Electro Physiological Test

Reconstructing anatomy from electro-physiological data

Here we show how it is possible to make estimates of brain structure based on MEG data. We do this by reconstructing functional estimates onto distorted cortical manifolds parameterised in terms of their spherical harmonics. We demonstrate that both empirical and simulated MEG data give rise to consistent and plausible anatomical estimates. Importantly, the estimation of structure from MEG data...

An electro-physiological device to assess status of vitreous transparency.

INTRODUCTION Evaluation of optical media is important in ophthalmic practice. OBJECTIVE to design and tryout an electro-physiological device in order to assess the transparency of the vitreous. MATERIALS AND METHODS A media-meter was designed where a light sensitive sensor was placed on the cornea and adjoining sclera during the process of trans-illumination. The trans-corneal (TC) and tran...

Electro-Physiological Approaches to Monitoring Neuro- Degenerative Diseases

The Physiological Mechanism behind the Talk Test

The Talk Test (TT) is a very simple marker of exercise intensity, which has been shown to be a useful surrogate of the ventilatory (VT) and respiratory compensation (RCT) thresholds. The purpose of this study was to evaluate a potential mechanism behind the TT. Healthy, college-aged subjects (n=20) performed a maximal and two sub-maximal cycle ergometer tests. The two submaximal tests were perf...

Xerosis meter-an electro-physiological device for quick screening of dry eyes.

AIM to study the role of'Xerosis Meter' in screening of dry eye cases in a large population and compare its results with Schirmer's test and tear break-up time. MATERIALS AND METHOD in a cross sectional study with a control group dry eye was evaluated with Xerosis Meter, Schirmer test and tear film break-up time (TBUT). Cases included in the study were divided into two groups. Group I (Contro...
