Chapter 39.2, Problem 1CSC
Summary Introduction
To describe: The way in which the receptors that are associated with the electrical and chemical signals in animals allow them in perceiving their environments and also in generating behaviors.
Introduction: The nervous system is capable of storing great amount of information and it also exhibits different types of behaviors. The neurons carry out various specialized functions and they are connected in an orderly form. The signals from neurons regulate the muscle to exhibit various behaviors.

Students have asked these similar questions
The prefrontal cortex receives extensive input from the amygdala, and it uses information about emotion to make the final determination about whether to engage in a specific behavior. Bechara and his colleagues conducted a study on decision-making that compared healthy individuals to patients with damage to the prefrontal cortex. Which of the following statements about this research is FALSE?
A) Over time, patients with prefrontal injuries did not produce anticipatory reactions (sweating) before making a "risky" decision.
B) At first, both groups of individuals chose the "risky" option more often.
C) Both the healthy individuals and the patients eventually switched to the "safer" option once they figured out how the game worked.
D) Over time, healthy individuals began to produce a strong anticipatory reaction (sweating) before making a "risky" decision.
One finding that has emerged pertains to gender
differences in expression of emotions. Although both
genders are equally capable with expressing emotion,
research suggests that males are better at expressing
anger and females are better at expressing sadness and
fear. In general, females are better decoders than
males, even though no gender differences exist for
encoding.
Why do you think females learn to decode facial
displays of emotion better than males?
Briefly describe our brain's mesolimbic dopamine system.
(A) Which brain structures are involved in this system?
(B) What type of behavior does it regulate?
(C) Even though social media (or video games and the like) isn't something ingested, do you think this system is involved in our social media behavior? Or do you think something else is involved?
Please provide a brief, but specific response. Answer as much as you can please!!!!!!! Thank you!!!!!!

- Some researchers hypothesize that activity in certain regions of the brain represents the subjective value of an object being considered (meaning that the activity level in the brain region corresponds to how valuable the object is). (a) name a brain region that might represent the subjective value of an object being considered, such as a donut, and explain a research finding that supports your answer.
