Spatial attention enhances our ability to detect stimuli at restricted regions of the visual field.
This enhancement is thought to depend on the difficulty of the task being performed, but the …

Awake mammals are often inattentive in familiar environments, but must still respond
appropriately to relevant visual stimulation. Such "inattentive vision" has received little study, …

Thalamocortical conduction times are short, but layer 6 corticothalamic axons display an
enormous range of conduction times, some exceeding 40–50 ms. Here, we investigate (1) how …

The primary visual cortex of carnivores and primates is dominated by the OFF visual pathway
and responds more strongly to dark than light stimuli. Here, we demonstrate that this …

The effects of different EEG brain states on spontaneous firing of cortical populations are not
well understood. Such state shifts may occur frequently under natural conditions, and …

Sensory cortical neurons are highly sensitive to brain state, with many neurons showing
changes in spatial and/or temporal response properties and some neurons becoming virtually …

Extracellular recordings were obtained from two cell classes in layer 4 of the awake rabbit
primary visual cortex (V1): putative inhibitory interneurons [suspected inhibitory interneurons (…

We used spike-triggered current source-density analysis to examine axonal and postsynaptic
currents generated in the visual cortex of awake rabbits by spontaneous spikes of …

The spread of somatic spikes into dendritic trees has become central to models of dendritic
integrative properties and synaptic plasticity. However, backpropagating action potentials (…

Some cortical neurons receive highly selective thalamocortical (TC) input, but others do not.
Here, we examine connectivity of single thalamic neurons (lateral geniculate nucleus, LGN) …
