Chromatic and luminance signals in visual memory.
The efficiency of chromatic and luminance signals was studied in a set of tasks requiring the discrimination of two colors. Discrimination was measured around an adapting achromatic light and a number of other points in a three-dimensional color space. As a baseline, discrimination thresholds were measured under conditions permitting a side-by-side comparison of stimuli in space or time. For th...
متن کاملDelayed cone-opponent signals in the luminance pathway.
Cone signals in the luminance or achromatic pathway were investigated by measuring how the perceptual timing of M- or L-cone-detected flicker depended on temporal frequency and chromatic adaptation. Relative timings were measured, as a function of temporal frequency, by superimposing M- or L-cone-isolating flicker on "equichromatic" flicker (flicker of the same wavelength as the background) and...
متن کاملFlicker ERGs representing chromaticity and luminance signals.
PURPOSE To test the hypothesis that electroretinograms (ERGs) reflect luminance activity when measured at high temporal frequencies and chromatic activity when measured near 12 Hz. METHODS The authors measured the responses to stimuli in which the output of red and green light-emitting diodes was modulated in counterphase at different ratios, varying the luminance content in the stimulus whil...
متن کاملDiagnosis of Parkinson’s Disease in Human Using Voice Signals
A full investigation into the features extracted from voice signals of people with and without Parkinson’s disease was performed. A total of 31 people with and without the disease participated in the data collection phase. Their voice signals were recorded and processed. The relevant features were then extracted. A variety of feature selection methods have been utilized resulting in a good perf...
متن کاملAdaptive and aberrant reward prediction signals in the human brain
Theories of the positive symptoms of schizophrenia hypothesize a role for aberrant reinforcement signaling driven by dysregulated dopamine transmission. Recently, we provided evidence of aberrant reward learning in symptomatic, but not asymptomatic patients with schizophrenia, using a novel paradigm, the Salience Attribution Test (SAT). The SAT is a probabilistic reward learning game that emplo...
