Which brain imaging techniques allow for the observation of structure but do not allow observation of brain activity?

1 answer:

6 0

With the use of cutting-edge noninvasive neuroimaging methods like EEG and fMRI, researchers may now watch brain activity while volunteers carry out different perceptual, motor, and/or cognitive tasks.

<h3>Which three methods enable the study of the active brain?</h3>

There are several ways to go about gathering data about the anatomy and activities of the brain. Functional magnetic resonance imaging (fMRI), magnetoencephalography (MEG), and electroencephalography are the three most popular and often utilised measurements (EEG)

<h3>Why is fMRI employed?</h3>

It can be used to investigate the functional architecture of the brain, identify the regions of the brain responsible for vital functions, assess the consequences of a stroke or other illness, or determine how best to treat the brain. Other imaging methods may be unable to find abnormalities in the brain that fMRI can.

Papessa [141]

The initial population was 80

<h3>Solution ;</h3>

The bacteria culture has a constant growth rate.

So, N(t) = No*(1 + r)^t

Solution :

400 = No*(1 + r)^2

50000 = No*(1 + r)^8

(1 + r)^6 = 125

=> 1 + r = 2.2360

No = 400÷(1 + r)^2 = 80

Hence, now we can conclude that the initial number of the bacterial culture was 80.

The point at which the trachea (windpipe) divides into right and left primary bronchi may be determined by locating the sternal

MrRa [10]

True.

<span>The trachea is about 10 cm long and it has an approximate diameter of 2 cm. It is located anterior to </span>(in front of) the esophagus and posterior to (behind) the isthmus of the thyroid. The right and left main bronchi are branches of the trachea. This division occurs at the level, or just below the level, of the sternal angle, also known as the manubriosternal joint.
