A growing body of evidence suggests that an interference with dopamine (DA) transmission disrupts maternal behavior in the rat. The present brain microdialysis study was therefore conducted to investigate whether infants can modulate ventral striatal DA release in mother rats. There was a significant rise in the extracellular concentrations DA,(More)
The present experiments characterized the impairment in pup retrieval previously observed in maternal rats following dopamine-depleting 6-hydroxydopamine (6-OHDA) infusions in the ventral striatum. Video recordings of 30-min pup retrieval tests revealed that 6-OHDA mothers spent most of the time feeding (Experiment 1). Denying the mothers the opportunity to(More)
BACKGROUND Mild cognitive impairment (MCI) has been considered a transitional state between normal aging and dementia, characterised by memory impairment but normal general cognitive functioning. Recently other cognitive deficits have been reported. This has led to a modification of MCI criteria. OBJECTIVE To examine which neuropsychological tests most(More)
The present study assessed neuropsychological functions related to attention, executive function and everyday memory in a group of men with a diagnosis of combat-related posttraumatic stress disorder (PTSD). Twenty Bosnian male combat veterans with a diagnosis of PTSD were tested using the Sustained Attention to Response Task, the Hayling Sentence(More)
The Empathy- and Systemizing Quotients (EQ and SQ, respectively; Baron-Cohen, 2003) were determined in a Swedish sample consisting mainly of university undergraduates. Females had significantly higher EQ than males, who in turn scored higher on the SQ inventory. Gender explained 12-14% of the variation. Males were strikingly overrepresented in the group(More)
Female rats with continuous access to water and 6% ethanol were given bilateral ventral striatal 6-OHDA infusions, which induced pronounced striatal depletions of dopamine. The postoperative ethanol consumption of these rats was not significantly affected in comparison to vehicle-infused controls. In a second experiment, female rats received escalating(More)
OBJECTIVE To investigate the ability of patients with myotonic dystrophy type 1 to recognise basic facial emotions. We also explored the relationship between facial emotion recognition, neuropsychological data, personality, and CTG repeat expansion data in the DM-1 group. METHODS In total, 50 patients with DM-1 (28 women and 22 men) participated, with 41(More)
This paper introduces a framework for route directions based on research results from cognitive science. Contrary to existing route planning systems this approach focuses on cognitive aspects to improve the communication of route knowledge. In order to achieve cognitively adequate communication we need to (a) organise data according to the cognitive model(More)
The affective mimetic responses of male Wistar rats with prior access to 6% ethanol in their home cages were observed during intraoral infusions of an equivalent alcohol solution. Ethanol preference in the home cage appeared unrelated to measures of aversion and ingestion in the taste reactivity tests in normal rats. Adrenalectomy, which significantly(More)
The cochlear implant (CI) involves the introduction of alloplastic materials into the cochlea. While current implants interact with cochlear neurons at a distance, direct interactions between spiral ganglion (SG) neurites and implants could be fostered by appropriate treatment with neurotrophic factors. The interactions of fibroblasts and osteoblasts with(More)
