Optogenetics To Regulate Sonogenetics
Sonogenetics is the use of sound waves to control neurons and other cells in the body, where as optogenetics is a light-based approach to manipulate neurons and other cells in the body. Optogenetics is when researchers add light-sensitive channel proteins to a neuron they wish to study. Salk Institute scientists shine a laser on the cell to activate or silence the target neuron. This approach can be difficult when studying cells deep in the brain; surgeons have to implant a fiber optic cable that can reach all the cells. Avoiding surgery, surgeons tried using sound waves to active calcium sensitive cells, similar to any cell in any organism, through microbubbles injected in the blood stream and distributed throughout the body of a nematode.

As the difference in these two waves is 10 Hz which is below 20 Hz, it is inaudible to the human ear. But there is a neuron called offer on neuron inside the ear which senses this 10 Hz and sends it to the brain as a stimulus.
Physics Of Ultrasound Essay
1344 Words | 6 PagesThe mechanical vibrations transmitted through a medium; solid, liquid or a gas generates a sound wave. The sound is an energy, which deflects the particles of a medium in the same direction, and itself travel as a longitudinal waveform with areas of compression and rarefactions. The image generated by ultrasound is essentially based on similar principle by means of a machine, which includes an ultrasound transducer and a screen. The transducer contains a piezoelectric crystal made up of lead zirconite, which generates an ultrasound beam on applying an electrical current to the transducer. These signals travel through a medium in the body and after striking with various tissues, return back to the transducer.

1834 Words | 8 PagesDepending on these differences, there may be an effect on the neural functionality. The first difference to consider is the Young’s modulus of the nerve and the electrode. The electrode, which is made from polysilicon, has a Young’s modulus of around 155 GPa1 while the nerve itself has a Young’s modulus of around 580 kPa2. A large mismatch in Young’s modulus can lead to the electrode being encapsulated by non-neuronal cells as the body attempts to minimize the damage caused by having something stiff inserted into soft tissue. The difference in Young’s modulus interferes with the
Future Of Sonography Essay
664 Words | 3 PagesWhat is The Future of Sonography? Sonography, also known as Medical ultrasound has constantly gained importance in the medical field since its invention over 30 years ago. Today, significant strides have been achieved in improving the efficiency and availability of ultrasound services so that radiologists can perform critical operations remotely preventing number of preventable deaths. The future looks promising with more advancement expected in terms of increasing the scope of procedures and also treatment capabilities.
Biotechnology: Designer Babies
903 Words | 4 PagesThe scientific term “designer baby” refers to a baby whose genetic makeup has been artificially selected by genetic engineering combined with in-vitro fertilization or IVF to ensure the presence or the absence of particular genes or characteristics. Doctors and scientist work together to conduct these procedures, and work to advance the technology and options for choosing an unborn child’s traits. Some even refer to “designer babies” as “test tube babies.” The reasoning behind these given names is because before the child is even born, the genes and DNA can be altered in a lab in a petri dish. When families choose IVF for “designer babies,” the doctors use biotechnology to choose what type of baby the family wants.

Extraordinary Relationships: Chapter Analysis
560 Words | 3 PagesGilberts (1992) states that “With these exercises, he obtained a measure of control over changes in attention, consciousness, thought and emotion” (pg. 127). With technology today biofeedback was created. It offers a way of training so that automatic responses can be modified. The three major areas of biofeedback training are reduction of striated muscle tension, training to increase temperature in the skin, and increasing the percentage of alpha rhythm in the EGG record, which measures electrical wave patterns of the brain (Gilberts, 1992, pg. 128).
Homogeneous Photothermolysis Case Study
1382 Words | 6 PagesDAC uses Nd YAG laser having homogeneous photothermolysis principle for removal of hair. Homogeneous photothermolysis is based on the fact that laser energy acts on a certain tissue volume homogeneously. Rapidly dividing cells with high cellular metabolism are the first to be affected by absorbed laser energy. The hair bulb cells in the anagen phase (period of active stable growth) have a high metabolic rate and are much more sensitive to heat. Surrounding tissue is preserved, while at the same time, hair follicles are irreversibly destroyed.
Essay On Electronic Baby Monitor
1131 Words | 5 PagesOne of the best buys of the trip, the electronic baby monitor is easy to carry in your handbag and the difference of models and prices is amazing. It is worth researching a little to carefully choose the best option for you. When you are expecting a baby, you want to make sure that the nursery is complete. You have the crib, the changing table, the dresser and the mobile phone, but you have a baby monitor?
Inoperable Tumours
322 Words | 2 PagesI challenge myself every year by completing a science fair project for the Canada Wide Science Fair outside of school requirements in addition to many other extracurricular activities I pursue, such as balancing academic marks above 90%, participating in school volleyball and community girls’ and co-ed fastball and girls’ hockey teams, preparing for the Royal Conservatory of Music grade nine piano examinations, participating in music festivals and competitions and helping on the family farm year-round. My most recent national-calibre science fair project, "Extracorporeal Sonic Wave Therapy for Inoperable Tumours" presented me with many challenging obstacles. Originally, the idea was to use infrasonic sound waves to target specific cells;
Essay On Mechanistic And Teleological Explanations
743 Words | 3 PagesI argue that while mechanistic and teleological explanations are distinctly different, both are required in order to thoroughly explain a phenomenon. In this essay, I will describe mechanistic, atomistic, and teleological explanations, highlight their key differences, and then explain why one cannot completely understand a phenomenon without incorporating a teleological component. A mechanistic explanation is one that describes “how” a phenomenon (such as breathing, growing, or eating) occurs. It conveys the physiological, or physical, movements and changes involved in that phenomenon.
Interpreting The EEG Essay
1478 Words | 6 PagesThe electrodes are attached to the scalp, and when the neurons in your brain communicate via electrical impulses, this activity then can be portrayed as wavy lines on an EEG recording. Since brain cells are always in constant activity, the EEG really measures the change in electrical impulses or response. Traditionally, an EEG is used as a main diagnostic test for epilepsy and other brain disorders15, but in recent years, EEG technology has begun to stretch far beyond the bounds of medical. For example the EEG is beginning to be used in clinical studies, even though some individuals remain sceptical about the EEG’s value as a research tool. For example, Ashcroft, the author of The Spark of Life: Electricity in the Human Body, compares interpreting the readings from the EEG to trying to understand the relationships between people living in a city like New York, simply by listening in on all of their telephone calls at once, making it impossible to pick out individual conversations.

Fear Of Crime Essay
1485 Words | 6 PagesIn 1990’s The study found that, even though crime rates fell over the period of the study (according to the FBI) people’s fears about crime fell and rose during that period, along with TV violence rates. Incidents of TV violence on broadcast television have increased since the late 1990s — as has the public’s fear of crime, the study said. The findings suggest that TV drama may “transport” viewers emotionally into the imagined world of TV shows in a way that creates fear of crime beyond the influence of the national violent crime rate or the reported perception of local crime (www.deadline.com/2016) Dan Romer and director of the Annenberg Public Policy Center, said “We now have stronger evidence that the fictional treatment of crime on
