7) Our "stop" switch is located in:
a. Ventral tegmental area
b. Hypothalamus
c. Amygdala *not right, i chose that one
d. Prefrontal cortex

8)Nucleus Accumbens increases behaviors by:
a. recalling implicit memories
b. activating our prefrontal cortex
c. activating our survival circuitry *not right
d. a and c are correct

Expert Solution

7. d. Prefrontal cortex

Explanation
In engines stop switch is refered to a safety mechanism that used to shut off machinery in an emergency, when it cannot shut down in the usual manner.

Similar way in human body quick response is responsinlity of three precise parts of the brain that work together to stop body movements in an emergency scenario: the dorsal and ventral parts of the right ventrolateral prefrontal cortex, and the bilateral frontal eye fields.

Dorsal prefrontal cortex is especially interconnected with brain regions involved with attention, cognition and action,
Ventral prefrontal cortex interconnects with brain regions involved with emotion

8. a. Recalling implicit memories.

Explanation:

The nucleus accumbens present at preoptic area of hypothalamus, is primary site mediating reward behavior, and it is thought to be directly involved in reinforcing and addictive behaviors.Dopamine neuromodulators (along with other types of neurons) in ventral tegmental area (VTA) are activated during both rewarding and aversive moments.

Dopamine signaling may be involved with storing information about environmental stimuli associated with these positive and negative experiences. These memory stores can be called upon in the future. It helps to realize the pleasurable experiences again or avoid the aversive ones.

Implicit memory : is subdivision of the long term memory that is acquired and used unconsciously, and can affect thoughts and behaviours.

Problem 7-28 Make or buy Analysis {LO-7-3} “in my opinion, we ought to stop making our own drums and accept that outside accept supplier’s offer,” said Wim Niewindt, managing director of Antilles Refining, N.V, of Aruba. “At a price of $18 per drum, we would be paying $5 less, than it costs us to manufacture the drums in our own plant. Since we use 60,000 drums a year that would be an annual cost savings of $300,000. Antilles Refining’s current...
