![]() ![]() Our results show that the TPJ in both hemispheres hosts multiple neural processes with connectivity patterns consistent with well developed specialization and lateralization.Ĭortical parcellation inferior parietal lobule probabilistic independent component analysis resting-state functional connectivity supramarginal and angular gyrus temporoparietal junction cortex.Ĭopyright © 2015 the authors 0270-6432-14$15.00/0. 5 Model of learning In this section, we will derive neural scaling law (4) for Santa Fe processes with a multiperiodic narration. Another subdivision that also had left- and right-biased ICs was connected to social or default mode networks. 1 day ago &0183 &32 Hence for the Santa Fe process as above, we have Hilberg’s law (10) with h 0 and c(c+ 1). One subdivision that presented as distinct left- and right-biased ICs was connected to frontoparietal regions. One bilateral subdivision was connected to sensorimotor regions and another was connected to auditory regions. The right-biased IC was connected with a network often associated with attentional processing. (GPs) are popular choices of this approach. This confirmed that the subdivisions belonged to distinct networks. In the Bayesian machine learning literature, non-parametric models such as Gaussian Processes. To test whether the independent components (ICs) reflected true subdivisions, we performed functional connectivity analysis using the IC coordinates as seeds. We identified four subdivisions that were bilaterally symmetrical and one that was right biased. ![]() The localized analysis allowed finer separation of processes and the use of multiple dimensionalities provided qualitative information about lateralization. We applied independent component analysis (ICA) to task-free fMRI data within a local region around the bilateral TPJ, iterating the ICA at multiple model orders and in several datasets. Here, we address this problem using data-driven analysis to test the hypothesis that the bilateral TPJ can be parcellated into subregions. The cell body produces proteins needed for the. The central cell body is the process part of a neuron and contains the neuron's nucleus, associated cytoplasm, organelles, and other cell structures. Neurons contain the same cellular components as other body cells. One major challenge is the lack of consensus about the anatomical location and extent of the TPJ. A neuron consists of two major parts: a cell body and nerve processes. Imaging studies have identified TPJ activation in association with many higher-order functions such as theory-of-mind, episodic memory, and attention, causing debate about the distribution of different processes. The human temporoparietal junction (TPJ) is a topic of intense research. ![]()
