Receptors are sensitive to discrete stimuli and are often classified by both the systemic function and the location of the receptor.. Sensory receptors are found throughout our bodies, and sensory receptors that share a common location often share a common function. For example, sensory receptors in the retina are almost entirely photoreceptors. Our skin includes touch and temperature receptors, and our inner ears contain sensory mechanoreceptors designed for detecting vibrations caused by sound or used to maintain balance.. Force -sensitive mechanoreceptors provide an example of how the placement of a sensory receptor plays a role in how our brains process sensory inputs. While the cutaneous touch receptors found in the dermis and epidermis of our skin and the muscle spindles that detect stretch in skeletal muscle are both mechanoreceptors, they serve discrete functions.. In both cases, the mechanoreceptors detect physical forces that result from the movement of the local tissue, cutaneous ...

The somatic nervous system is traditionally considered a division within the peripheral nervous system. However, this misses an important point: somatic refers to a functional division, whereas peripheral refers to an anatomic division. The somatic nervous system is responsible for our conscious perception of the environment and for our voluntary responses to that perception by means of skeletal muscles. Peripheral sensory neurons receive input from environmental stimuli, but the neurons that produce motor responses originate in the central nervous system.. The distinction between the structures (i.e., anatomy) of the peripheral and central nervous systems and functions (i.e., physiology) of the somatic and autonomic systems can most easily be demonstrated through a simple reflex action. When you touch a hot stove, you pull your hand away. Sensory receptors in the skin sense extreme temperature and the early signs of tissue damage. This triggers an action potential, which travels along the ...

Bcl11a is expressed in both presynaptic sensory neurons and postsynaptic spinal target neurons (Fig. 1). We next asked whether Bcl11a is required for correct wiring, and if so, on which site. Central axons of sensory neurons were labeled at E16.5 with DiI. In the superficial dorsal horns of Brn4-Cre;Bcl11a mutants, the density of DiI-positive fibers was greatly reduced and the remaining fibers appeared disorganized. Only a few axons crossing the midline or located in a dorsolateral region of the dorsal horn were detectable by DiI labeling in mutants (Fig. 5A,B). TrkA (Ntrk1 - Mouse Genome Informatics) -positive nociceptive fibers preferentially terminate in the superficial dorsal horn. Immunohistological analysis with antibodies against TrkA or aquaporin 1, a water channel protein that is expressed by small-diameter nociceptive fibers (Oshio et al., 2006), invariably revealed almost complete loss of such fibers in the dorsal horn of Brn4-Cre;Bcl11a mutants (Fig. 5C-F). Similar results were ...

It is commonly observed that schooling fish are particularly in danger of being eaten if they are separated from the school.[4] Several anti-predator functions of fish schools have been proposed. One potential method by which fish schools might thwart predators is the predator confusion effect proposed and demonstrated by Milinski and Heller (1978).[25] This theory is based on the idea that it becomes difficult for predators to pick out individual prey from groups because the many moving targets create a sensory overload of the predators visual channel. Milinski and Hellers findings have been corroborated both in experiment[26][27] and computer simulations.[28][29] Shoaling fish are the same size and silvery, so it is difficult for a visually oriented predator to pick an individual out of a mass of twisting, flashing fish and then have enough time to grab its prey before it disappears into the shoal.[4] Schooling behaviour confuses the lateral line organ (LLO) as well as the electrosensory ...

Precise pattering of dendrites as well as axons is essential for correct wiring and function of neural circuits. In addition, dendrites from certain mature neurons change their shape in response to changes in the environment. We combine fly/mice genetics, imaging, and biochemical approaches to investigate the interplay between genetic and epigenetic control of dendrite morphogenesis in vivo, and deduce the functional importance of these regulatory systems in disease etiology. In particular, we focus our researches on the genetic and molecular regulation of dendrite pattering and plasticity in the Drosophila sensory circuits. In this talk, I first present how intrinsic and extrinsic cues instruct Drosophila sensory neurons to establish their unique dendritic fields on the body wall. In the latter part, I present two novel mechanisms, dendrite pruning and reshaping, that critically regulate dendrite plasticity in metamorphosis.. ...

