28 kwi 2016 · In this review, we summarize the current knowledge on the brain circuits processing innate fear responses to a wide variety of threats, including predators, aggressive conspecifics and painful stimuli. Accumulating evidence indicates that innate fear to these different types of threats relies on parallel nonoverlapping circuits.
Examples of innate fear include fears that are triggered by predators, pain, heights, rapidly approaching objects, and ancestral threats such as snakes and spiders. Animals and humans detect and respond more rapidly to threatening stimuli than to nonthreatening stimuli in the natural world.
10 paź 2019 · Fear can be innate or learned. Innate fear can be expressed in response to environmental stimuli without prior experience, such as that of snakes and spiders in humans and to predator odor in...
14 paź 2024 · Exposure to predators has been used effectively to study innate and conditioned fear responses in rodents, including exposure of rats to cats, and mice to rats.
19 sty 2017 · Fear, a noble and sophisticated brain function, requires a perfect integration of emotional and cognitive inputs. A new study investigate where innate fear come from.
1 sie 2012 · An important distinction is made between 'innate fear' responses that are activated by intrinsically threatening stimuli and 'learned fear' that is elicited by neutral stimuli that have...
15 wrz 2016 · We propose that these circuits are contained within three main functional units in the brain: a detection unit, responsible for gathering sensory information signaling the presence of a threat; an integration unit, responsible for incorporating the various sensory information and recruiting downstream effectors; and an output unit, in charge of ...
