions of visual perception at the time of saccades.

19 Oct 2009 Both space and time are grossly distorted during saccades. Here we show that the two distortions are strongly linked, and that both could be a consequence of the transient remapping mechanisms that affect visual neurons perisaccadically. We measured ...

Analgesia accompanying food consumption requires ingestion of hedonic foods.

12 Oct 2009 Animals eat rather than react to moderate pain. Here, we examined the behavioral, hedonic, and neural requirements for ingestion analgesia in ad libitum fed rats. Noxious heat-evoked withdrawals were similarly suppressed during self-initiated ...

Cerebellar contributions to adaptive control of saccades in humans.

12 Oct 2009 The cerebellum may monitor motor commands and through internal feedback correct for anticipated errors. Saccades provide a test of this idea because these movements are completed too quickly for sensory feedback to be useful. Earlier, we reported ...

Inhibitor kappaB Kinase beta deficiency in primary nociceptive neurons increases TRP channel sensitivity.

12 Oct 2009 Inhibitor kappaB kinase (IKK) regulates the activity of the transcription factor nuclear factor-kappa B that normally protects neurons against excitotoxicity. Constitutively active IKK is enriched at axon initial segments and nodes of Ranvier (NR). ...

Convergence of cranial visceral afferents within the solitary tract nucleus.

12 Oct 2009 Primary afferent axons within the solitary tract (ST) relay homeostatic information via glutamatergic synapses directly to second-order neurons within the nucleus of the solitary tract (NTS). These primary afferents arise from multiple organ systems ...

Involvement of the thalamocortical loop in the spontaneous switching of percepts in auditory streaming.

5 Oct 2009 Perceptual grouping of successive frequency components, namely, auditory streaming, is essential for auditory scene analysis. Prolonged listening to an unchanging triplet-tone sequence produces a series of illusory switches between a single coherent ...

The maturation of task set-related activation supports late developmental improvements in inhibitory control.

5 Oct 2009 The ability to voluntarily inhibit a single response is evident early in development, even as the ability to maintain an inhibitory "task set" continues to improve. To date, functional neuroimaging studies have detailed developmental changes in ...

Driving under low-contrast visibility conditions in Parkinson disease.

4 Oct 2009 OBJECTIVE: To assess driving performance in Parkinson disease (PD) under low-contrast visibility conditions. METHODS: Licensed, active drivers with mild to moderate PD (n = 67, aged 66.2 +/- 9.0 years, median Hoehn-Yahr stage = 2) and controls (n = ...

Effects of alcohol and sleep restriction on simulated driving performance in untreated patients with obstructive sleep apnea.

4 Oct 2009 BACKGROUND: Because of previous sleep disturbance and sleep hypoxia, patients with obstructive sleep apnea (OSA) might be more vulnerable to the effects of alcohol and sleep restriction than healthy persons. OBJECTIVE: To compare the effects of ...
