Spindle oscillations are generated in the dorsal thalamus and modulated by the thalamic reticular nucleus [PDF]

, 2008
Spindle waves occur during the early stage of slow wave sleep and are thought to arise in the thalamic reticular nucleus (TRN), causing inhibitory postsynaptic potential spindle-like oscillations in the dorsal thalamus that are propagated to the cortex ...

Functional representation of vision within the mind: A visual consciousness model based in 3D default space [PDF]

, 2015
The human eyes and brain, which have finite boundaries, create a ‘‘virtual’’ space within our central nervous system that interprets and perceives a space that appears boundless and infinite.

Modeling the Possible Influences of Eye Movements on the Refinement of Cortical Direction Selectivity [PDF]

, 2004
The second-order statistics of neural activity was examined in a model of the cat LGN and V1 during free-viewing of natural images. In the model, the specific patterns of thalamocortical activity required for a Bebbian maturation of direction-selective ...

Synapses and dendritic spines are eliminated in the primary visual cortex of mice subjected to chronic intraocular pressure elevation

Neural Regeneration Research
Synaptic plasticity is essential for maintaining neuronal function in the central nervous system and serves as a critical indicator of the effects of neurodegenerative disease.

Modeling Reverse-Phi Motion-Selective Neurons in Cortex: Double Synaptic-Veto Mechanism [PDF]

, 2003
Reverse-phi motion is the illusory reversal of perceived direction of movement when the stimulus contrast is reversed in successive frames. Livingstone, Tsao, and Conway (2000) showed that direction-selective cells in striate cortex of the alert macaque ...

Attentional load and sensory competition in human vision: Modulation of fMRI responses by load fixation during task-irrelevant stimulation in the peripheral visual field. [PDF]

, 2005
Perceptual suppression of distractors may depend on both endogenous and exogenous factors, such as attentional load of the current task and sensory competition among simultaneous stimuli, respectively. We used functional magnetic resonance imaging (fMRI)

[Lateral geniculate bodies in humans--analysis of development].

Klinika oczna, 1990
Macroscopial and microscopial analysis of development of the lateral geniculate bodies was performed in 32 human brains of persons of various age. Their presence was revealed in all the cases. Observation of the histopahtological specimen showed---in contradistinction to the results of experimental animal investigations found in the world's literature--
