In seedtovoxel analysis, you define the seeds in the 'firstlevel analysis' step by selecting one or several 'sources' (these include all of your defined ROIs) Seedtovoxel analyses compute first the mean timeseries within each ROI and then compute the correlation between these average timeseries and the BOLD timeseries at each voxel (after001) Bilateral hand motor seeding was superior to unilateral hand motor seeding in patients with brain tumor forSeedbased functional connectivity, also called ROIbased functional connectivity, finds regions correlated with the activity in a seed region In seedbased analysis, the crosscorrelation is computed between the timeseries of the seed and the rest of the brain (telling us where the traffic is communicating between selected cities) (Fig 3, the results are visualized with

Seed region brain-Different regions of the brain's sensorimotor system fluctuated slowly and synchronously in the absence of any explicit task It was the first step toward the study of "restingstate connectivity," an approach that promises to help researchers study the functional organization of both the healthy and abnormal brain, particularly inRESULTS Localization of the supplementary motor area using hand motor seed regions was more effective than seeding using orofacial motor regions for both patients with brain tumor (955% versus 348%, P <

The CoCoMac database (8) is an online resource compiling results from hundreds of tracer studies found in the literature The user enters a brain region or abbreviation as a search query, and the result is a list of reported connections between that region and others For each "seed" region used as a search query, all regions with qualifying connections documented were recorded, to create aThis paper presents a beamformerbased imaging method, beamformerbased imaging of PAC (BIPAC), to quantify the strength of PAC between a seed region and other brain regionsApproach A dipole is used to model the ensemble of neural activity within a group of nearby neurons and represents a mixture of multiple source components of cortical activityThe emotional brain represents one of the 'three brains' proposed by neuroscientist Paul MacLean in his 'Triune Brain' model MacLean referred to the limbic system, which is largely in control of the human emotional response, as the paleomammalian brain This region is thought to have developed some time after the 'reptilian', or primal, brain
Segmentation of Magnetic Resonance Imaging (MRI) images is the most challenging problems in medical imaging This paper compares the performances of SeedBased Region Growing (SBRG), Adaptive NetworkBased Fuzzy Inference System (ANFIS) and Fuzzy cMeans (FCM) in brain abnormalities segmentation Controlled experimental data is used, which designed in such a wayThe regions connected to each of the individual seeds also followed the expected pattern The vmPFC seed was more strongly positively correlated with adjacent frontal and temporal regions, whereas the PCC seed was more correlated with nearby mid‐ and lateral parietal regionsThis paper proposes an empirical study of the efficiency of the SeedBased Region Growing (SBRG) in segmentation of brain abnormalities Presently, segmentation poses one of the most challenging problems in medical imaging Segmentation of Magnetic Resonance Imaging (MRI) images is an important part of brain imaging research

Wholebrain signal regression offers the advantage of enhancing the spatial specificity of functional connectivity mapping especially in the case of subcortical seed regions (Fox et al, 09) However, a consequence of this technique is that positive and negative values are approximately balanced in computed correlation maps, although thePineal region tumours originate from deep within the centre of the brain, close to the third ventricle (one of the large fluid filled spaces) This means that patients often experience increased pressure inside the skull due to a buildup of cerebrospinal fluid (CSF), a condition known as hydrocephalusBackground Seedbased studies on restingstate functional connectivity (rsFC) in schizophrenia have shown disrupted connectivity involving a number of brain networks;
