Skeletal adaptations in young male mice after 4 weeks aboard the International Space Station.

Gravity has an important role in both the development and maintenance of bone mass. This is most evident in the rapid and intense bone loss observed in both humans and animals exposed to extended periods of microgravity in spaceflight. Here, cohabitating 9-week-old male C57BL/6 mice resided in spaceflight for ~4 weeks.

Technical and clinical aspects of topographic brain mapping.

TBM provides physiological and diagnostic information which is quite complementary to EEG, but does not replace the need for standard EEG recordings. For example, it does not show subtle morphologic abnormalities such as FIRDA, PLEDs or epileptiform discharges. Simultaneous EEG recording as well as impeccable technique are essential in proper recording of TBM, particularly as it can generate new forms of artifact.

The neurophysiological aspects of electrical injuries.

Neurologic and psychologic studies were done on 16 victims of alternate current electrical injuries. The patients were followed for a period of over 5 years. The findings point to a stereotyped generalized cerebral dysfunction, resulting in depression, divorce, unemployment as well as a high incidence of atypical seizures (atonic and myoclonic seizures).
