Neuronal nonlinearity explains greater visual spatial resolution for darks than lights
Significance Light and dark stimuli are separately processed by ON and OFF channels in retina and thalamus. Although most textbooks assume that ON and OFF visual responses are relatively balancedExpand

Neuronal and Perceptual Differences in the Temporal Processing of Darks and Lights
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. Here, we demonstrateExpand

Faster Thalamocortical Processing for Dark than Light Visual Targets
ON and OFF visual pathways originate in the retina at the synapse between photoreceptor and bipolar cells. OFF bipolar cells are shorter in length and use receptors with faster kinetics than ONExpand

Response Properties of Local Field Potentials and Neighboring Single Neurons in Awake Primary Visual Cortex
Recordings from local field potentials (LFPs) are becoming increasingly common in research and clinical applications, but we still have a poor understanding of how LFP stimulus selectivity originatesExpand

COLUMNAR ORGANIZATION OF SPATIAL PHASE IN VISUAL CORTEX
Images are processed in the primary visual cortex by neurons that encode different stimulus orientations and spatial phases. In primates and carnivores, neighboring cortical neurons share similarExpand

The Effects of Fifa 2015 Computer Games on Changes in Cognitive, Hormonal and Brain Waves Functions of Young Men Volunteers
Introduction: Computer games have attracted remarkable attentions in general publics with different cultures and their effects are subject of research by cognitive neuroscientists. In the presentExpand

Behavioral and electrophysiological studies of chronic oral administration of L-type calcium channel blocker verapamil on learning and memory in rats
It has been shown that L-type voltage dependent calcium channels (VDCCs) have important role in learning and memory. In vivo and in vitro electrophysiological recordings of hippocampal neurons haveExpand

Effects of GABAergic inhibition on neocortical long-term potentiation in the chronically prepared rat
Long-term potentiation (LTP) is a form of activity-dependent synaptic plasticity that is a candidate cellular mechanism for some forms of learning and memory. Although GABAergic synaptic inhibitionExpand

The role of GABAergic transmission in the dentate gyrus on acquisition, consolidation and retrieval of an inhibitory avoidance learning and memory task in the rat
The hippocampal GABAergic interneurons are responsible for controlling the input of large principal cell populations, and they thereby determine the oscillatory discharge patterns and synapticExpand

NMDA receptors of dorsal hippocampus are involved in the acquisition, but not in the expression of morphine-induced place preference.
In the present study, involvement of the N-methyl-d-aspartate (NMDA) receptors of the CA1 region of dorsal hippocampus (intra-CA1) in the acquisition or expression of morphine-induced conditionedExpand
