leprae in humans. Moreover, our report sheds light on the potentially critical adhesins involved in M. leprae-epithelial
cell interaction that may be useful in designing more effective tools for leprosy control.”
“The temporal perception of simple auditory and visual stimuli can be modulated by exposure to asynchronous audiovisual speech. For instance, research using the temporal order judgment (TOJ) task has shown that exposure to temporally misaligned audiovisual speech signals can induce temporal adaptation that will influence the TOJs of other (simpler) selleck inhibitor audiovisual events (Navarra et al. (2005) Cognit Brain Res 25:499-507). Given that TOJ and simultaneity judgment (SJ) tasks appear to reflect different underlying mechanisms, we investigated whether adaptation to asynchronous speech inputs would also influence SJ task performance. Participants judged whether a light flash and a noise burst, presented at varying stimulus onset asynchronies, were simultaneous or not, or else they discriminated which of the two sensory events appeared to have occurred first. While performing these tasks, participants monitored a continuous speech stream for target words that were either presented in synchrony, or
with the audio channel lagging 300 ms behind the video channel. We found that the sensitivity of participant’s TOJ and SJ responses was reduced when the background speech stream was desynchronized. A significant modulation of the point of subjective MK-8776 datasheet simultaneity (PSS) was also observed in the SJ task but, interestingly, not in the TOJ task, thus supporting previous claims that TOJ and SJ tasks may tap somewhat different Selleckchem ALK inhibitor aspects of temporal perception.”
“There is now substantial evidence that during visual search,
previously searched distractors are stored in memory to prevent them from being reselected. Studies examining which memory resources are involved in this process have indicated that while a concurrent spatial working memory task does affect search slopes, depleting visual working memory (VWM) resources does not. In the present study, we confirm that VWM load indeed has no effect on the search slope; however, there is an increase in overall reaction times that is directly related to the number of items held in VWM. Importantly, this effect on search time increases proportionally with the memory load until the capacity of VWM is reached. Furthermore, the search task interfered with the number of items stored in VWM during the concurrent change-detection task. These findings suggest that VWM plays a role in the inhibition of previously searched distractors.”
“The Currarino triad is a complex genetic disorder characterized by multiple caudal anomalies. Currarino et al first described this syndrome in 1981 as a sacral bony defect, presacral mass, and an anorectal malformation.
