  • Close follow-up is indicated due to the risk of these lesions progressing to invasive squamous cell carcinoma. (msdmanuals.com)
  • When a patient has lesions all over the brain, we used to assume they were unrelated to depression, because they seemed so disconnected. (rehabpub.com)
  • For each patient, estimated connectivity between lesion locations was determined using a connectome database, a large-scale wiring diagram of the human brain which has been made possible by initiatives such at the Human Connectome Project. (rehabpub.com)
  • In this research we present a new approach to the classification of melanocytic lesions. (hindawi.com)
  • The proposed automatic algorithm contains the following steps: image enhancement, lesion segmentation, feature extraction, and selection as well as classification. (hindawi.com)
  • Although a number of histological classification systems for CNS lesions have been used by different groups in recent years, no uniform classification exists. (nih.gov)
  • Non-proliferative lesions of the alimentary canal in rats GI-1. (nih.gov)
  • The unimpaired forelimb in lesioned rats was immobilized with a one-sleeved cast during the period of dendritic enhancement (days 1-15 postlesion). (jneurosci.org)
  • To test this, the authors overlaid these lesion locations on a map of the brain known as the connectome -a structural map of region to region connectivity derived from functional MRI data. (scientificamerican.com)
  • With the lesions applied to the connectome, the authors were able to identify networks-or tracks of connectivity-that the lesions disrupted. (scientificamerican.com)
  • Using the connectome database and LNM, the team found significant functional connectivity between MS lesion locations and their a priori depression circuit. (rehabpub.com)
