The sMRI sequences (T1, T2, FLAIR, susceptibility-weighted imaging (SWI) and gradient-recalled echo (GRE)) provide highly accurate depiction of pathological lesions, and dMRI detects the effects of TBI on brain connectivity and non-hemorrhagic diffuse axonal injury (DAI), which are not detected by CT.
The number of published studies on the effects of anesthetic/sedative drugs on brain connectivity is still relatively small, and there is no consensus in this area.
Therefore, understanding the effects of traumatic axonal injury on brain function and behaviour is likely to require a detailed investigation of the global effects of traumatic axonal injury on brain connectivity.
Work on brain connectivity has already raised the prospect of using scans to select fast learners during recruitment drives.
Studies that emphasized the genetic influences on brain connectivity.
On the next day, however, no differences were found in free word recall or cued location-word association recall between conditions; and ghrelin's effects on brain activity or functional connectivity were unrelated to memory performance.
Pubertal sex steroids have organizational and activating effects on brain structure, and on structural and functional connectivity (see reviews by Sisk and Zehr 2005; Peper et al. 2011a, b; Ladouceur et al. 2012).
Consequently, any observed changes in connectivity patterns with sedative concentrations of propofol will represent effects on brain activity itself.
These include direct effects on brain function and structure by neurogenesis, angiogenesis, synaptogenesis, hippocampal volume, attenuated frontal loss of grey and white matter, and increased connectivity on the large scale brain circuitry [ 49].
