Thinking of the future and past: the roles of the frontal pole and the medial temporal lobes
We measured regional cerebral blood flow (rCBF) in healthy subjects while they were talking about their future prospects or past experiences, with regard to two different temporal windows (in years or days) and a naturalistic task setting. Expand

Specific brain processing of facial expressions in people with alexithymia: an H2 15O-PET study.
Alexithymia is a personal trait characterized by a reduced ability to identify and describe one's own feelings and is known to contribute to a variety of physical and behavioural disorders. ToExpand

Dissociable roles of prefrontal and anterior cingulate cortices in deception.
Recent neuroimaging studies have shown the importance of the prefrontal and anterior cingulate cortices in deception. However, little is known about the role of each of these regions duringExpand

Correlation between alexithymia and hypersensitivity to visceral stimulation in human
Abstract Empirical studies indicate that alexithymia exacerbates physical illness. However, direct evidence to explain the mechanism of this exacerbation has not been provided. One hypothesis is thatExpand

Central Effects of Fexofenadine and Cetirizine: Measurement of Psychomotor Performance, Subjective Sleepiness, and Brain Histamine H1‐Receptor Occupancy Using 11C‐Doxepin Positron Emission Tomography
Histamine H1‐receptor (H1R) antagonists, or antihistamines, often induce sedative side effects when used for the treatment of allergic disorders. This study compared the sedative profiles of theExpand
