With regard to motor cortex, a population vector is the Select one: a. summed activity of the neurons in the motor cortex, including cells that are tuned to all directions. b. summed activity of the neurons in the motor cortex, including only cells that are tuned to the same preferred direction. c. activity of many neurons with different preferred directions averaged together, resulting in the final movement vector d. preferred direction of a single neuron.

Option "B" is the correct answer to the following question.

Explanation:

A population vectors in the visual cortex is the combined activity of neurons in the motor cortex, comprising cells oriented to  Particular all direction.

each of the 46 original chromosomes splits into two daughter chromosomes, so there are two sets of 46 daughter chromosomes that end up in each cell. human cells have 46 chromosomes. each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere.

hydroxyl -oh

alcohols, always polar, can form hydrogen bonds with h2o molecules

carboxyl -cooh  

cargoxylic acids, has acidic properties which is a source of hydrogen ions, found in cells in ionized for with a charge of oh-1

carbonyl > co

ketone if within skeleton, aldehyde if group is at the end of skeleton, k & a may be structural isomers, it determines 2 sugars (ketose & aldose)

amino -nh2

amines, acts as a base, it can pick up h+ ions from surrounding solution, ionized with charge of 1+

methyl ch2

addition to rna/dna affects and gene expression

phosphate -opo3 ²⁻

organic phosphates, contributes to negative charge to, molecule that it is a part of, and potential to react with h20

sulfhydryl -sh

thiols, cross-linking stabilize the protein, and it is structure
