This year's neuroscience special issue is devoted to general and also several more
specific aspects of research on
connectivity in the
brain.
The discovery of
connectivity deficits in a
specific region of the
brain like the SLF provides an important starting point for more research on people with IED, as well as those with borderline personality disorder, who share similar social and emotional problems and appear to have the same abnormality in the SLF.
Autism and other
specific mental disorders may be caused in part by «
specific circuits or regions of the
brain [that] had problems with
connectivity,» Krienen says.
«Research indicates that the
brain is functionally organized according to intrinsic
connectivity networks, which are known to play a central role in
specific facets of intelligence.
Most prominent effects between IQ and the level of global
connectivity efficiency (as expressed by a shorter node
specific normalized path length) were found in the medial prefrontal cortex (yellow box), bilateral inferior parietal cortex (red box depicts effect in right hemisphere), and precuneus / posterior cingulate regions (orange box) of the functional
brain network.
Our data reflects the level of efficient organization of the functional
brain network during a resting state and not the efficiency of functional
connectivity between
brain regions during the performance of
specific cognitive tasks that enter into the IQ score.
Long - lasting changes in
brain connectivity require new gene expression, and Dr. Martin has discovered a role for
specific signaling molecules that travel from stimulated synapses to the nucleus to change the transcription of DNA to RNA.
An important area for future work will be to understand functional
connectivity abnormalities in ASD at the global level, across the whole
brain, as well as in
specific functional networks or sets of nodes.
Central adaptations might involve the reduction of the eccentric -
specific voluntary activation deficit, perhaps by either increased net excitability of the spinal reflex pathway, or by increased motor learning through increased functional
connectivity between the primary motor cortex and other parts of the
brain.
The study essentially correlates
specific patterns of
brain connectivity — the degree to which different parts of the human
brain talk to each other — with a suite of what are generally considered positive traits, such as education, income, and self - control.