Cancer-associated pain is a major cause of poor quality of life in cancer patients and is frequently resistant to conventional therapy. Recent studies indicate that some hematopoietic growth factors, namely granulocyte macrophage colony stimulating factor (GMCSF) and granulocyte colony stimulating factor (GCSF), are abundantly released in the tumor microenvironment and play a key role in regulating tumor-nerve interactions and tumor-associated pain by activating receptors on dorsal root ganglion (DRG) neurons. Moreover, these hematopoietic factors have been highly implicated in postsurgical pain, inflammatory pain and osteoarthritic pain. However, the molecular mechanisms via which G-/GMCSF bring about nociceptive sensitization and elicit pain are not known. In order to elucidate G-/GMCSF mediated transcriptional changes in the sensory neurons, we performed a comprehensive, genome-wide analysis of changes in the transcriptome of DRG neurons brought about by exposure to GMCSF or GCSF.

Pipids are highly aquatic frogs that rarely if ever venture out of water. They have several adaptations to aquatic life, including the loss of the tongue (tongues are not generally useful for feeding in water), and the presence of lateral line organs, which are used to detect wave motion in water (these are present in most groups of fishes). The group is sometimes called the Aglossa.. Pipid frogs are found in Africa, South America, and just get into Panama. Some species in South America, such as the Surinam Toad (Pipa pipa) are extremely flattened and look like roadkills. Females of the genus Pipa have an elaborate mating behavior, in which eggs are deposited on the back of the female, and the skin swells up around the eggs to encase them in pockets in which the embryos develop. In some species the eggs hatch out as tadpoles, but in others fully formed froglets emerge from the mothers back.. Tadpoles (when present) lack beaks and denticles, and have paired spiracles (if spiracles are present). ...

healthy.. The nervous system is the bodys inner communication system and is made up of the bodys many nerve cells.. It is these nerve cells that take information from the bodys five senses: touch, taste, smell, sound and sight! The brain is then able to react to these senses and interact with the environment.. The human nervous system is made up of the central nervous system (CNS) which is the brain and the spinal cord, and the peripheral nervous system which is made from nerve cells that carry information to and from the CNS.. When a sensory receptor detects a stimulus, the information is passed along neurones. Neurones are a special type of cell. They are found in groups/bundles of many hundreds of neurones known as nerves.. Looking in a little more detail we can see how the nervous system works: A stimulus is detected by a sensory receptor in the body. The receptor sends this information (via electrical impulses) along sensory neurones to the central nervous system (CNS). It is these ...

They are considered axons. Pseudounipolar cells have a bit of an odd morphology.. The reason you consider the entire length an axon is because it all grows from a single process from the soma which then branches. Terminology is just terminology, so rules are often made to be broken in biology: yes, an axon typically carries information away from the soma, but thats not the case here for neurons where the information sort of bypasses the soma.. Besides the developmental origin from a single process, the initiation site for an action potential is out in the distal end of the axon, rather than at an axon hillock connected to the soma, and if you had a section of axon on either side of the soma it wouldnt be apparent which end you were looking at.. ...

In the present study we showed increased TRPV1 activity after prestimulation of TRPA1, both in HEK cells and DRG neurons. This was dependent on calcium, AC, and PKA. Mutation of the putative phosphorylation site serine 116 in TRPV1 also abolished increased TRPV1 activity after TRPA1 stimulation. Together, our findings suggest that TRPA1 activation causes an influx of calcium and increases calcium-sensitive AC activity, cAMP accumulation, and subsequent PKA activation. This results in phosphorylation and sensitization of TRPV1.. Although some studies showed direct activation of TRPV1 by MO at high concentrations (Ohta et al., 2007; Everaerts et al., 2011; Gees et al., 2013), our control experiments and other studies showed that MO at a concentration of 20 µM did not directly activate TRPV1 (Fig. 2D; Jordt et al., 2004; Everaerts et al., 2011).. Approximately 30% to 50% of TRPV1-expressing small- to medium-sized peripheral sensory neurons coexpress TRPA1, and almost all TRPA1-positive neurons ...

We heard the fantastic news late last year that Matt was awarded an ERC Consolidator Grant! This is an amazing opportunity for us to push forward our work, and will allow us to do a whole heap of experiments that just wouldnt be possible with other types of funding. Well use it to focus on adult-generated neurons in the olfactory bulb, and how their elevated potential for plasticity might contribute to information processing in sensory circuits. In practical terms that means lots of slice physiology, as always, but well also now have the ability to monitor and control neuronal activity in vivo too, and thats incredibly exciting. Its a 5-year award starting later this year, so lets hope the UK Government sticks to its promise to underwrite all European funding obtained while were still part of the EU… If youd like to know more, you can find more detail on the award from the KCL IoPPN newsletter, and also in the ERCs own press release..
