Peripheral olfactory organ
WebFeb 15, 2002 · The peripheral olfactory system is able to recover after injury, i.e., the olfactory epithelium reconstitutes, the olfactory nerve regenerates, and the olfactory bulb is reinnervated, with a facility that is unique within the mammalian nervous system. WebDec 21, 2010 · We also know that olfactory sensory neurons in both main and accessory regions of the peripheral olfactory organ project to the medial OB . This suggests that the medial OB might be involved in generating motor behavior and take part in an olfactory-locomotor pathway irrespective of the type of odor molecules that are eliciting the …

WebOlfactory Organs. The secondary olfactory organs, paired maxillary palpae (singular palpus) are located ventral to the antennae and contain approximately 120 ORNs each, innervating multiporous sensilla. ... Ontogenetically, the peripheral olfactory organ is the first chemosensory organ to develop in fish, preceding the gustatory. ... WebOlfactory organs Olfactory perception in mosquitoes and other insects starts from their peripheral olfactory organs. These are traditionally defined by the expression of olfactory receptors (see the “ Olfactory receptors ” section below), neuronal responses and contribution to behavioural responses to airborne odorants.
WebNov 27, 2024 · The peripheral olfactory system comprises two separate olfactory epithelia (OE) located on each side of the head, halfway between the mouth and the eye. Each OE extends a short nerve, composed of olfactory sensory neuron (OSN) axons, to the olfactory bulb (OB) of the forebrain (telencephalon; Tel). WebThe peripheral part is formed by ganglia, and the cranial and spinal nerves. Fig. 2: Encephalon ... The olfactory sacs are paired organs located in the anterior dorsal region of the head. They communicate to the outside by means of a pair of double apertures called nares or nostrils (Fig. 3). Water enters through the front nostril and exits ...
WebThese ganglia are the cell bodies of neurons with axons that are sensory endings in the periphery, such as in the skin, and that extend into the CNS through the dorsal nerve root. The ganglion is an enlargement of the nerve root. Under microscopic inspection, it can be seen to include the cell bodies of the neurons, as well as bundles of fibers ...

WebIn olfactory perception, the peripheral organ—olfactory epithelium (OE) projects axons into the olfactory relay station—olfactory bulb (OB). The olfactory information encoded in the neural activity is recorded from both OE and OB simultaneously using flexible neural electrodes. Results reveal that spontaneous slow oscillations (<12 Hz) in ...
WebDec 21, 2024 · The zebrafish olfactory epithelium develops from a horseshoe-shaped pool of neural progenitors located at the boundary between the anterior neural plate and flanking non-neural ectoderm ( Miyasaka et al., 2013 ).
