Prefrontal interactions reflect future task operations.

When task instructions are given, the human brain establishes a task set before the task is actually performed. By introducing a delay between the instruction and the task, we have identified the neural correlates of task sets using functional magnetic ...

Genetic and environmental influences on human psychological differences.

Psychological researchers typically distinguish five major domains of individual differences in human behavior: cognitive abilities, personality, social attitudes, psychological interests, and psychopathology (Lubinski, 2000). In this article we: discuss ...

Driving ability under long-term treatment with transdermal fentanyl.

Clinical experience shows that neuropsychological side effects due to opioid therapy usually decrease during the first weeks of therapy. However, the effect of long-term treatment with transdermal fentanyl on complex activities, such as driving, is not ...

The human amygdala and the emotional evaluation of sensory stimuli.

A wealth of animal data implicates the amygdala in aspects of emotional processing. In recent years, functional neuroimaging and neuropsychological studies have begun to refine our understanding of the functions of the amygdala in humans. This literature ...

The relationship between P3 and neuropsychological function in an adult life span sample.

The relationship of P3 to age and neuropsychological performance was investigated in a sample of 71 well-functioning adults ranging in age from 21.8 to 94.7 years. ERPs were recorded while the participants performed an auditory two-stimuli oddball task ...

From humble neural beginnings comes knowledge of numbers.

Following a recent report that monkey prefrontal cortex contains cells that represent number concepts, Nieder and Miller investigated the scale used to code numbers. In this issue of Neuron, they report that prefrontal cells use the same scale (Webers ...

The dual factor structure of self-rated MDQ hypomania: energized-activity versus irritable-thought racing.

BACKGROUND: Bipolar II is diagnosed in a clinically depressed patient by documenting history of hypomania. Therefore, it is of great significance for both clinical and research purposes to characterize the factor structure of hypomania. METHODS: Among ...

Steroid-induced elevation of glucose in Alzheimers disease: relationship to gender, apolipoprotein E genotype and cognition.

Glucose and insulin may play an important role in the pathophysiology and symptomatology of Alzheimers disease (AD), and prior studies suggest interactions among glucose, insulin, gender and apolipoprotein E genotype. We analyzed the relationship between ...

Coordinated turn-and-reach movements. II. Planning in an external frame of reference.

The preceding study demonstrated that normal subjects compensate for the additional interaction torques generated when a reaching movement is made during voluntary trunk rotation. The present paper assesses the influence of trunk rotation on finger ...
