|
Information travels directly from the thalamus to the amygdala
|
|
|
The emotion results more slowly than it would via the “high road.”
|
|
|
It is an example of top-down processing
|
|
|
It is more likely to be utilized for complex feelings
|
|
|
It passes through the brain’s cortex

Detailed explanation-1: -Explanation: Joseph LeDoux described a “low road” of emotional processing, whereby sensations of arousing stimuli pass directly from the thalamus to the amygdala (as opposed to the slower, more deliberate “high road, ” in which stimuli are first processed by the cortex before being passed to the amygdala).
Detailed explanation-2: -Studies have shown that there are two pathways through which the amygdala’s fear responses can be triggered: a fast “low road” from the thalamus to the amygdala, and a slower “high road” that passes from the thalamus to the neocortex and only then to the amygdala, said LeDoux.
Detailed explanation-3: -Information about an external stimulus reaches the amygdala by two ways: by a direct pathway from the thalamus and by an indirect pathway from the thalamus via the cortex to the amygdala. The direct pathway is shorter and faster, but therefore provides only a crude representation of the stimulus.
Detailed explanation-4: -The amygdala is commonly thought to form the core of a neural system for processing fearful and threatening stimuli (4), including detection of threat and activation of appropriate fear-related behaviors in response to threatening or dangerous stimuli.
Detailed explanation-5: -The second central component is the proposal of a specific subcortical route of information processing-the so-called ‘low road’ (REF. 4)-that bypasses the presumably slower, resource-dependent cortex and that culminates in the amygdala by way of the superior colliculus and the pulvinar nucleus of the thalamus (FIG.
