The strongest sex differences on any cognitive task, favoring men, are found for tasks that require the mental rotation of three-dimensional objects. A number of studies have explored functional brain activation during mental rotation tasks, and sex differences have been noted in some. However, in these studies there was a substantial confounding factor(More)
BACKGROUND Negative symptoms may be associated with dysfunction of the brain reward system in schizophrenia. We used functional magnetic resonance imaging (fMRI) to assess the BOLD response in the ventral striatum of unmedicated schizophrenics during presentation of reward-indicating and loss-indicating stimuli. METHODS A total of 10 schizophrenic men (7(More)
Recent functional neuroimaging studies have emphasized the role of the different areas within the left superior temporal sulcus (STS) for the perception of various speech stimuli. We report here the results of three independent studies additionally demonstrating hemodynamic responses in the vicinity of the planum temporale (PT). In these studies we used(More)
OBJECTIVE Alcohol dependence may be associated with dysfunction of mesolimbic circuitry, such that anticipation of nonalcoholic reward fails to activate the ventral striatum, while alcohol-associated cues continue to activate this region. This may lead alcoholics to crave the pharmacological effects of alcohol to a greater extent than other conventional(More)
BACKGROUND Alcohol dependence is often associated with impulsivity, which may be correlated with dysfunction of the brain reward system. We explored whether functional brain activation during anticipation of incentive stimuli is associated with impulsiveness in detoxified alcoholics and healthy control subjects. METHODS Nineteen detoxified male alcoholics(More)
Clinical studies in patients with schizophrenia suggest that atypical neuroleptics are more effective than typical neuroleptics in reducing negative symptoms including apathy and anhedonia. Dysfunction of the dopaminergic reward system may contribute to negative symptoms in schizophrenia. We used functional magnetic resonance imaging to assess the blood(More)
OBJECTIVE Although it is well established that cerebral activation increases with higher task load, the potential effects of training have been investigated over brief periods only. Training is of potential clinical relevance since training programs are an essential part of psychiatric therapy. METHOD Cerebral activation during a visual spatial working(More)
We examined the processing of verbal and nonverbal auditory stimuli using an event-related functional magnetic resonance imaging (fMRI) study to reveal the neural underpinnings of rapid temporal information processing and it's relevance during speech perception. In the context of a clustered sparse-temporal fMRI data collection eight right-handed native(More)
Applying functional magnetic resonance imaging (fMRI) techniques, hemodynamic responses elicited by sequences of pure tones of 950 Hz (standard) and deviant tones of 952, 954, and 958 Hz were measured before and 1 week after subjects had been trained at frequency discrimination for five sessions (over 1 week) using an oddball procedure. The task of the(More)
An effect of finger tapping rate on the hemodynamic response in primary motor cortex and the cerebellum has been well established over the last years (the rate effect). The present study compares the magnitude of this effect when either the dominant or subdominant hand is used by right and left handers. In contrast to previous studies maximum and convenient(More)
