A discrepancy between the actual and expected outcomes of a conditioning trial. Although, it is not known precisely that how the fear memory extinction pathway works in the learning and memory process, it is assumed that the hippocampus and amygdala are the main contributor in.

A further effect of fear motivation is to organize the perception of environmental events so as to facilitate the perception of danger and safety. The fear motivation system activates defensive behavior, such as freezing and flight from a frightening situation, and its function is to defend the animal against natural dangers, such as predation.

Brain mechanisms controlling pavlovian fear conditioning a key insight of associative learning theory is that learning depends on the actions of prediction error: Rodent studies have implicated a causative role for dopamine in the amygdala during fear.

Despite the breadth of risky situations in nature that demand diversity in fear behaviors, contemporary neurobiological models of fear stem largely from pavlovian fear conditioning studies that focus on how a particular cue becomes capable of eliciting learned fear responses, thus oversimplifying the brain's fear system. Fear is a defensive mechanism that rapidly activates coordinated bodily and behavioral responses to environmental stimuli that the brain, as a result of genetics and experience, has come to recognize as potentially dangerous.

When faced with a possible threat, the brain receives information from the sensory. It facilitates behavioral, hormonal, and autonomic “survival” actions to imminent threat via the hypothalamus and pag, while in the case of more distant or possibly escapable threat, it is likely to interact with prefrontal and striatal regions.

The amygdala is responsible for learning behavior, but it is also involved in regulating subjectively experienced feelings. Again, here is the brain involved:

However, It Is Also Important To Flexibly Readjust Fear Behavior When Circumstances Change.

Fear conditioning and extinction are basic forms of associative learning that have gained considerable clinical relevance in enhancing our understanding of anxiety disorders and facilitating their treatment. Recent evidence suggests that defensive responses to a predator and to fear conditioning associated with a painful stimulus use differentiable neural circuitry, rather than a common “fear system,” and that behavioral responses to a natural predator require participation of the hypothalamus. Notwithstanding the survival value, pain brings about emotional.

Amygdala and related corticolimbic regions are conventionally considered to be the key component of the threat processing system involved in the experience of fear and it is commonly hypothesized that they simultaneously control conscious awareness of fear in conjunction with automatic defense responses ( 96 ).
