Background: Epilepsy surgery has become a successful treatment option for patients with drug-resistant epilepsies. Objectives: This study aimed to assess temporal lobe epilepsy (TLE) surgery outcome and its association with epilepsy duration, the presence of pre-surgical generalized tonic-clonic seizure (GTCS), and brain MRI findings. Materials & Methods: This retrospective study was perfo...

To investigate the spatial and temporal frequency tunings for stereopsis, we measured the contrast sensitivity for depth discrimination with variable spatiotemporal frequencies and disparities using drifting sinusoidal gratings. The results showed that the contrast sensitivity changed with the stimulus disparity and the disparity tuning function varied with the spatial frequency. The disparity ...

Spatiotemporal frequency responses were measured at different levels of light adaptation for cat X and Y retinal ganglion cells. Stationary sinusoidal luminance gratings whose contrast was modulated sinusoidally in time or drifting gratings were used as stimuli. Under photopic illumination, when the spatial frequency was held constant at or above its optimum value, an X cell's responsivity was ...

Behavioral and neurophysiological studies in macaque monkeys suggest a role of the inferior temporal cortex in pattern discrimination and visual memory. To determine whether this cortical area is also involved in human short-term visual memory, we measured spatial frequency discrimination thresholds for sequentially presented stimuli in 17 patients with unilateral, postoperative focal damage to...

There are neurons in the cortex in the anterior part of the superior temporal sulcus of the macaque monkey with visual responses selective for faces. One aim of the present study was to analyze further the information which leads them to respond, by measuring their responses to parametrically filtered stimuli. The responses of 32 such single neurons were measured to faces which were digitized, ...

The effect of off-frequency energy on temporal integration measurements was investigated. Temporal integration functions for unfiltered and high pass filtered sinusoids of 20 and 200 msec duration and 1 msec rise-fall times were obtained from 4 normal hearing subjects and 4 subjects with high frequency, cochlear hearing impairments. Independent OF filtering, normal hearing subjects produced int...

background and aim: tinnitus is a distressing symptom for which few treatments exist. low-frequency repetitive transcranial magnetic stimulation (rtms) of the temporal cortex has been proposed as a treatment for chronic tinnitus. this study determined relationship between psychoacoustic parameters such as loudness and frequency of tinnitus and outcome with rtms treatment. methods: twenty six pa...
