BACKGROUND Transcranial magnetic stimulation (TMS) is a new technology for noninvasively stimulating the brain. Several studies have suggested that daily stimulation of the left prefrontal cortex with TMS for 2 weeks has probable antidepressant effects. We conducted a parallel-design, double-masked, sham-controlled study to address whether 2 weeks of daily(More)
In this paper we propose the first method known to the authors that successfully differentiates spontaneous from posed facial expressions using a realistic training corpus. We propose a new spatiotemporal local texture descriptor (CLBP-TOP) that outperforms other descrip-tors. We demonstrate that our temporal interpolation and visual/near-infrared fusion(More)
Facial micro-expressions are rapid involuntary facial expressions which reveal suppressed affect. To the best knowledge of the authors, there is no previous work that successfully recognises spontaneous facial micro-expressions. In this paper we show how a temporal interpolation model together with the first comprehensive spontaneous micro-expression corpus(More)
A robust automatic micro-expression recognition system would have broad applications in national safety, police interrogation, and clinical diagnosis. Developing such a system requires high quality databases with sufficient training samples which are currently not available. We reviewed the previously developed micro-expression databases and built an(More)
Much evidence from animal and clinical studies has shown that the mediodorsal nucleus of the thalamus (MD) is related to various types of memory, such as visual recognition, object-reward association, spatial working, and reference memory; however, few studies have investigated its role in emotion-related learning and memory processes. This study compared(More)
Selective serotonin reuptake inhibitors are first-line treatment for most anxiety disorders, but their mechanism of anxiolytic action has not been clarified. Selective serotonin reuptake inhibitors are anxiolytic in conditioned fear stress (re-exposure to an environment paired previously with inescapable electric footshocks). To clarify the brain regions(More)
— Micro-expressions are short, involuntary facial expressions which reveal hidden emotions. Micro-expressions are important for understanding humans' deceitful behavior. Psychologists have been studying them since the 1960's. Currently the attention is elevated in both academic fields and in media. However, while general facial expression recognition (FER)(More)
Heart rate is an important indicator of people's physiological state. Recently, several papers reported methods to measure heart rate remotely from face videos. Those methods work well on stationary subjects under well controlled conditions, but their performance significantly degrades if the videos are recorded under more challenging conditions,(More)
The present study investigated the effects of acute and chronic administration of the protein kinase C inhibitor, staurosporine, on the acquisition and expression of conditioned freezing behavior, an index of anxiety induced by conditioned fear stress. Results revealed that acute staurosporine (0.01 and 0.1 mg/kg, i.p.) did not affect either acquisition or(More)
This study examined the effects of combined treatment with the typical antipsychotic drug haloperidol and dopamine D1/5 receptor antagonist SCH 23390 on the acquisition of contextual conditioned fear (re-exposure to an environment paired previously with inescapable electric footshocks), compared with those of various antipsychotic adjuvants, which may(More)
