Morphogenesis of the lateral geniculate nucleus in primates
The lateral geniculate nucleus (LGN) is the part of the mammalian visual system that relays information from the eye to the cerebral cortex. In the rhesus macaque monkey, the LGN exhibits an intricate lamination pattern, which changes midway through the nucleus at a point coincident with small gaps …

Cells, circuits, and development of the mouse lateral geniculate nucleus
… manipulation. Within the visual thalamus, the lateral geniculate nucleus (LGN) is divided into three distinct regions: ventral LGN (vLGN), dorsal LGN (dLGN), and the intergeniculate leaflet (IGL). Previous studies have characterized the cytoarchitecture and circuitry of dLGN, which is crucial …

Three Dimensional Organisation of the Adult Mouse dorsal Lateral Geniculate Nucleus
The dLGN (dorsal Lateral Geniculate Nucleus) is the gateway to cortical processing for visual information encoded by RGCs (retinal ganglion cells). Owing to advances in genetic manipulations, the mouse is increasingly the model system of choice for understanding the function and organisation of the …

The development, cytoarchitecture, and circuitry of the ventral lateral geniculate nucleus
… innervated by this retinal input are the dorsal lateral geniculate nucleus (dLGN) and ventral lateral geniculate nucleus (vLGN), both of which reside in the thalamus. The dLGN is well-studied and known to be important for classical image‐forming vision. The vLGN, on the other hand, is associated …

Circuit Development in the Dorsal Lateral Geniculate Nucleus (dLGN) of the Mouse.
… best understood sensory systems and the dorsal lateral geniculate nucleus (dLGN) of the mouse has emerged as a model for investigating the cellular and molecular mechanisms underlying the development and activity-dependent refinement of sensory connections. Thalamic organization is highly …

Postnatal development of brainstem cholinergic inputs to the dorsal lateral geniculate nucleus of the domesticated ferret, Mustela putorius furo
The ferret dorsal lateral geniculate nucleus (dLGN) undergoes two periods of retinal afferent segregation during postnatal development. The first establishes the eye-specific laminae, A and A 1, and the second establishes ON/OFF sublaminae within laminae A and At. In contrast to eyespecific …

DEVELOPMENTAL REMODELING OF RELAY CELLS IN THE DORSAL LATERAL GENICULATE NUCLEUS (dLGN) OF THE MOUSE AND THE ROLE OF RETINAL INNERVATION
The dorsal lateral geniculate nucleus (dLGN) has become an important model for studying many aspects of visual system development. To date, studies have focused on the development of retinal projections and the role of activity in shaping the pattern of synaptic connections made with …

Dependence of Visuomotor Behavior on Individual Layers of the Cat Lateral Geniculate Nucleus in the Normal Brain and Following Recovery From Destruction of Individual Layers
… understand the ways individual layers of the cat lateral geniculate nucleus (LGN) contribute to visuomotor behavior. This thesis has two main outcomes. First, the normal contribution of dorsal and ventral layers of the LGN to visuomotor behavior parallels their contributions to cortical activity, …

Structural dynamics and synaptic development in the visual system
… anatomical plasticity in the developing ferret lateral geniculate nucleus. Each of these studies focus specifically on the interactions between neuronal structure and function, principally at the level of synaptic contacts. The conclusions of this thesis are that structure and function are …

Characterization of the Role of R7-RGS Proteins in Mammalian Retina and Vision
… of R7-RGS/R7BP complexes in the dorsal lateral geniculate nucleus (dLGN), iii) characterization of blockade of RGS regulation of Gi2 and Go subunits on outer retina function, and iv) preliminary analysis of the effect of RGS6 ablation on vision. In part i), we found that R7BP is …

Effects of Reticular Activation on Long-Term Depression in Primary Visual Cortex of the Long-Evans Rat
… urethane anesthetized rats. LFS applied to the lateral geniculate nucleus resulted in LTD of field postsynaptic potentials (fPSPs) recorded in the primary visual cortex (V1). Pairing LFS with stimulation of the brainstem (pedunculopontine) reticular formation resulted in the appearance of …

Identification and functional characterization of two patterning genes, Zic4 and Ten_m3, in topographic map formation of the visual pathway
… expressed in gradients of the developing retina, lateral geniculate nucleus (LGN) and primary visual cortex (V 1). Mice lacking Zic4 exhibited a deficit in eye-specific patterning to the thalamus that was complementary to the phenotype seen in mice lacking Tenm3, a type II homophilic transmembrane …

Mechanisms underlying retinogeniculate synapse formation in mouse visual thalamus
Retinogeniculate (RG) synapses connect retinal ganglion cells to the thalamic relay cells of the dorsal lateral geniculate nucleus (dLGN). They are critical for regulating the flow of visual information from retina to primary visual cortex (V1). RG synapses in dLGN are uniquely larger and stronger …
