Professor Karim Nader explains that fear learning, which is mediated by the amygdala, is different from other forms of learning.
Fear learning differs from other types of learning in a sense that how the system that mediates it is organized. So the system that mediates fear learning is called the amygdala and it receives sensory information about things that happen in the environment and things that are very emotionally salient. It is wired-up so that when it detects or learns that something in the environment is dangerous it engages a lot of these responses that are hard-wired in our brains and have evolved to save our lives. It is different in the sense of how the amygdala has been wired to mediate fear learning.

Professor Karim Nader explains that different brain regions are responsible for different types of memory. The hippocampus mediates conscious memory.
Professor Bruce McEwen discusses how the amygdala is involved in processing fear and stress.
The amygdala is a complex structure adjacent to the hippocampus. The amygdala is involved in processing emotions, and fear–learning.
Professor Karim Nader discusses a theory known as reconsolidation, which posits that when a memory is re-activated, it is subsequently re-stored.
The amygdala controls autonomic responses associated with fear, arousal, and emotional stimulation and has been linked to anxiety disorder and social phobias.
New research showing how memories take shape may lead to better treatments for unwanted memories as well.
Professor Karim Nader explains that the striatum is important to learning motor tasks, such as driving or bike-riding.
Professor Karim Nader explains that long-term memories are traditionally thought of as being fixed in the brain.
Professor Karim Nader discusses evidence that deep sleep can benefit learning motor skills such as riding a bike.
Doctor Daniel Pine explains that in rodents, humans, and other primates, the amygdala mediates the stress response. The prefrontal cortex (PFC) is also important.
