Brain imaging work

The UC Davis M.I.N.D Institute (Medical Investigation of Neurodevelopment Disorders) explains the various advances in brain research like this, "Advances in imaging technology are enabling researchers to unravel the complexity of brain function. Functional magnetic resonance imaging (MRI) permits researchers to identify areas of the brain at work during specific activities and... 

The effort to understand those brain functions that account for variance in psychometric intelligence produced a set of replicated correlations with indices at different levels of explanation. Future work will add to these associations and should devote more effort to explaining these correlations. A part of this explanatory toil must come from linking individual differences at different levels of description. Some contributions toward that end were offered, including statistical modelling, pharmacological intervention, functional brain imaging and event related potential studies.

Several works had already been proposed and implemented previously to detect the lesion in brain images. Di-yana et al. detected the brain abnormalities by using symmetrical features [4]. To determine the symmetrical axis, any tilted brain image was rotated correctly. After that, the features in abnormal area such as area and centroid were used in the rule-based abnormalities detection. Meanwhile, Liu et al. also proposed another new method to detect the midline shift [5]. The new midline was formed by using linear regression model (H-MLS model). 

The last two decades have seen the introduction of several distinct functional imaging techniques that can be used to investigate centrally active compounds working in the brain in vivo. These techniques provide windows through which to observe phenomena in the intact and fully functional central nervous system. When applied to studies with human volunteers or patients one can obtain information that cannot be extrapolated from animal models, and from areas such as the brain and neurotransmitter systems that would otherwise be inaccessible in vivo. When combined with peripheral measurements and objective and subjective assessments of behavior, these methods can be used to explore how psychopharmaceuticals influence central nervous svtem activity and behavior. Moreover, compounds with a known mechanism of action can be employed as tools to understand how different elements of the central nervous system work.
