Long non-coding RNAs and their significance in human diseases
Protein-coding genes account for only a small fraction of the human genome and most of the genomic sequences are transcriptionally silent, but recent observations indicate significant functional elements, including non-coding protein transcripts in the human genome. Long non-coding RNAs (lncRNAs) have been defined as transcripts of >200 nucleotides without protein-coding capacity that perform t...
متن کاملCombinatorial On/off Model for Olfactory Coding
We present a model for olfactory coding based on spatial representation of glomerular responses. In this model distinct odorants activate specific subsets of glomeruli, dependent upon the odorant's chemical identity and concentration. The glomerular response specificities are understood statistically, based on experimentally measured distributions of detection thresholds. A simple version of th...
متن کاملOlfactory Coding: When Smells Collide
Brain responses can significantly outlast sensory stimuli leading to potential ambiguity when responses overlap. Recent studies of locust olfaction found that the responses of individual second order projection neurons depend markedly on the previous few seconds' stimulus history; the population response, however, still conveys information about both temporal structure and odour identity.
متن کاملOlfactory coding: Revealing intrinsic representations of odors
Recent studies have applied optical imaging of intrinsic signals to the rodent olfactory system, providing a unique view of how odorous molecules are represented in the central nervous system.
