Scenario II
The following model of emotion is based on the following work:
LeDoux,J.E.(2000) .Emotion circuits in the brain.Annual Review of Neuroscience,23,155-184.
The psychologist Joseph LeDoux tracked the neural mechanisms underlying the fear response in rats.Rats were exposed to the sound of a tone followed by an electric shock.After a few tone-shock pairings,the tone elicited species-typical defense behaviors such as freezing and increased sympathetic activity (e.g. ,an increase in heart rate) .Using this fear-conditioning paradigm,LeDoux argued for the existence of both fast and slow neural pathways underlying the fear response.A particular brain structure (arbitrary labeled "A") simultaneously routes sensory information to structures B and C.In the fast pathway,information is routed to structure C-a limbic structure long known to be involved in emotional experiences such as fear-where it is rapidly assessed.If appraised as a threat,structure C activates the fear response.In the slow pathway,information travels to other structures in the brain (labeled "B") involved in planning and more advanced decision making.The results of the appraisal by structure B is used by structure C to continue or terminate the fear response.
-(Scenario II) Brain structure C corresponds to the:

Definitions:

Sensory Neurons

Nerve cells that are responsible for converting external stimuli from the organism's environment into internal electrical impulses.

Interneurons

Neurons that are located in the central nervous system and transmit signals between sensory neurons and motor neurons.

Glial Cells

Glial cells are non-neuronal cells in the central and peripheral nervous systems that support and protect neurons.

Motor Neurons

Neurons that are components of the route through which signals travel from the brain or spinal cord to muscles or glands.
