Multiple topographic maps is a feature that is advantageous because it allows maps of different sizes that would accommodate varying levels of acuity and details in signals. A more detailed map has more neurons that would take up more area than a more global map, which would require fewer connections. [13]
The idea is to use a biometric system to measure the eye using only a small number of points across the retina with random flashes of photons that "read" the retina and identify the individual. [56] This biometric system would only allow a certain individual with a specific retinal map to decode the message.
The most detailed reconstructions have been performed on the basis of the mitochondrial genomes shared by all eukaryotic organisms, [3] which are short and easy to sequence; the broadest reconstructions have been performed either using the sequences of a few very ancient proteins or by using ribosomal RNA sequence.

[3] [8] This raw pattern of neural activity is called the proximal stimulus. [3] These neural signals are then transmitted to the brain and processed. [3] The resulting mental re-creation of the distal stimulus is the percept. To explain the process of perception, an example could be an ordinary shoe. The shoe itself is the distal stimulus.
A coronary artery bypass graft can be performed, whereby a blood vessel from another part of the body (the saphenous vein, radial artery, or internal mammary artery) is used to redirect blood from a point before the narrowing (typically the aorta) to a point beyond the obstruction.
[2] [3] [4] Crash Course was one of the hundred initial channels funded by YouTube's $100 million original channel initiative . The channel launched a preview on December 2, 2011, and as of March 2022 [update] , it has accumulated over 16 million subscribers and 1.8 billion video views. [ 5 ]
Just as maps are normally oriented with north at the top, the standard body "map", or anatomical position, is that of the body standing upright, with the feet at shoulder width and parallel, toes forward. The upper limbs are held out to each side, and the palms of the hands face forward. [1] Using the standard anatomical position reduces confusion.
In cognitive science and neuropsychology, executive functions (collectively referred to as executive function and cognitive control) are a set of cognitive processes that support goal-directed behavior, by regulating thoughts and actions through cognitive control, selecting and successfully monitoring actions that facilitate the attainment of chosen objectives.
