Statistical Information About Hs

Statistical information about HS / HT & WDS Taking into consideration the fact that HS and WDS behaviours are different in form and can at times occur all together they are different also according to duration, strength, and energy. We have the following statistical figure for the above mentioned: Statistics

We can see from the graph that HS and WDS have high peaks in two (2) frequency intervals (low frequency up to 5Hz and high frequency up to 12-20Hz). HT has only high-frequency component (15-25Hz). In terms of behaviour it can be explained as follows: low-frequency component is conditioned by body movement, high-frequency component – by head movement. In case of HT energy depends mainly on highfrequency component as duration is too short. Depending upon animal species, drugs, and dosage different variations of these are possible, and also it is possible the behaviours to occur at the same time.
