There is a general impression that visually blind individuals show an exceptionally better perception of other sensory modalities such as hearing, touch and smell sensations. In this study, we intended to compare the mid-latency auditory evoked potential response (MLAEP) or Middle latency Response (MLR) to get an idea of the activity pattern of auditory thalamus and cortex between 30 visually h...

Conventional and maximum length sequence (MLS) middle latency response (MLR) procedures were compared across several parameters for control patients and patients with central nervous system lesions. There were similar findings for both populations and both types of MLR for the absolute latencies of Na and Pa waves. Middle latency waves were absent more often in the neurologic than control subje...

The slow wave (SW) component of the auditory brainstem response (ABR) was recorded in eight young adult subjects of both genders who had normal hearing sensitivity and who exhibited normal behavioral temporal integration (TI) functions. Test stimuli were 500- and 2000-Hz tone bursts, with rise and decay ramps of two periods, ranging in total duration from 2.5 msec to 44 msec. The responses appe...

The present study aims to evaluate the functional integrity of the auditory pathway in patients with diabetes taking metformin. A further aim is to assess its association with vitamin B12 deficiency induced by metformin. Thirty diabetics taking metformin and 30 age-matched non-diabetic controls were enrolled. Stimulus-related potentials and vitamin B12 levels were evaluated in all the subjects....

In this study omission evoked potentials (OEPs) were studied in rhythmic experts (n=12) and non-musicians (n=12). Trains of auditory stimuli were presented. Trials (n=90) contained five omissions and started with a random number of beats, thus making every first omission unpredictable. Participants had to tap along with the first beat after the fifth omission (n=90), thus determining timing-acc...

BACKGROUND & OBJECTIVES Each skeletal muscle is usually supplied by two or more nerve roots and if one nerve root is affected and the other is spared, the clinically used F wave minimum latency can still be normal. An F wave index was constructed taking into consideration the other parameters of the F wave such as persistence, chronodispersion, latency, arm-length to determine its usefulness in...
