Sweat, heartbeats, muscles tense. Your stomach is turning. We can feel pleasure when fear is gone. Is this just the relief of being alive?

The fear response is controlled by the almond-shaped bundle of neurons in the amygdala. The fight-or-flight response occurs when the amygdala stimulates the sympathetic nervous system and the adrenal cortical system.

The body gets a boost from Adrenaline. Blood is diverted from the core to the muscles needed for movement. Blood pressure is raised byCortisol. The vital organs are flooded with blood vessels. Breathing quickens, delivering fresh oxygen to the brain, while levels ofglucose in the blood spike, giving the body a quick energy boost

According to Dr Charlotte Lawrenson, a neuroscientist at Bristol University, there are still many unknowns regarding neural fear networks.

In early societies, fear-inducing tales were used to teach children about dangers they might encounter

Two pathways are activated in the brain when we are exposed to sensory stimuli. The first is moving quickly. Immediate action on threatening stimuli can be taken with the transfer of information to the thalamus and amygdala.

It is an indirect route. Information is sent from the thalamus to the cortex. We can determine if we are in real danger by analyzing the threat.

"We don't know where the feeling of fear occurs in the brain, but it's likely to be from the coordinated activation of a fear network involving multiple brain regions."

Other parts of the brain will be activated if the threat is real. The periaqueductal grey is involved in the antinociceptive, autonomic and behavioural reactions to stress and injury.

The danger will be stored in the hippocampus in order to be remembered at the next encounter.

Human history has a history of fear. Children were taught to fear wolves and other predatory animals in early societies. Cinema gives a glimpse into society's fears. The shared anxiety about the second world war was revealed in the sci-fi film.

In 2001: A Space Odyssey and Skynet, there are machines that revolt against their creator, similar to the Westworld hosts. The emergence of a serial killer in the public consciousness in the late 1970s and 1980s led to the appearance of Michael and Freddy.

When the pandemic went into hyperdrive, downloads of the movie Contagion increased. Why did people want to see a film about a real thing? horror films have the potential to learn about uncertainty management.

The cognitive processes involved in play and learning are researched by an associate professor at a university. He says that spending time in these fictional realm can be thought of as an opportunity to draft up your own instruction book.

People who liked watching scary films were more resilient than people who didn't.

They have been exposed to similar scenarios and may use that to navigate new realities. It's possible that recreational forms of fear can help regulate emotions.

It makes sense if you see fear as a form of play. Getting a grip on unpredictable situations is related to enjoying scary stimuli. Children's play is characterized by seeking out moderate amounts of uncertainty and moderate surprises to make sense of them.

Children's play that involves risk and fear can function as a protective factor against anxiety. The strategy of play is to learn how to deal with unpredictable situations.

They studied a group of people who went to a haunted house and found that they enjoyed it. The guests agreed to be terrified by zombies, maniacs and child-eating murderers. The guests were filmed, monitored, and asked how they felt during the experience.

A large special-effects department and about 70-100 scare actors each night, that's how many scare actors there are at Dystonia haunted house. They challenge their guests on a lot of different levels, including disgust, fear, jump scare, unease, being alone, and claustrophobia.

There might be a sweet spot between fear and enjoyment. The context is not too frightening but not too tame. The sweet spot seems to be where you can enjoy the most.

The release of feel good chemicals in the brain after a flood of fear is rewarding you with a rush of euphoria.

Everyone is different and it's important to remember that. There is a fine line between harmless fun and genuine terror, and we all have a sense of what scares us. Fear can lead to problems. A quarter of a billion people suffer from anxiety disorders, which can affect a person's life path.

Different people have different levels of brain activity.

It can be frightening for someone to be a thrill for one person. This Halloween is a good time to be scared.
