Abstract :

<p>&lt;p&gt;&amp;lt;p&amp;gt;&amp;amp;nbsp;The autonomic nervous system performs and regulates automatic bodily functions associated with eathing, heart rate, blood pressure, digestion, and the hormonal system. The autonomic nervous system itself has two parts: sympathetic and parasympathetic. The sympathetic and parasympathetic nervous systems initiate the stress and relaxation response, respectively. There is normally a balance maintained between the activities of the sympathetic and parasympathetic nervous systems. Reactivity of blood pressure to cold stress has been used as a measure of existing autonomic nervous system activity level by many authors. Autonomic nervous system activity is influenced by Reticular Activating System activity and vice-versa, activity of central nervous system can be studied in electroencephalogram so a relationship between cereal cortical electrical activity and cold pressor test reactivity of an individual is a possibility worth exploring. Purpose of study is to compare alpha wave appearance time in EEG in subjects hyper- reactor and normo-reactors to cold pressor test. The subjects comprised of both male and female 120 young medical students of age group 18 to 21 years and selected randomly. Alpha appearance time in EEG in hyper-reactors is significantly more when compared to normo-reactors at 0.001 level of probability.&amp;lt;/p&amp;gt;&lt;/p&gt;</p>
