  • The lesion may be compact, containing a core of tightly packed venous loops, or it may be diffuse, with anomalous vessels dispersed among normal brain parenchyma. (medscape.com)
  • Paul Buchheit (creator of Gmail and Friendfeed) calls this "the social brain" - with emphasis on the social networks and collective social interactions that are taking place. (novaspivack.com)
  • Structural and functional brain networks are modular. (biorxiv.org)
  • However, modules delineated in structural brain networks inferred from tractography generally do not recapitulate canonical functional systems. (biorxiv.org)
  • In their brains, the two networks are activated in tandem. (brainblogger.com)
  • Growing evidence suggests that Internet-related addictions are also associated with breakdown of functional brain networks. (researchgate.net)
  • functional brain networks. (researchgate.net)
  • Areas of the brain work in concert with one another, forming functional networks defined by the connections between them. (findaphd.com)
  • Constant regulation of communication between all these nerve cells is required for the brain to develop and work effectively -- a process that makes the networks in the brain increasingly complex. (lu.se)
  • Another functional MRI study demonstrates reduced activity in both anterior cingulate cortex and visual areas under hypnosis. (brainblogger.com)
  • When comparing machines that gave dollar-bill payouts, levels of activity in the brain were similar in people with and without schizophrenia. (uclahealth.org)
  • However, when comparing machines that gave payouts of human smiling faces, the level of activity in the brain was much lower in people with schizophrenia than in healthy individuals. (uclahealth.org)
  • The brains of individuals with schizophrenia were less reactive to social rewards. (uclahealth.org)
  • To my knowledge, that level of [memory] improvement is far greater than anything that has been reported for healthy older adults and we also found a critical memory pathway in their brains improved to a similar extent relative to unenriched older adults," senior investigator Michael Leon, PhD, professor emeritus, University of California, Irvine, told Medscape Medical News .
