Answer:

Michael Gazzaniga and Roger W. Sperry.

Sperry severed the corpus callosum in cats and monkeys to study the function of each side of the brain. He found that if hemispheres were not connected, they functioned independently of one another, which he called a split-brain. The split-brain enabled animals to memorize double the information.

Answer:

Michael Gazzaniga and Roger W. Sperry

Explanation:

Split-brain also known as callosal syndrome was considered successful after it had passed three types of tests to analyze the range of cognitive capabilities of the split-brain subjects. The first was the visual stimulation ability test, the second test was a tactile stimulation situation and the third tested the auditory abilities of the patient.

The reactivity of an atom is directly determined by
sertanlavr [38]

Answer: B) The number of electron in its valence shell.

Explanation:

Outermost electrons of the atoms which can participate in the chemical bond formation is known as valence electrons.  

Atoms either transfer or share its valence electrons during chemical bond formation. Atoms transfer or share electrons to attain octet or in other words stability.

Generally, 8 electrons are required in their outermost shell or valence shell in order to attain stability. This rule is known as octet rule.

For example, general electronic configuration of sodium belonging to group 1 is  1s2 2s2 2p6 3s1.

No. of valence electrons in Na = 1

by loosing 1 electron, its outer shell electronic configuration become =  1s2 2s2 2p6 (Octet)

Hence, sodium and other group 1 elements are very reactive.

Similarly, halogens (ns2 np5) by gaining 1 electron attain octet (ns2 np6). Hence halogens are also very reactive.

Carbon atom belonging to group 14 has 4 valence electrons (ns2 np2) and share all 4 valence electrons to attain octet and hence reactive.

Nobel gases have octet in their outermost shell (ns2 np6), hence they are most nonreactive element.
