Abstract

Sensory information is encoded both in space and in time. Spatial encoding is based on the identity of activated receptors, while temporal encoding is based on the timing of activation. In order to generate accurate internal representations of the external world, the brain must decode both types of encoded information, even when processing stationary stimuli. We review here evidence in support of a parallel processing scheme for spatially and temporally encoded information in the tactile system and discuss the advantages and limitations of sensory-derived temporal coding in both the tactile and visual systems. Based on a large body of data, we propose a dynamic theory for vision, which avoids the impediments of previous dynamic theories.

Central organization of the electrosensory system in the paddlefish (Polyodon spathula).

The central connections of the electrosensory system were studied in the paddlefish Polyodon spathula by injecting biotinylated dextran amines into the dorsal octavolateral nucleus (DON), the cerebellum, and the mesencephalic tectum. The sole target of primary electrosensory fibers is the ipsilateral dorsal octavolateral nucleus. The principal neurons ascending from this nucleus project to the torus semicircularis, the lateral mesencephalic nucleus, and the mesencephalic tectum. The mesencephalic tectum projects back to the nucleus preeminentialis, which, in turn, projects to the cerebellar auricles and to the DON. The auricles are the main source of parallel fibers in the cerebellar crest ventral to the DON. The DON also receives input from the contralateral DON. These descending feedback loops are very similar to those of other electrosensory fishes. However, the paddlefish is unique in having three mesencephalic targets of electrosensory information. It is the only bony fish known to have extensive projections directly to the mesencephalic tectum and to a lateral mesencephalic nucleus in addition to the torus semicircularis.

Role of retinal afferents in regulating growth and shape of the lateral geniculate nucleus.

Segregated binocular maps in the dorsal lateral geniculate nucleus (LGN) develop from a stage where they initially overlap. Sophisticated computational models have been used to describe the dynamics of three-dimensional LGN shape changes that play a role in segregation. These models have revealed specific nuclear growth vectors associated with the process of ocular segregation in the LGN (Williams and Jeffery [2001] J Comp Neurol 430:332-342.). In this study, we use similar techniques to determine whether retinal innervation contributes to the dynamics of shape maturation in the ferret LGN. In this animal, 90% of the retinal innervation of the mature LGN comes from the contralateral eye. If one eye is removed before segregation, the projection from the remaining eye remains diffuse and nuclear growth is stunted. Here, we quantify this effect and show that removing the contralateral projection before segregation has a profound impact on LGN size but changes its ultimate shape by only 12%. The impact on shape on the other side of the brain where the ipsilateral projection is removed, which accounts for only 10% of its innervation in maturity, is less than 2%. Hence, retinal innervation plays a minor role in determining mature LGN shape. Although in both hemispheres, the ultimate shape of the nucleus is close to normal, removal of the larger projection disrupts normal growth vectors, with almost none being present in the 5 days after enucleation, when the normal nucleus expands markedly. Hence, the effect of enucleation is to delay shape maturation. Growth vectors absent after removal of the smaller projection are mainly confined to those in what would be the binocular region.

Abnormal positioning of granule cells alters afferent fiber distribution in the mouse fascia dentata: morphologic evidence from reeler, apolipoprotein E receptor 2-, and very low density lipoprotein receptor knockout mice.

The fascia dentata of the hippocampal formation is characterized by the nonoverlapping and lamina-specific termination of afferent fibers: entorhinal fibers terminate in the outer molecular layer and commissural/associational fibers terminate in the inner molecular layer. It has been proposed that this fiber lamination depends on the presence of the correct postsynaptic partner at the time of fiber ingrowth during development. Pioneer neurons that guide afferent fibers to their correct layers as well as signals located on granule cells have both been implicated. To study the role of granule cells for the lamina-specific ingrowth of afferents, the cyto- and fiberarchitecture of three mouse mutants (very low density lipoprotein receptor knockout mouse, apolipoprotein E receptor 2 knockout mouse, and reeler mouse) that show different degrees of granule cell migration defects were analyzed. Anterograde tracing with Phaseolus vulgaris-leucoagglutinin was used to visualize the afferent fiber systems, and immunohistochemistry was used to determine the position of their putative target cells. In controls, granule cells are packed in a single layer. This laminar organization is mildly altered in very low density lipoprotein receptor knockout mice, moderately disturbed in apolipoprotein E receptor 2 knockout mice, and severely disrupted in reeler mice. These changes in granule cell distribution are mirrored by the distribution of commissural fibers. In contrast, changes in granule cell distribution do not severely affect the laminar termination of entorhinal fibers. These data provide further evidence for a role of granule cells in the laminar termination of commissural/associational afferents to the fascia dentata.
