Detailed explanation-1: -The researchers used a rigorously controlled experiment with a placebo condition to avoid the effect of confounding (extraneous) variables. The study is able to establish a cause-and-effect relationship; however, it is a reductionist approach to understanding memory.
Detailed explanation-2: -Glutamate: The most plentiful neurotransmitter found in the nervous system, glutamate plays a role in cognitive functions such as memory and learning.
Detailed explanation-3: -Rogers and Kesner (2003) found that scopolamine injected directly into CA3 impaired maze acquisition by means of impaired encoding, whereas injections of physostigmine directly into CA3 impaired acquisition by means of impaired consolidation.
Detailed explanation-4: -Acetylcholine (ACh) plays an important role in memory function and has been implicated in aging-related dementia, in which the impairment of hippocampus-dependent learning strongly manifests. Cholinergic neurons densely innervate the hippocampus, mediating the formation of episodic as well as semantic memory.
