<h3>What are Neurotransmitters?
</h3>
Neurotransmitters, which are organic compounds, play a major role in the language that neurons use to communicate with one another and with their final targets. Following electrical stimulation, these substances are produced and act on their particular receptors to start a response that can be as simple as a muscle contraction or as extremely complex as starting a chain reaction that eventually changes how the organism behaves. Neurotransmitters can have multiple functions; depending on where they act, they can be neuromodulators or, in some cases, neurohormones.

Answer: Schemas
Explanation:
Rachel's situation fits in the memory concept of schemas. A schema can be defined as the framework that helps a person organize and interpret information.
Schemas can be very useful when a person needs to remember something, they are like that support or staff to continue with the process of interpretation to which people are subject through their experiences in the daily life.
While schemas can be positive they also have aspects that would not be so flattering. When a person relies on its schemas, it may be taking into account the interpretation it makes of each one, it is based on its ideas and the perceptions it has about the world and often does not look more objectively. Several psychologists have used the term schema in their work on learning. Piaget in his theory of cognitive development expresses that people adapt as they acquire information and change their schemes. That is to say, a person when it has an interpretation of something and then acquires more knowledge is prone to the schema-changing since its perception of the fact can change by having acquired more information.
The schemas that a person has many times do not change even having more information. It is easier for a child to change their schemas than for an adult. The adult, even knowing something, may not change because they may feel they are trying to change their thinking.
Schemas can be very positive and contribute to a better learning process, but the person must also have a more open attitude to assimilate opinions and information that often will not go along the same lines of their thoughts and ideas.
