We present the first purely event-based method for face detection using the high temporal resolution properties of an event-based camera to detect the presence of a face in a scene using eye blinks. Eye blinks are a unique and stable natural dynamic temporal signature of human faces across population that can be fully captured by event-based sensors. We show that eye blinks have a unique temporal signature over time that can be easily detected by correlating the acquired local activity with a generic temporal model of eye blinks that has been generated from a wide population of users. In a second stage once a face has been located it becomes possible to apply a probabilistic framework to track its spatial location for each incoming event while using eye blinks to correct for drift and tracking errors. Results are shown for several indoor and outdoor experiments. We also release an annotated data set that can be used for future work on the topic.The effect of remote ischemic preconditioning (RIPC) has been proposed that mediates the protective response in ischemia reperfusion injury (IRI) of various organs. In this study, we investigated the effect of RIPC in hepatic IRI, by assessing biomarker of oxidative stress and inflammatory cytokines. Moreover, we intended to demonstrate any such protective effect through nitric oxide (NO). Twenty-five rats were divided into the 5 groups (1) Sham; (2) RIPC; (3) hepatic IRI; (4) RIPC + hepatic IRI; (5) C-PTIO, 2-(4-carboxyphenyl)-4,5dihydro-4,4,5,5-tetramethyl-1H-imidazolyl-1-oxy-3oxide, + RIPC + hepatic IRI. RIPC downregulated the level of aspartate aminotransferase (AST), alanine aminotransferase (ALT), histologic damage, and activity of Malondialdehyde (MDA). However, there was no significant reduction in the level of tumor necrosis factor-alpha (TNF-α) and nuclear factor kappa B (NF-κB). AST and ALT levels, and hepatic tissue morphology in the C-PTIO group showed a significant improvement compared to those of the RIPC + hepatic IRI group. The application of RIPC before hepatic ischemia downregulated the oxidative stress, not the inflammatory cytokines. Moreover, these protective effect of RIPC would be mediated through the activation of NO as well as anti-oxidant effect.Attempts to predict the likelihood of positive morphological imaging related with PSA value in patients referred with biochemical recurrence were the focus of many studies. Using nuclear medicine modalities, numerous studies likewise had been performed for the same purpose, however mostly using C-11-labeled choline. For this purpose, we selected 193 prostate cancer patients from our database between 2006 and 2010. They had been referred to our department to undergo 18F-fluorethylcholine (FECH)-PET/CT due to biochemical recurrence after potentially curative procedures. As a result, in 84 out of 193 patients, 18F-FECH-PET demonstrated positive findings with an overall detection rate of 44%. Statistically, there was a significant difference in PSA values in positive findings vs. negative findings (p 70%) after radiation therapy alone. By contrast, patients after radical prostatectomy followed by salvage radiotherapy showed a low likelihood of local recurrence. In conclusion, PSA value was confirmed to have a determinant role in 18F-FECH-PET outcome. Moreover, there was a link between recurrence type and initial therapy, which-if prospectively confirmed-may play a guiding role in selecting the appropriate diagnostic methods.This case study was based on a popular press news article about Krystle Beauchamp Gridley's experience with meningitis while in college (Miller, 2019). Students in an introductory neuroscience course read the popular press news article as well as an empirical article that identified risk factors for contracting meningococcal disease in college (Bruce et al., 2001). Students used information from the empirical article to identify Krystle's risk factors for meningitis. Then, students evaluated their University's policy on students receiving the meningococcal vaccine based on what they had learned. This case supports two important goals of neuroscience education, 1) exposing students to primary scientific literature early in their undergraduate education and 2) developing an understanding of the broader implications of scientific research for society. Students enjoyed learning about meningitis using the case-study method, reading the primary scientific article, and considering how scientific research can be applied to policy decisions. Further, the case was instrumental in supporting the content and process learning objectives.Undergraduate neuroscience education has grown substantially in the US as well as participation in outreach and research activities by undergraduates. In line with these observations, undergraduates may also be seeking membership in the Society for Neuroscience (SfN) as well as attending the SfN annual meeting. Data in the present report show that undergraduate membership in SfN has increased between 2013 and 2019 as well as annual undergraduate SfN meeting attendance and abstract submissions for research presentations. Increases were observed for both US and international undergraduates. These data are discussed in the context of motivations of undergraduates to pursue future academic training and/or careers in neuroscience. These data are important to faculty and administrators at institutions that currently have or seek to establish new undergraduate neuroscience programs given membership in a professional society and attendance at a major conference can positively impact academic and professional development.The crayfish stretch receptor organ (SRO) preparation represents a robust experimental model for undergraduate laboratory experiences. For example, this preparation may be included as part of a course-based undergraduate research experience (CURE), where students work independently to plan and carry out their own experiments. In the current paper, we provide an example of how local anesthetics may be used to manipulate the SRO preparation and to perform quantitative analyses of SRO action potential firing rates. check details Local anesthetics provide interesting tools for manipulating physiological responses within the nervous system. A variety of inexpensive anesthetics are available for student use and each of these is expected to inhibit neurophysiological responses. While specific anesthetics exhibit subtle differences in chemical organization, they are generally understood to block voltage gated sodium channels. In the current study, we investigated the effects of two local anesthetics, MS-222 and procaine, on the action potential firing rate from the crayfish SRO.
