Optimized brain extraction for pathological brains (optiBET). in the context of the segmentation of brain from non-brain tissue (i.e., brain extraction, also known . White matter hyperintensities (WMHs), evidence of compromised white matter integrity, are common in clinical populations (e.g., cancer, stroke, multiple sclerosis, older adults) and older adult community samples, suggesting white matter's … The script has now been tested on a set of more than 70 patient brains, and it performs better than all available tools (see figure below). The Optimized Brain Extraction Tool (optiBET) (Lutkenhoff et al., 2014) was used to remove any excess unwanted structures in high resolution T1 images, e.g., skull, eyes, etc. Looking for consciousness, the aware mind in the motionless body, The Psychologist 23(6):478-481, 2010 . Briefly, MR images were brain-extracted using optiBET (Lutkenhoff et al., Reference Lutkenhoff, Rosenberg, Chiang, Zhang, Pickard, Owen and Monti 2014), then the thalamus, caudate, putamen, globus pallidus, hippocampus, and brainstem were segmented using FSL FIRST (Patenaude, Smith, Kennedy, & Jenkinson, Reference Patenaude, Smith, Kennedy and . (2017), which evaluated the replicability, specificity, and generalizability of connectome fingerprints. 1-13 2002; 17:143-155. doi: 10.1002/hbm.10062 Crossref Medline Google Scholar; 31. Genetic algorithms have a proven capability to explore a large space of solutions, and deal with very large numbers of input features. Rather than attempting to trace the boundary between tissues, optiBET performs brain extraction by (i) calculating an initial approximate brain extraction; (ii) employing linear and non-linear registratio It is demonstrated that a deep learning model trained on minimally processed automatically-generated labels can generate more accurate brain masks on MRI of brain tumor patients within seconds. Composite wavelet filters for enhanced automated target recognition . Most skull-stripping methods are optimized and validated on T 1-w images, since high resolution T 1-w structural images are prevalent in clinical studies.

"In terms of brain function, the difference between being conscious and unconscious is a bit like the difference between driving from Los Angeles to New York in a straight line versus having to cover the same route hopping on and off several buses that force you to take a 'zig-zag' route and stop in several places."

Magnetic resonance imaging (MRI) is one of the most widely used imaging techniques in neuroimaging pipelines. Highly influential models have proposed that responses to different types of threat are mediated by partially segregated neural systems, with the amygdala underlying phasic responses to explicit threat fear and the bed nucleus of the stria terminalis BNST mediating sustained responses to ambiguous threat anxiety.
