Spatial frequency bandwidth of surround suppression tuning curves.
The contrast detection threshold of a grating located in the periphery is increased if a surrounding grating of the same frequency and orientation is present. This inhibition between center and surround has been termed surround suppression. In this work we measured the spatial frequency bandwidth of surround suppression in the periphery for different spatial frequencies (0.5, 1.1, 3, and 5 cycl...
متن کاملLow-Frequency Envelope Sensitivity Produces Asymmetric Binaural Tuning Curves
Neurons in the auditory midbrain are sensitive to differences in the timing of sounds at the two ears--an important sound localization cue. We used broadband noise stimuli to investigate the interaural-delay sensitivity of low-frequency neurons in two midbrain nuclei: the inferior colliculus (IC) and the dorsal nucleus of the lateral lemniscus. Noise-delay functions showed asymmetries not predi...
متن کاملFrequency of Human Platelet Antigens (HPA-2/3/5) Polymorphism in Iranians Evaluated by RFLP-PCR
ackground: Knowing the human platelet antigens (HPA) and genes frequency in different populations is important not only for population studies but also for clinical transfusion practice. HPA genes frequency in Iran is not evaluated, so we investigated the HPA-2, HPA-3, and HPA-5 frequency and their polymorphism. Materials and Methods: DNA from 120 Iranians (99 Iranian blood donors and 21 patie...
متن کاملSpatial frequency tuning studies: weighting as a prerequisite for describing psychometric curves by probability summation.
The visibility of sine-wave gratings was determined as a function of their width and modulation depth. The psychometric curves were described by probability summation. resulting in weighting functions which under certain conditions indicate the existence of tuning. i.e. a maximum sensitivity outside the fovea at an eccentricity inversely proportional to the spatial frequency. The disagreement i...
متن کاملLow-Frequency Envelope Sensitivity Produces Asymmetric Binaural Tuning Curves Running Title: Low-Frequency Binaural Envelope Sensitivity
Neurons in the auditory midbrain are sensitive to differences in the timing of sounds at the two ears—an important sound localization cue. We used broadband noise stimuli to investigate the interaural-delay sensitivity of low-frequency neurons in two midbrain nuclei: the inferior colliculus (IC) and the dorsal nucleus of the lateral lemniscus (DNLL). Noise delay functions showed asymmetries not...
