EEG criteria for flying fitness applied by the German air force institute of aviation medicine.

A re-evaluation of EEGs of more than 1,000 applicants for flying training is presented. All EEG abnormalities were reevaluated by three EEG specialists. Out of 1,630 EEG records, 5.4% were classified as abnormal and, of these, 24 were found to have a bearing on flying qualification. SW-variants and paroxysms were cause for elimination in any case. This study led to the adoption of the following policy: Any subject showing EEG abnormalities, possibly requiring a permanent elimination, will undergo a second EEG by another examiner. In cases with EEG anomalies, a followup EEG is done with a concurrent sensory-motor performance test. This is supplemented by an evaluation of collateral cerebral circulation, using uni-and bilateral compression of the vertebral and carotid arteries. In cases without noticeable performance deficiencies another EEG is done a year later in order to exclude a progression of the EEG anomalies.

[Modelling of biological encoding mechanisms as a system with distributed parameters].

The encoder region in receptors and neurons is represented by the inhomogeneous origin of the axon. The axon diameter and the excitability are in fact space-dependent. For the analysis the soma is described by a system with concentrated parameters followed by an inhomogeneous axon. The membrane properties are approximated by the slightly modified Hodgkin-Huxley equations. The assumption that the space-dependence of the excitability originates in variations of the conductance value for sodium ions accounts for a number of experimental results. The influence of other membrane parameters upon the mechanism of impulse generation and transmission has also been analysed.
