Evolution of olfactory receptors in birds [PDF]
, 2023 Olfaction is an evolutionary ancient sensation, and is the perception and interpretation of chemical stimuli from surrounding air or water. Olfaction is an essential sensory modality for nearly all animals, and is used to define territories, to identify ...

Advanced Science, EarlyView.This study reveals that Alzheimer's disease–linked APP expression in bone‐forming cells drives skull bone marrow remodeling and alters its vascular connections to the brain. These changes disrupt immune cell trafficking, cerebral blood flow, and cognition. Targeting bone marrow macrophages restores brain function, highlighting a previously unrecognized

Transposition and Intermingling of Galphai2 and Galphao afferences into single vomeronasal glomeruli in the Madagascan lesser Tenrec Echinops telfairi. [PDF]
, 2009 The vomeronasal system (VNS) mediates pheromonal communication in mammals. From the vomeronasal organ, two populations of sensory neurons, expressing either Galphai2 or Galphao proteins, send projections that end in glomeruli distributed either at the ...

Neuromorphic Near‐Sensor and In‐Sensor Computing Enabled by Next‐Generation Material‐Based Sensors
Advanced Science, EarlyView.This Review presents a structural framework that classifies neuromorphic sensing into near‐sensor and in‐sensor architectures, clarifying physical coupling between sensing and computation. The framework connects neural and synaptic device functions with recent advances in optical, mechanical, and chemical sensing, compares energy consumption and ...

The olfactory system as the gateway to the neural correlates of consciousness
Frontiers in Psychology, 2014 How consciousness is generated by the nervous system remains one of the greatest mysteries in science. Investigators from diverse fields have begun to unravel this puzzle by contrasting conscious and unconscious processes.

Underlying Mathematics in Diversification of Human Olfactory Receptors in Different Loci [PDF]
, 2010 As per conservative estimate, approximately (51-105) Olfactory Receptors (ORs) loci are present in human genome occurring in clusters. These clusters are apparently unevenly spread as mosaics over 21 pair of human chromosomes.

Photonic‐Enabled Energy‐Efficient Transparent Neuromorphic Computing Devices: A Review
Advanced Science, EarlyView.Transparent photonic neuromorphic computing devices merge optics and brain‐inspired computing to overcome von Neumann bottlenecks with ultrafast, low‐energy processing. By exploiting transparent oxides, 2D materials, phase‐change materials, and hybrid heterostructures, these platforms enable photonic synapses, memory, and logic for see‐through edge ...

Olfaction in the Colorado beetle at the onset of host plant selection [PDF]
, 1979 Long-range olfactory orientation of the adult Colorado beetle was studied in a low- speed wind tunnel. The odour of fully grown potato plants elicits an upwind locomotory response in Colorado beetles (odour-conditioned positive anemotaxis), and increases

Differing phagocytic capacities of accessory and main olfactory ensheathing cells and the implication for olfactory glia transplantation therapies [PDF]
, 2015 The rodent olfactory systems comprise the main olfactory system for the detection of odours and the accessory olfactory system which detects pheromones.

Advanced Science, EarlyView.This study demonstrates a Bi2WO6/SrBi2Ta2O9 heterojunction where light‐driven ferroelectric polarization reversal couples with persistent photoconductivity, enabling exclusive NO2 selective room‐temperature sensing. The device achieves a two‐order‐of‐magnitude sensitivity enhancement over an unpolarized device, a sub‐ppb detection limit, and robust ...
