[A new method of analysis of impulse activity in brain neurons]

Investigation of impulse activity of hypothalamic neurons is of a great importance in attempt to connect the neuronal function with its activity. We have proposed an original method of analysis of background and temperature-induced impulse activity of thermosensitive neurons from frontal hypothalamus. In acute experiments on cats under ketamine anastasia neuronal activity was measured by glass microelectrode. Measurements of background neuronal activity was performed during 30 s, and post-stimulus activity was measured during 60 s. Computer program calculated the mean value of background activity. These results were used to create bar graph in the range +/- 100% with time interval 10%. It is suggested that the results of analysis of background activity of thermosensitive hypothalamic neurons allow interpret the characteristics of functions of hypothalamic neurons.
