Spatiotemporal Analysis of Category and Target-related Information Processing in the Brain during Object Detection.
Spatiotemporal Analysis of Category and Target-related Information Processing in the Brain during Object Detection. Behav Brain Res. 2019 Jan 14;: Authors: Karimi-Rouzbahani H, Vahab E, Ebrahimpour R, Menhaj MB Abstract To recognize a target object, the brain implements strategies which involve a combination of externally sensory-driven and internally task-driven mechanisms. While several studies have suggested a role for frontal brain areas in enhancing task-related representations in visual cortices, especially in the lateral-occipital cortex, they have remained silent about the type of information transferred to visual areas. However, the recently developed methods of representational connectivity analysis, allowed us to track the movement of different types of information in the brain. Accordingly, we designed an EEG object detection experiment and inspected the spatiotemporal dynamics of category- and target-related information across the brain. Results showed that the prefrontal area initiated the processing of target-related information. This information was then transferred to posterior brain areas during stimulus presentation probably to facilitate object detection and to direct the decision-making procedure. We also observed that, as compared to category-related information, the target-related information could predict the behavioral performance more accurately, suggesting the dominant representation of internal compared to external information...
Conclusion: Based on these results NDDS is considered to be an applicable instrument for identifying personality pathology in patients with depressive symptoms, by recognizing the specific pattern. This is thought to be important for adequate treatment planning. PMID: 31517547 [PubMed - as supplied by publisher]

As a child born in 2018, my little girl has a one in three chance of living to 100. In contrast, as someone born in 1917, Pamela would have been considered lucky to live past 60.
CONCLUSIONS Our results demonstrated a regulation loop among MATAL1, miR-194, and YAP1, which dynamically regulates the progression of AP, providing a new therapeutic target for treatment of this disease. PMID: 31518341 [PubMed - in process]
