1. Left dominance for language perception starts in the extrastriate cortex: An ERP and sLORETA study.

    Behavioural Brain Research 291:325 (2015) PMID 26048428

    While it is well known that the left hemisphere is more efficient than the right in most tasks involving perception of speech stimuli, the neurophysiological pathways leading to these lateralised performance differences are as yet rather unclear. In particular, the question whether language late...
  2. Electrophysiological mismatch response recorded in awake pigeons from the avian functional equivalent of the primary auditory cortex.

    Neuroreport 26(5):239 (2015) PMID 25646582

    The neural response to occasional variations in acoustic stimuli in a regular sequence of sounds generates an N-methyl-D-aspartate receptor-modulated event-related potential in primates and rodents in the primary auditory cortex known as mismatch negativity (MMN). The current study investigated ...

  4. The metabotropic glutamate receptor, mGlu5, is required for extinction learning that occurs in the absence of a context change.

    Hippocampus 25(2):149 (2015) PMID 25160592 PMCID PMC4322473

    The metabotropic glutamate (mGlu) receptors and, in particular, mGlu5 are crucially involved in multiple forms of synaptic plasticity that are believed to underlie explicit memory. MGlu5 is also required for information transfer through neuronal oscillations and for spatial memory. Furthermore, ...

  9. Handedness and the X chromosome: The role of androgen receptor CAG-repeat length.

    Scientific reports 5:8325 (2015) PMID 25659367 PMCID PMC4321186

    Prenatal androgen exposure has been suggested to be one of the factors influencing handedness, making the androgen receptor gene (AR) a likely candidate gene for individual differences in handedness. Here, we examined the relationship between the length of the CAG-repeat in AR and different hand...
  10. Noradrenergic stimulation modulates activation of extinction-related brain regions and enhances contextual extinction learning without affecting renewal.

    Frontiers in Behavioral Neuroscience 9:34 (2015) PMID 25745389 PMCID PMC4333811

    Renewal in extinction learning describes the recovery of an extinguished response if the extinction context differs from the context present during acquisition and recall. Attention may have a role in contextual modulation of behavior and contribute to the renewal effect, while noradrenaline (NA...

  12. Perceptual strategies of pigeons to detect a rotational centre-a hint for star compass learning?

    PLoS ONE 10(3):e0119919 (2015) PMID 25807499 PMCID PMC4373800

    Birds can rely on a variety of cues for orientation during migration and homing. Celestial rotation provides the key information for the development of a functioning star and/or sun compass. This celestial compass seems to be the primary reference for calibrating the other orientation systems in...

  16. Blocking NMDA-receptors in the pigeon's "prefrontal" caudal nidopallium impairs appetitive extinction learning in a sign-tracking paradigm.

    Frontiers in Behavioral Neuroscience 9:85 (2015) PMID 25918502

    Extinction learning provides the ability to flexibly adapt to new contingencies by learning to inhibit previously acquired associations in a context-dependent manner. The neural networks underlying extinction learning were mostly studied in rodents using fear extinction paradigms. To uncover inv...

  20. Evidence for interhemispheric conflict during meta-control in pigeons.

    Behavioural Brain Research 270:146 (2014) PMID 24844753

    In birds each hemisphere receives visual input from the contralateral eye. Since birds have no corpus callosum, avian brains are often seen as 'natural split brains'. How do birds cope with situations, when both hemispheres are brought into conflict? If under such conditions one hemisphere compl...
