Therefore, we predict that breakdown of these frontal connections following traumatic brain injury will similarly correlate with executive impairment.
By using only anatomical landmarks, we were able to visualize frontal connections both within and across hemispheres.
We also identified a subset of frontal connections available only to the term control group, consistent with our expectations.
Changes in the pre-SMA and its frontal connections can therefore affect both the objective capacity for voluntary control of action, and the subjective experience of agency.
Rapid feedback to primary visual cortex, but potentially also horizontal connections from dorsal to ventral regions, or parietal to frontal connections followed by feedback to ventral stream regions may all contribute to a detailed analysis of the visual scene.
That is, both parietal and frontal connections to IT cortex have been categorized as "top-down," and these associational operations (as opposed to sensory, "bottom-up") may use a different spatial organization of projecting neurons.
In the present manuscript we report that motor networks in subjects with brain tumours are comparable to those observable in control patients, and that left frontal connections between the PMA and SMAs are critical for motor performance.
These data suggest a pattern of early grey matter loss in limbic, cortical and subcortical regions, which have extensive prefrontal-frontal connections.
In healthy older individuals, white matter microstructure in the corpus collosum correlated with cardiorespiratory fitness (oxygen uptake (VO2) peak r = −0.458) with subsequent tractography suggesting pre-frontal connections associated with motor planning [ 79].
In spite of the massive bulk of the frontal callosal connections in man, ascertained consequences of their interruption are limited to disorders of motor control, with particular regard to bimanual coordination.
