Concurrently, some prototypes of an MR-PET scanner for simultaneous human brain studies have been built, their performance is being tested and preliminary applications have already been shown.
A puzzling observation from autopsy AD brain studies has been the weak correlation between fibrillar Aβ load in the brain and cognition while the amount of neurofibrillary tangles significantly correlates with the cognitive status and duration of dementia [ 2- 4].
The design and the primary results of the Brain Power study have been reported elsewhere [ 21].
Data on cognition and brain imaging findings from this study have been reported previously [ 17].
Physiologically, little is known about why the teenagers are behaving like this – no brain imaging study has been carried out in the area.
Consequently, functional brain imaging studies have been conceived to investigate changes in brain function pain processing in particular—under TNFα inhibition.
In the last decade, a number of brain imaging studies have been done on patients suffering from hysterical paralysis.
Most human brain networks studies have been mainly focused on the global topological properties such as the average clustering coefficients, shortest path length and network efficiency [16], [23] [30], [32], [52].
(2) No functional brain imaging studies have been performed on rat models of AD.
Numerous brain imaging studies have been conducted on the neural correlates of spider phobia (e.g. Alpers et al., 2009; Dilger et al., 2003; Hermann et al., 2009; Paquette et al., 2003; Schienle et al., 2005, 2007; Straube et al., 2007).
