Sensory enrichment creates a more columnar, less salt-and-pepper whisker map in somatosensory cortex, showing that impoverished experience contributes to intermixed tuning in rodent sensory maps.
The three-dimensional structures of 50 sensory cilia present in the head of the adult C. elegans hermaphrodite have been reconstructed to provide a foundation for investigations into the mechanisms by which the diversity of cilia structures is generated and how this structural diversity is related to specific sensory neuron functions.
Retinal ephrin-As gradients provide positional information, through retino-collicular map in the superior colliculus, for topographic alignment of cortico-collicular projections.
Individual granule cells within the cerebellum-the region of the brain that coordinates movement and supports the learning of new motor skills-receive both sensory and motor input streams: an arrangement that may help the brain to use feedback to fine-tune movement.
Human sensory neurons may not only bridge a critical gap between drug discovery and clinical trials, but force a re-evaluation of basic assumptions about the mechanisms controlling primary afferent excitability.
Systematic analysis of descending neuron anatomy reveals the basic functional map of descending sensory-motor pathways in flies and provides genetic tools for targeted interrogation of neural circuits.
The brain continues to represent individual fingers in primary somatosensory cortex decades after the amputation of a hand, indicating that cortical maps do not require ongoing sensory input from the body.
