  • Previous studies which assess brain function in adults with autism using a technique called functional magnetic resonance imaging (fMRI) have defined the neural circuitry involved in a range of cognitive and psychological processes. (autismspeaks.org)
  • Finally, by defining functional brain phenotypes using fMRI, these studies have the potential to help differentiate subtypes of the autism spectrum, and provide clues into other causes of this disorder. (autismspeaks.org)
  • Common methods of functional neuroimaging include Positron emission tomography (PET) Functional magnetic resonance imaging (fMRI) Electroencephalography (EEG) Magnetoencephalography (MEG) Functional near-infrared spectroscopy (fNIRS) Single-photon emission computed tomography (SPECT) PET, fMRI and fNIRS can measure localized changes in cerebral blood flow related to neural activity. (wikipedia.org)
  • FMRI and PET enable creation of functional connectivity maps of distinct spatial distributions of temporally correlated brain regions called functional networks. (wikipedia.org)
  • This can be done noninvasively in humans by combining transcranial magnetic stimulation with one of the neuroimaging tools such as PET, fMRI, or EEG. (wikipedia.org)
  • GABA can be detected non-invasively using 1H magnetic resonance spectroscopy (MRS). We have recently shown that individuals with more GABA in occipital cortex tend to give smaller responses to visual stimuli as measured by functional magnetic resonance imaging (fMRI), suggesting that individual differences between healthy subjects may be a useful tool to investigate the mechanisms underlying the fMRI response.

  • Functional magnetic resonance imaging (fMRI) is a very powerful method that is used by scientists to see which areas of the brain are used to perform different tasks, and to look for functional differences between the brains of healthy subjects and patients. (grantome.com)
  • Diffusion Tensor imaging - DTI and voxel-based morphometry -VBM) and functional MRI (fMRI) defines a novel investigational platform that we have successfully employed to describe the intrinsic organization of the mouse brain in unprecedented detail. (iit.it)
  • This research leverages on the use of resting-state fMRI to obtain an integrated portrayal of the macroscale mouse functional connectome, i.e. the complex network of elements and connections that govern and compose the brain at the macroscale. (iit.it)
  • By using fMRI in transgenic mouse lines mouse we have begun to establish causal relationships between genetic ASD-related mutations, neurodevelopmental processes and functional connectivity alterations. (iit.it)
  • Entropy analysis of resting-state functional MRI (R-fMRI) is a novel approach to characterize brain temporal dynamics and facilitates the identification of abnormal brain activity caused by several disease conditions. (readbyqxmd.com)
  • He is best known for publishing a scientific paper in 2006 in the journal Science showing that some patients, thought to be in a vegetative state, are in fact fully aware and (shown subsequently) able to communicate with the outside world using techniques such as functional magnetic resonance imaging (fMRI) and electroencephalography (EEG).

  • Positron
  • Functional neuroimaging, such as single photon emission computed tomography (SPECT) and positron emission tomography (PET), initially showed promise in their ability to improve the diagnostic credibility of MTBI. (jaapl.org)
  • The overselling of SPECT or positron emission tomography (PET) neuroimaging by lawyers is a serious potential evidentiary concern in the civil litigation of MTBI. (jaapl.org)
  • detect
  • His 2006 paper in the journal Science demonstrated that functional neuroimaging could be used to detect awareness in a patient who was incapable of generating any recognised behavioural response and appeared to be in a vegetative state. (wikipedia.org)

  • activity
  • We are interested in understanding how large scale functional activity and network dynamics originate, develop and govern behavioural states. (iit.it)
  • We studied the utility of neuroimaging in providing objective evidence of neural activity related to drug modulation or a placebo effect in a double-blind, randomized, placebo-controlled, three-way crossover trial. (ox.ac.uk)
