Olfactory Receptors: Location and Structure

12.1K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

The eukaryotic nucleus is a double membrane-bound organelle that contains nearly all of the cell’s genetic material in the form of chromosomes. It is rightly called the “brain” of the cell as it shoulders the responsibility of responding to various physiological processes, stress, altered metabolic conditions, and other cellular signals. 
The nucleus contains many membrane-less subnuclear organelles or nuclear bodies, such as nucleoli, Cajal bodies, speckles,...

Assembly of Signaling Complexes

6.7K
Multiprotein signaling complexes are formed in a dynamic process involving protein-protein interactions at the cytoplasmic domain of transmembrane receptors or enzymatic and non-enzymatic proteins associated with the receptor. These complexes ensure the activation and propagation of intracellular signals that regulate cell functions.
Interaction domains in cell signaling
Interaction domains recognize exposed features of their binding partners containing post-translationally modified sequences,...

Area of Science:

  • Neuroscience
  • Cognitive Science
  • Spatial Navigation

Background:

  • The subiculum is a critical component of the brain's cognitive map system.
  • It interconnects with various brain regions involved in spatial processing and navigation.

Purpose of the Study:

  • To review evidence for the functional roles of the dorsal subiculum within the cognitive map.
  • To explore its potential role in encoding environmental structure versus transmitting spatial information.

Main Methods:

  • Literature review of existing studies on subiculum function.
  • Analysis of neuron tuning properties in relation to environmental features.

Main Results:

  • The dorsal subiculum is involved in integrating location, orientation, and boundary information.
  • Evidence suggests a role in transitioning spatial encoding into navigational actions.

Conclusions:

  • Subiculum neuron tuning to environmental features like boundaries, angles, and axes underlies the encoding of environmental shape.
  • This encoding is crucial for understanding path networks and guiding navigation.
