Is the hippocampus involved in fear conditioning?

Whereas the amygdala stores the memories of stimulus related to fear, the hippocampus seems to hold the contextual stimulus about fear. The functions of the structures indicate that the amygdala and hippocampus possess complementary roles in fear conditioning.

What does the hippocampus do with fear?

The hippocampus, responsible for many aspects of memory and spatial navigation, seems to play an important role in contextualizing fear, for example, by tying fearful memories to the place where they happened.

Is the hippocampus active during conditioning?

Hippocampal activity developed during acquisition of the fear response. The present data show learning-related amygdala and hippocampal activity during human Pavlovian fear conditioning and suggest that the amygdala is particularly important for forming new associations as relationships between stimuli change.

Does the hippocampus control memory?

Hippocampus is a complex brain structure embedded deep into temporal lobe. It has a major role in learning and memory. It is a plastic and vulnerable structure that gets damaged by a variety of stimuli. Studies have shown that it also gets affected in a variety of neurological and psychiatric disorders.

What is the role of the hippocampus in memory?

The hippocampus is thought to be principally involved in storing long-term memories and in making those memories resistant to forgetting, though this is a matter of debate. It is also thought to play an important role in spatial processing and navigation.

Is the hippocampus important in classical conditioning?

Trace conditioning, a form of classical conditioning in which the presentation of the conditioned stimulus (CS) and the unconditioned stimulus (US) is separated in time by an interstimulus interval, requires an intact hippocampus.

Is the hippocampus necessary for classical conditioning?

The hippocampus is widely believed to be essential for learning about the context in which conditioning occurs. This view is based primarily on evidence that lesions of the dorsal hippocampus disrupt freezing to contextual cues after fear conditioning.

What is the difference between hippocampus and hypothalamus?

The key difference between hippocampus and hypothalamus is that the hippocampus is a region located in the allocortex of the brain and controls motivation, emotions, learning, and memory, while the hypothalamus is a region located below the thalamus of the brain and controls body temperature, metabolic processes, and …
