Our eyes send different'images' of the outside world to the brain—an image of contours (line
drawing), a colour image (watercolour painting) or an image of moving objects (movie). This …

This review summarizes our current knowledge of primate including human retina focusing
on bipolar, amacrine and ganglion cells and their connectivity. We have two main …

As a more complete picture of the clinical phenotype of Parkinson's disease emerges, non-
motor symptoms have become increasingly studied. Prominent among these non-motor …

Psychology is of interest to academics from many fields, as well as to the thousands of
academic and clinical psychologists and general public who can't help but be interested in …

To understand a neural circuit requires knowledge of its connectivity. Here we report
measurements of functional connectivity between the input and ouput layers of the macaque …

Some fundamental principles of colour vision, deduced from perceptual studies, have been
understood for a long time. Physiological studies have confirmed the existence of three …

▪ Abstract Color vision starts with the absorption of light in the retinal cone photoreceptors,
which transduce electromagnetic energy into electrical voltages. These voltages are …

Synaptic interactions to extract information about wavelength, and thus color, begin in the
vertebrate retina with three classes of light-sensitive cells: rod photoreceptors at low light …

Color vision is essential for an animal's survival. It starts in the retina, where signals from
different photoreceptor types are locally compared by neural circuits. Mice, like most …

Visual symptoms are common in PD and PD dementia and include difficulty reading, double
vision, illusions, feelings of presence and passage, and complex visual hallucinations …
