Background: General anaesthesia causes decrease in both sympathetic & parasympathetic tone. Heart Rate variability (HRV) provides a powerful means of observing the interplay between sympathetic and parasympathetic nervous system. Reduced heart rate variability has been used as a marker of reduced vagal activity and is a valuable non-invasive tool i...

Brain Stem Auditory Evoked Potentials (BAEP) are potentials recorded from ear and vertex in response to brief auditory stimulation to asses conduction through the auditory pathway upto the level of midbrain. BAEP comprises of five or more waves within ten milliseconds of the stimulus and three interpeak latencies. Each individual wave and interpeak...

Obesity is a risk factor for type 2 diabetes mellitus. Insulin resistance is associated with visceral subcutaneous fat content. Neck circumference (NC) is a marker of upper body subcutaneous adipose tissue distribution. The aim of this study is to compare NC in diabetics and non-diabetics and to correlate NC with other anthropometric measures. A cr...

Diabetes Mellitus (DM) has detrimental effects on the various organs of our body includ-ing peripheral nervous system, which are widely accepted. However, not much research is done on understanding the central nervous system (CNS) abnormalities in DM. Visual evoked potential (VEP) is a non-invasive neurophysiological examination that detects early...
