Brain Reaction to Experimental Injury After Hypothermia

BACKGROUND: Walking like many other actions of a human is controlled by the brain through the nervous system. In fact, if a problem occurs in our brain, we cannot walk correctly. Therefore, the analysis of the coupling of brain activity and walking is very important especially in rehabilitation science. The complexity of movement paths is one of the factors that affect human walking. For instance, if we walk on a path that is more complex, our brain activity increases to adjust our movements. OBJECTIVE: This study for the first time analyzed the coupling of walking paths and brain reaction from the information point of view. METHODS: We analyzed the Shannon entropy for electroencephalography (EEG) signals versus the walking paths in order to relate their information contents. RESULTS: According to the results, walking on a path that contains more information causes more information in EEG signals. A strong correlation (p= 0.9999) was observed between the information contents of EEG signals and walking paths. Our method of analysis can also be used to investigate the relation among other physiological signals of a human and walking paths, which has great benefits in rehabilitation science.

Degenerative Processes

Calcification of the fascicular zone of the cortex has been observer in 64 of 257 cats. It is always calcification and never ossification It is more common in young animals and in our experience is associated with distemper. In its severe forms it may be recognized clinically. The symptoms resemble those seen in cats surviving double suprarenalectomy for 2 to 3 weeks. The toxin producing the focal degeneration is dearly a very specific one since attempts to produce such lesions by several types of experimental injury have failed. The sequence of events appears to be similar to that present in other degenerative processes associated with calcification, namely cell injury and necrosis, deposition of calcium at first as fatty compounds which later change to carbonate and phosphate. It is suggested that this lesion should be considered in interpreting experiments in which cats are used.

Experimental Injury

✓ Biopsies from partially lacerated nerves were taken at the sites of proximal stimulus, laceration, and distal recording, and from stimuli and recording sites of control nerves. Electron microscopic examination of the partially lacerated major fasciculus revealed three zones of injury. The laceration zone showed neurotemetic changes, the adjacent or intermediate zone, partial degeneration, and the zone most peripheral to the laceration, changes in ground substance. Progression of the original injury is apparently due to ongoing changes in the intermediate and peripheral zones while much of the relative early recovery is due to reversal of changes in these zones. Regeneration through the laceration or neurotemetic zone is limited but does account for a small amount of late recovery of function.

Brain Reaction

Nicotine addiction is categorized as severe addiction immediately behind heroin. The third place on the list is cocaine addiction, followed by alcohol, etc. Nicotine is a powerful psychoactive substance that disrupts bio-cell processes and changes behavior. It causes dependence on smokers, but tar is a highly potent killing substance. Therefore, in 1965 the US Congress passed a law on mandatory health warning stickers on tobacco packs. Numerous studies have shown that the health warning does not affect the reduction in the number of cigarettes smoked, contrary to this warning motivates smokers to light-up a new cigarette. What actually happens in the smoker's heads and why? s the health warning a subtly designed subliminal message, or is its opposite effect a consequence of the brain filtration mechanism, or is it simply a synergy of the above-mentioned phenomena?
