brain structure and function journal impact factor

The impact factor (IF) 2019 of Brain Structure and Function is 3.298, which is computed in 2020 as per it's definition. High-Impact Articles . February 2009, issue 3. Brain Sciences. Volume 213 September 2008 - October 2009. Given that at best 37% of the variance could be explained by the model of a purely stationary FC (the SAR), we can wonder why the models of higher complexity used in our simulation testbed did not perform better in predicting FC. For each subject, the preprocessing yielded three matrices: one of SC, one with the average fiber lengths, and one of empirical FC. Found insideThis book is meant to integrate the emerging body of information that has been accumulating, revealing the interactive nature of the brain's two major neural cell types, neurons and glia, in brain function. Experiences occurring during this period permanently modify brain structure and function through epigenetic modifications (alterations of the DNA structure and chromatin function) and consequently affect the susceptibility to mental disorders. Journal Impact Factor: 1.45*, 1.21 (5 Years Impact Factor) Global Impact Factor: 0.654. The results above show that SC plays a causal role in FC, but one can still wonder what aspects of the underlying dynamics are the most directly related to this influence. The main objective of the journal is to disseminate the scientific work, publication, education, and exchange of ideas globally. SCImago Journal Rank (SJR indicator) is a measure of scientific Found insideStudies of memory deficits in disease models are introduced as well as approaches to restore memory deficits.

The March 2015 study, “Family Income, Parental Education and Brain Structure in Children and Adolescents,” was published in the online edition of the journal Nature Neuroscience. Further knowledge about this stationary process might be gained by analyzing FC computed over much longer periods of time than is commonly performed (e.g., hours versus minutes). Exploration of the parameter space for the Fitzhugh-Nagumo model. We approached this question by computing predictive power on windowed FC as a function of the length of the time-window used [22], for all possible time-windows over which FC could be estimated and for all models. In particular, the existence and relative contributions of anatomical constraints and dynamical physiological mechanisms of different types remain to be established. Yes Biological Psychiatry, founded in 1969, is an official journal of the Society of Biological Psychiatry and the first in the Biological Psychiatry family of journals. Special Issue in Brain Sciences: Brain Disorders: Affecting Brain Function, Structure and Neurochemistry Brain Sci. In all cases, the predictive power decreased as a function of the proportion of connections manipulated (Figure 2, panel B). Service members and veterans were enrolled in a trial with a new type of brain training program, based on the science of brain plasticity and the discovery that intensive, adaptive, computerized training—targeting sensory speed and accuracy—can rewire the brain to improve cognitive function. Without adding homotopic connections in the SC matrix, the simulated networks highly differed from the empirical networks. Currently health care pathways (the combination and order of services that a patient receives to manage their injury) following a mild traumatic brain injury vary considerably. No, Is the Subject Area "Simulation and modeling" applicable to this article? Mitochondria impact brain function and cognition. One possible hypothesis is that the SAR model was favored in the simulations, because we estimated FC over about 10 minutes of actual brain dynamics. As we showed, even naive manipulations aimed at estimating the impact of the known errors in DWI-based reconstruction of homotopic connections showed that such errors could cause 20% of the unexplained variance in predicting empirical FC. Found inside – Page 172Journal of Trauma and Dissociation, 6(2):123–130, 2005. J. D. Bremner. Effects of traumatic stress on brain structure and function: Relevance to early ... Since SC is furthermore expected to drive FC, we can hypothesize that this stationary process contributes to generate a stationary FC. Network maps for the average subject and empirical FC, as well as for FC simulated using either the SAR model with original SC or the SARh. In particular, most networks were found to be lateralized. The results show that for the models we used, with their sets of parameters, an increase in complexity was not associated with an increase in performance. The average predictive power was lower for shorter time-windows and increased towards a limit for longer time-windows. Contrary to our hypothesis H2, generative models had similar performance, and complexity was not predictive of performance. Brain imaging has radically changed our approach to the assessment of brain structure and function - and also to structural alterations and dysfunction in a disease-related context. As the brain matures, more and more fibers grow and the brain becomes increasingly interconnected. Simulated fMRI BOLD signal was obtained from simulated neuronal activity by means of the Balloon-Windkessel hemodynamic model [50], [51]. Lacaux et al. It is plastic or malleable, and the term neuroplasticityis used to describe this tendency for the brain to keep developing, changing, and potentially healing itself. In spite of the complexity of the problems and the limitations of current modeling approaches, computational modeling of large-scale brain dynamics remains an essential scientific endeavor.

It is thus difficult to infer how much of the 63% of unexplained variance remaining in whole-session FC actually reflect physiologically meaningful non-stationary FC, and more broadly, non-stationary dynamics. Characterizing its structure and function has implications for health and disease, impacting nutrition and obesity, brain function, allergic responses, immunity, inflammatory bowel disease, irritable bowel syndrome, cancer development, cardiac disease, liver disease, and others. Now, realism usually comes at the cost of complexity. Beyond predicting the overall pattern of FC, we also assessed whether models could predict the empirical organization of FC into a set of intrinsic networks. A journal impact factor is frequently used as a proxy for the relative importance of a journal within its field. Brain has published landmark papers in clinical neurology and translational neuroscience since 1878. For color code see Figure 1. https://doi.org/10.1371/journal.pcbi.1003530.g003. Matrices were rearranged such that network structure is highlighted. High FC between the amygdala and ventral-lateral sectors of the prefrontal cortex was also correctly predicted by the simulations. (Right) Predictive power as a function of α and β. For more details, see Text S2. For each graph, predictive power was quantified as a function of the percentage of connections manipulated. Modeling performance was assessed using predictive power and similarity of spatial patterns. Empirical and simulated windowed FC were computed on individual subjects using sliding time-windows (increment of 20 s) of varying length (from 20 to 420 s by step of 20 s). This suggests that, for these models, complexity and realism are not quite as tightly connected as expected. While anatomy and dynamics are organically intertwined (anatomy contributes to shape dynamics), the nature and strength of this relation remain largely mysterious. Editorial Procedure. Regarding the similarity of functional brain networks, SC, empirical FC and simulated FC were decomposed into 10 networks using agglomerative hierarchical clustering and generalized Ward criterion [52]. In order to bring together the structural and dynamical components underlying FC, some studies have used computational models that incorporate SC together with biophysical models of neuronal activity to generate coherent brain dynamics [27]–[32]. Performance of computational models when no global signal regression was performed. Brain Structure & Function publishes research that provides insight into brain structure−function relationships. The SAR model, introduced in [36], may appear well-suited to model essential stationary aspects of the generative mechanisms of FC. Brain Communications is the open access sister journal to Brain. September 2009, issue 4-5. Found inside" Based on the expertise of more than 100 neuroscientists and computer specialists, this new volume examines how computer technology can meet that need.

Predictive power as a function of time-window length across subjects (left) and of duration of simulated runs on the average subject (right). We also reveal the critical importance of specific anatomical connections in shaping the global anatomo-functional structure of this dynamical regime, notably connections between hemispheres.

In agreement with our hypothesis H1, we showed that functional connectivity could at least in part be explained by structural connectivity alone. We addressed this issue by systematically comparing functional connectivity (FC) from resting-state functional magnetic resonance imaging data with simulations from increasingly complex computational models, and by manipulating anatomical connectivity obtained from fiber tractography based on diffusion-weighted imaging. The brain and the spinal cord make up the central nervous system, which alongside the peripheral nervous system is responsible for regulating all bodily functions. In this study, we demonstrate the existence (and quantify the contribution) of a dynamical regime in the brain, coined ‘stationary’, that appears to be largely induced and shaped by the underlying anatomy.
