Thus, for example, mechanical, electrical and photic stimuli applied to the optic nerve produce no other sensation than that of light; and, conversely, any one variety of stimulus - take the electrical; for example - produces sensations of light, hearing, taste or smell, according as it ...
health, reducing risks of heart disease and even lowering the risk of death. Walking is one of the easiest ways to fit in physical activity, and even just a little more walking can make a difference. For example, taking an additional …Continue readingHow Many Steps a Day for Better ...
The cleavage of microRNA (miRNA) precursors by Drosha and Dicer and their loading with Argonaute proteins into RNA-induced silencing complexes are key steps in miRNA biogenesis. Recent studies have clarified the mechanisms of action of these molecular machines and discovered non-canonical miRNA biogene...
You’ve just watched JoVE’s video on how to evaluate the first six cranial nerves in a systematic way. We went over the essential steps of the examination, which can help uncover signs of the neurologic disorders associated with this set of nerves. The “cranial nerve exam part II” will...
How do the bones of the human skeleton move? Skeletal muscles contract and relax to mechanically move the body. Messages from the nervous system cause these muscle contractions. The whole process is called the mechanism of muscle contraction and it can be summarized in three steps: ...
Becoming a good object or a positive role model and even appropriate self-disclosure is acceptable and encouraged by the therapy alliance, just like displaying genuine sadness and empathy whilst hearing and ‘feeling’ a sad narrative; e.g., This is what it feels like to me, is this what ...
The consequences of such brain abnormalities include hypotonia, seizures, developmental delays, and hearing and vision loss, which all serve as the clinical manifestations of PDs [98]. Beyond PDs, peroxisomal dysfunction has been linked to some neurodegenerative diseases, such as AD, Parkinson’s ...
The sensitivity of hearing varies with the frequency of sound, being maximal around 2000–3000 Hz (the upper frequency range in speech) and falling off above and below this value (Fig. 131A). Clinical audiograms do not always make this point clear, however, since the threshold pressure is ...
machinery but also on several elements ensuring the proper sound-induced oscillation of the hair bundle or the ionic environment necessary to drive the MET current. Here, we review the most significant advances in the molecular bases of the MET process that emerged from the genetics of hearing. ...
K+ ions play a major role in many cellular processes. The deregulation of K+ signaling is associated with a variety of diseases including cancer. Ether-
