Olfactory 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.
متن کاملAnterior Olfactory Nucleus
Characteristics The olfactory system is highly developed in vertebrates, particularly in “macrosmic” mammals (such as many rodents) where olfaction is the primary sensory system used to navigate in the world. As olfactory ability has evolved, there has been a concurrent increase in the size and complexity of cortical structures dedicated to encoding and deciphering olfactory information (▶corti...
متن کاملSynaptic integration of olfactory information in mouse anterior olfactory nucleus.
Individual odorants activate only a small fraction of mitral cells in the mouse main olfactory bulb (MOB). Odor mixtures are represented by a combination of activated mitral cells, forming reproducible activation maps in the olfactory bulb. However, how the activation of a cohort of narrowly tuned mitral cells by odor mixtures is read out synaptically by neurons in higher-level olfactory struct...
متن کاملTopographic Organization of Hippocampal Inputs to the Anterior Olfactory Nucleus
Top-down processes conveying contextual information play a major role in shaping odor representations within the olfactory system, yet the underlying mechanisms are poorly understood. The hippocampus (HPC) is a major source of olfactory top-down modulation, providing direct excitatory inputs to the anterior olfactory nucleus (AON). However, HPC-AON projections remain uncharacterized. In an effo...
متن کاملCytological organization of the alpha component of the anterior olfactory nucleus and olfactory limbus
This study describes the microscopic organization of a wedge-shaped area at the intersection of the main (MOB) and accessory olfactory bulbs (AOBs), or olfactory limbus (OL), and an additional component of the anterior olfactory nucleus or alpha AON that lies underneath of the AOB. The OL consists of a modified bulbar cortex bounded anteriorly by the MOB and posteriorly by the AOB. In Nissl-sta...
