Visual processing starts at the retina of the eye, and signals are then transferred primarily to
the visual cortex and the tectum. In the retina, multiple neural networks encode different …

Gamma-band activity, peaking around 30–100 Hz in the local field potential's power
spectrum, has been found and intensively studied in many brain regions. Although gamma …

Gamma rhythms in many brain regions, including the primary visual cortex (V1), are thought
to play a role in information processing. Here, we report a surprising finding of 3 narrowband …

Pressures for survival make sensory circuits adapted to a species' natural habitat and its
behavioral challenges. Thus, to advance our understanding of the visual system, it is …

Studying the laminar pattern of neural activity is crucial for understanding the processing of
neural signals in the cerebral cortex. We measured neural population activity [multiunit spike …

Astronomers and physicists noticed centuries ago that visual spatial resolution is higher for
dark than light stimuli, but the neuronal mechanisms for this perceptual asymmetry remain …

The integration of direct bottom-up inputs with contextual information is a core feature of
neocortical circuits. In area V1, neurons may reduce their firing rates when their receptive …

Human vision processes light and dark stimuli in visual scenes with separate ON and OFF
neuronal pathways. In nature, stimuli lighter or darker than their local surround have different …

Visual information is mediated by two major thalamic pathways that signal light decrements
(OFF) and increments (ON) in visual scenes, the OFF pathway being faster than the ON …

Cortical inhibition plays an important role in information processing in the brain. However,
the mechanisms by which inhibition and excitation are coordinated to generate functions in …
