We studied the neural activation associated with anticipations of emotional pictures using functional magnetic resonance imaging (fMRI) by directly comparing certain with uncertain anticipation conditions. While being scanned with fMRI, healthy participants (n=18) were cued to anticipate and then perceive emotional stimuli having predictable (i.e., certain)(More)
A number of clinical studies in which early adversities were defined retrospectively, demonstrated that early adverse experiences increased the morbidity rate of post-traumatic stress disorder (PTSD) in later life. However, no prospective studies have yet been conducted to elucidate whether early adversity affects the risk or severity of PTSD. Thus, we(More)
Rodent studies have revealed that the early rearing environment plays an important role in the development of stress vulnerability, memory and cognition. Although early lighting conditions (ELC) are involved in these neuronal developments through both maternal and offspring behavior, their influence has not been fully elucidated. Thus, by using(More)
UNLABELLED Pain is a multidimensional phenomenon. Previous psychological studies have shown that a person's subjective pain threshold can change when certain emotions are recognized. We examined this association with magnetoencephalography. Magnetic field strength was recorded with a 306-channel neuromagnetometer while 19 healthy subjects (7 female, 12(More)
BACKGROUND Altered emotional memory is one of the core cognitive functions that causes and maintains depression. Although many studies have investigated the relationship between hippocampal volume, depression and treatment response, no studies have investigated the relationship for hippocampal activity. Additionally, few studies have examined the(More)
In general, emotion is known to enhance memory processes. However, the effect of emotion on associative memory and the underling neural mechanisms remains largely unexplored. In this study, we explored brain activation during an associative memory task that involved the encoding and retrieval of word and face pairs. The word and face pairs consisted of(More)
Diagnosis of psychiatric disorders based on brain imaging data is highly desirable in clinical applications. However, a common problem in applying machine learning algorithms is that the number of imaging data dimensions often greatly exceeds the number of available training samples. Furthermore, interpretability of the learned classifier with respect to(More)
BACKGROUND The judgment of the approachability of others based on their facial appearance often precedes social interaction. Whether we ultimately approach or avoid others may depend on such judgments. METHOD We used functional magnetic resonance imaging to determine the neural basis for such approachability judgments and the relationship between these(More)
BACKGROUND A few studies have used pseudo-continuous arterial spin labeling (pCASL) to assess the regional cerebral blood flow (rCBF) in patients with major depressive disorder (MDD). However, rCBF changes during treatment with escitalopram have not been studied in detail. We used pCASL to investigate the effect of 6-week escitalopram treatment on the rCBF(More)
