How could you use different research methods to complement each other when studying a particular process in the brain?

Answer is given below

Explanation:

  • The brain is a complex structure and requires different methods to be declared in order to obtain a clear illustrator.  Cavalder study is a method of comparing the brain of a dead person. For example, Einstein compared the brain to the brain of ordinary people.
  • It has been hypothesized that the proportion of glia cells in the neuron is higher in a person with a higher IQ, such as Einstein. However, it cannot be confirmed that only a specific brain is available.  The study of the session helps us to identify the problem associated with defects in a particular area and eliminates the function of a specific area of ​​the brain. For example, clots form in the frontal lobe during a stroke, which can sometimes lead to epilepsy.
  • The disadvantage of these methods is that the brain is not active. A new method of EEG electroencephalogram that measures electrical signals if each neuron is present. It measures brain activity when the brain is active. The EEG can provide information about the normal patterns of electrical activity in the brain, and although the EEG allows the researcher to quickly observe when these changes occur in real time, the electrode measures the surface of the skull and each electrode measures brain waves from large areas to be placed on the brain.
  • EEGs do not provide a very clear picture of brain structure. The image of the brain cannot be obtained by changing the electrode to measure the electrical signal.  but there are MRI techniques to provide more specific brain images. Functional magnetic resonance imaging uses the scan method using magnetic fields to create an image of the brain in each activity field.  Therefore all mixed methods can help to study the brain and related activities more deeply and effectively.

meriva

Answer:

The correct answer is option D: "Strategic".

Explanation:

Strategic planning refers to a series of steps that an organization needs to follow in order to achieve the goals of the institution, in this case, a hospital or the orthopedic unit. Strategic planning is usually performed by the directors of the institution, therefore, this type of planning will be the least useful during the first shift to treat the 75-year-old client. Other types of planning focused directly on the client are more useful than strategic planning at this point of the treatment.

Sound quality can be divided
iris [78.8K]
Sound quality can be divided into amplitude, timbre and pitch. If there’s an impedance mismatch between your two devices connected to the single output, you could have a large mismatch between the levels arriving at each device. If the difference is large enough, one device may have distorted or inaudible audio.

To avoid this, you should ensure that both devices connected to the split signal are similar - such as 2 pairs of headphones, 2 recorder inputs, and so on. When you place 2 devices with wildly differing load impedances on a splitter is when you’ll encounter problems - such as headphones on one split and a guitar amp input on the other.

To get around this, you can use either a distribution amplifier (D.A.) or a transformer balanced/isolated splitter - which will work over a larger range of load impedances, typically. Depends on the quality of the splitter and the exact signal path. If you’re using the splitter to hook two things into one input, and you’re using quality connectors, you probably won’t lose much quality. There can be an increase in impedance of the cable due to the imperfect continuity of the physical connection, however with unbalanced line-level signals, impedance at both ends of the chain tends to be orders of magnitude higher than the connection will create, so one split will be barely noticeable. So too, the noise increase from the additional length of cable.

Now, one source into two inputs, that will by basic math and physics result in a 3dB drop in signal strength, which will reduce SNR by about that much. By splitting the signal path between two inputs of equal impedance, half of the wattage is being consumed by one input and half by the other (the equation changes if the inputs have significantly different impedances). So each input gets half the wattage produced by the source to drive the signal on the input cable, and in decibel terms a halving of power is a 3dB reduction. Significant, until you just turn the gain back up. The “noise floor” will be raised by however much noise is inherent in the signal path between the split and the output of the gain stage; for pro audio this is usually infinitesimal, but consumer audio can have some really noisy electronics, both for lower cost and because you’re not expected to be “re-amping” signals several times between the source and output.
