Using a name-based categorization task, Nazzi found in 2005 that French-learning 20-month-olds can make use of one-feature consonantal contrasts between new labels but fail to do so with one-feature vocalic contrasts. This asymmetry was interpreted as developmental evidence for the proposal that consonants play a more important role than vowels at the(More)
Double-label immunohistochemistry was employed to establish whether immunoreactivity for the beta subtype of the oestrogen receptor (ER beta-IR) is present in gonadotropin releasing hormone (GnRH)-containing cells. In the immortalized GnRH cell line, GT1-7, almost all nuclei were immunoreactive for ER beta. In the preoptic area of ovariectomized rats, more(More)
Recent data suggest that the first presentation of a foreign accent triggers a delay in word identification, followed by a subsequent adaptation. This study examines under what conditions the delay resumes to baseline level. The delay will be experimentally induced by the presentation of sentences spoken to listeners in a foreign or a regional accent as(More)
The recognition of familiar words was evaluated in 20-month-old children raised in a rhotic accent environment to parents that had either rhotic or non-rhotic accents. Using an Intermodal Preferential Looking task children were presented with familiar objects (e.g. 'bird') named in their rhotic or non-rhotic form. Children were only able to identify(More)
The effects of chronic administration of electroconvulsive shock and antidepressant drugs on rat brain serotonin-2 (5-HT2) receptors were investigated. Electroconvulsive shock increases the density and antidepressant drugs decrease the density of 5-HT2 receptors labelled by [3H]spiperone.
Having used the cingulate cortex to demonstrate the validity of our methods for detecting hitherto unrecognized oestrogen receptor alpha (ERalpha)-immunoreactive neurones, we have now employed immunoprecipitation and double-label immunohistochemistry to investigate whether the ERalpha protein is present in gonadotrophin-releasing hormone (GnRH)-containing(More)
We address the problem of directable weathering of exposed concave rock for use in computer-generated animation or games. Previous weathering models that admit concave surfaces are computationally inefficient and difficult to control. In nature, the spheroidal and cavernous weathering rates depend on the surface curvature. Spheroidal weathering is fastest(More)
The presence of oestrogen receptor alpha (ERalpha)-immunoreactivity (IR) in the cerebral cortex of adult rats has been investigated. Previous studies have reported a negligible presence of ERalpha or ERalpha mRNA in this region of the adult rat brain. We have used immunoprecipitation and immunohistochemistry, with various antibodies and fixatives, to detect(More)
