Summary remarks It is evident that the bulbar EEG is a complex response which can be influenced by several methodological and stimulant variables. What EEG patterns tell us about actual behavior remains obscure. The bulbar EEG which is evoked by homestream water is not necessarily a reflection of olfactory memory. The evoked bulbar EEG also does not necessarily demonstrate the salmon has distinguished the home-water from another water in terms of migrational orientation. Despite lack of absolute specificity, a correlation between bulbar EEG and actual behavioral performance has been observed even though some non-home waters evoke responses similar to that of the home water. In general it has been found that the home water response can be distinguished from the response to other natural waters. Failure to obtain complete specificity may be due to a variety of variables which have been alluded to earlier in this section. Thus considering that the evoked EEG is a reflection of the integration of a diverse afferent input, further electrical and computer analyses may eventually permit the decoding of the EEG in terms of behavior. However, if the EEG proves to be more a quantitative rather than qualitative reflection of brain activity, relating EEG to behavior will prove to be of limited value. Since afferent responses in the olfactory bulb are influenced by impulses from higher brain centers, studies on centrifugal aspects during olfactory stimulation may be useful in gaining some qualitative understanding of the home water evoked EEG of the olfactory bulb.
