INTRODUCTION Response latencies of cortical neurons are not inexorably linked to response magnitude (Oram and Perrett 1992; Gawne et al 1996). The response latency of striate cortical neurons is heavily influenced by contrast whereas changes in response magnitude induced by changes in stimulus configuration (orientation) have relatively less effect on response latency. LGN neurons show increase...
Background: Increase in mobile phone users cause extensive consideration of researchers to biological effects of mobile phone waves. As the mobile set, is held near the ear and temporal lobe, and whereas distance of antenna from the inner ear is few centimeters, this study is the first research in our country to assess potential changes in auditory brain stem response of rabbit after exposure...
To evaluate the medicolegal relevance of middle latency responses for objectively approximating frequency-specific hearing levels in subjects with occupational hearing loss, we compared the middle latency response with the cortical response in 22 reliable subjects who had noise-induced hearing loss and were submitting claims for compensation and 21 subjects who had noise-induced hearing loss bu...
Single retinal ganglion cell's (RGCs) response properties, such as spike count and response latency, are known to encode some features of visual stimuli. On the other hand, neuronal response can be modulated by dopamine (DA), an important endogenous neuromodulator in the retina. In the present study, we investigated the effects of DA on the spike count and the response latency of bullfrog ON-OF...
