Sensory neurons in the olfactory system develop from two different regions of the ectoderm, the olfactory placode and the cranial neural crest, whereas sensory neurons within the eye and ear develop from just one region.
A set of genes that are turned on only within time-limited windows—including genes encoding RNA binding molecules, let-7 microRNAs and IMP1—control developmental switches in stem cell properties between fetal development and adulthood.
Close examination of lanceolate mechanosensory complexes has revealed clues about the ways that sensory nerves detect the movement of hairs and shown than terminal Schwann cells are needed to maintain and regenerate these intricate structures.
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.
Contrary to the common belief that cognitive event-related potentials are generated by local activity within the cerebral cortex, it is shown that some of these potentials are modulated by subcortical inputs.
