Disconnection Syndrome

A more comprehensive issue than frontal lobe syndromes.

I particularly like this paragraph.

Given that neuropsychiatric manifestations secondary to disruption of the frontal circuitry have been cited in this section, it follows that other semiological changes that can feature in the clinical picture of “frontal syndromes” should also be mentioned. Some of these changes include grouping, grasping, perseveration, snouting, imitation and utilization behavior, palmomental reflex, and persistent glabellar tap reflex [13, 14].


The Irish are sensitive about the history of having been imported as cheaper labor to dig canals and then having to be replaced by slaves whose purchase price was high. While some obstreperous male slaves were sold away and many plantations, set up with borrowed money by impecunious owners who wasted money on vacations to Europe, went bankrupt necessitating the sale of slaves, the people who did all the work negotiated a five and a half day work week, land for kitchen gardens, no labor for children under ten, nor for the aged who deserved to be sustained without working excapt for perhaps supervising the young. The slave population in North America did not flourish because the natural environment was milder, but because they had organized a sustainable way of life. It was the lazy Europeans who could not keep it together and spent more than they earned, behavior that keeps being imitated by industrial enterprise. Poor management focuses on manipulating manpower rather than the physical assets and resources that are needed. It is no wonder Europe is now more prosperous. For centuries they kept exporting their incompetents to the West. Who are the rednecks in the South? Descendants of Scots and Irish. If they are impoverished, as many are, it is not because they are genetically hampered, but because that is the result of poor nutrition, poor health care and poor sanitation. The KKK was organized out of jealousy that the freedmen thrived. Incompetents are hampered by the fact that work is largely invisible and they cannot immitate what they cannot see (sequence, order, time, distance, process, relationship). It seems strange that the cognitive functions are co-located with vision in the frontal lobes, but in some people the processing is not activated. Perhaps disconnection syndrome explains it. How do the lobes become disconnected? Nobody knows. I suspect it is a mild version of what we call cerebral palsy. A short in the circuits because of a brief lack of oxygen.
