How many protein coding genes in human genome?5 answersThe estimated number of protein-coding genes in the human genome has been reduced to fewer than 20,000. A recent genome-wide effort utilizing single-cell transcriptomics data from various human tissues and organs has led to the annotation of all protein-coding genes, providing insights into their functions and spatial distributions across different cell types. However, there is still some disagreement in the annotation of approximately 2000 genes, which can be classified as protein-coding, noncoding, or pseudogenes, highlighting the complexity of gene annotation. The ongoing advancements in technology, such as high-throughput RNA sequencing, have significantly contributed to the identification and annotation of protein-coding genes in the human genome, although challenges remain in achieving a universal annotation standard for all medically significant genes.
Can you find any studies that long-read RNA sequencing in olfactory system?3 answersLong-read RNA sequencing has been used in various studies to explore different biological processes. However, none of the abstracts provided specifically mention the use of long-read RNA sequencing in the olfactory system. Therefore, there are no studies found in the provided abstracts that specifically focus on long-read RNA sequencing in the olfactory system.
How does our olfactory memory work?5 answersOur olfactory memory works by encoding and retaining sequences of sensory stimuli in working memory. This involves maintaining each sequence item in an active and discriminable state while preserving their temporal context. Nested neural oscillations, specifically the theta rhythm, play a crucial role in coordinating this process in the human brain. The anterior olfactory nucleus (AON) detects the coincidence of inputs from the olfactory bulb and the hippocampus, generating patterns of activity reflective of episodic odor engrams. The olfactory system, particularly the olfactory bulb, exhibits intrinsic plasticity that underlies both one-trial and cumulative odor learning, making it a valuable system for studying the cellular mechanisms of memory. Olfactory habituation induced at different timescales is mediated by different neural mechanisms, with short-timescale habituation occurring within the anterior piriform cortex and long-timescale habituation involving the olfactory bulbs. Olfactory memory encoding and retrieval are influenced by semantic processes, emotion, cross-modal integration, and contextual cues.
Theory about olfactory??5 answersThe olfactory system faces complex problems in dealing with odorant signals. Odors are multidimensional and variable, but the system can classify and identify them well. One proposed solution is a dynamic architecture that imposes a dynamic format on odor codes. This architecture creates a large coding space for odor representations and optimizes their distribution within it. Slow non-periodic processes help with decorrelation, while fast oscillations allow for sparsening and feature binding. Humans and other mammals perceive odors through a large family of olfactory receptors. Each odorant activates distinct combinations of receptors, generating a vast array of combinatorial receptor codes. Sensory neurons in the nose express only one receptor type each and connect to the olfactory bulb in a spatially organized manner. The olfactory bulb then transforms receptor inputs, generating a different sensory map that may integrate inputs from combinations of receptors. The olfactory system is an appropriate model for studying neuronal physiology, from development to neural network remodeling. Histochemistry techniques have been instrumental in understanding the morphological and physiological aspects of the olfactory system, such as the use of Olfactory Marker Protein staining and thymidine analogues to study neurogenesis. The capacity to form olfactory images has received less attention than visual and auditory images, and the evidence for this ability is inconsistent.
