How do olfactory receptors work? How do auditory learners learn new information? How are visual, auditory and kinesthetic learners different? How does the vestibular system work? How does an ultrasonic transducer work? Why is there resonance of certain frequencies in the auditory canal?
How the sensory neurons in olfactory organs are stimulated? Describe the steps in the contraction of a muscle cell from the nerve impulse to the relaxation. What would the consequences be if your phrenic nerve was severed? How would antibodies against ACh receptors affect the neuromuscular junction...
We must also put melanism in context with feline communication. Felines rely heavily on smell for a good reason. Your kitty has 200 million olfactory receptors to your 5 million. That ability allows them to detect prey fromover 650 feet away. However, remember the typical cat’s activity pe...
Olfactory receptors (ORs) are chemosensors that are responsible for one's sense of smell. In addition to this specialized role in the nose, recent evidence suggests that ORs are also found in a variety of additional tissues including the kidney. As this list of renal ORs continues to expand,...
Light-activation of NpHR silenced the olfactory bulb and suppressed the aversion to TMT, while ChR2 activation induced the defensive response in the absence of TMT (Figure 3B). With this, the authors demonstrated that, by optogenetical affecting the neural circuit that transmits inform...
Several additional factors may contribute to malnutrition in the elderly, such as physiological, social, environmental, and health factors, including the loss/reduction of taste or olfactory function, delayed gastric emptying, and motility disorders [90]. Age-related changes in the gut microbiota may...
can bind to and activate it. Most of these receptors recognize multiple odors, and most odors can bind to multiple different receptors. What encodes the identity of a specific odor in the brain is determined by which combination of receptors are activated, and their relative strength of ...
et al. Enhancement of visual responses on the primary auditory cortex of the cat after an early destruction of cochlear receptors. Brain Res. 129, 162–164 (1977).References 62–67 are examples of the few animal studies that point to recruitment of the primary cortex of the deprived modality...
Even more impressive are the canine sense organs, especially the nose and ears. A dog's nose contains 225 million olfactory receptors, making it a very sensitive and nuanced sensory receptor [source: Frankel]. Humans, by comparison, boast a meager 5 million olfactory receptors [source: Correa]...
Murthy and colleagues studied this process in the olfactory bulb, which processes odors. "When a mouse encounters a scent, discrete loci in its olfactory bulb are activated, which in turn increases blood flow in those spots," Murthy says. "We measured all this using sophisticated optical microsc...
