Hyperexcitability in fear circuits is suggested to be important for development of pathological anxiety and trauma from adaptive mechanisms of fear. Hyperexcitability is proposed to be due to acquired sensitization in fear circuits that progressively becomes more severe over time causing changing symptoms in early and late pathology.

2022年8月3日 · Hyperexcitability in fear circuits is suggested to be important for development of pathological anxiety and trauma from adaptive mechanisms of fear. Hyperexcitability is proposed to be due to acquired sensitization in fear circuits that progressively becomes more severe over time causing changing symptoms in early and late pathology.

Fearful stimuli including fearful faces, fear inducing images, and fear conditioned cues, have been found to activate amygdala in several brain imaging studies using positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) [3–5].

2013年10月31日 · A fear-inducing situation activates a small group of neurons in the amygdala. Exposure therapy silences these fear neurons, causing them to be less active. As a result of this reduced activity, fear responses are alleviated. The research team sought to understand how exactly exposure therapy silences fear neurons.

2012年7月5日 · A simple test is to sense if an excitable thought in the mind (fear-based or joy-based) creates a sensation in your chest and gut area in an intense manner – it’s an indication of a strong momentum in the mind and an accumulation of suppressed emotional energy.

2024年5月10日 · We found that the CRF release in ovBNST during stress showed female-biased pattern, and ovBNST CRF neurons were more prone to be hyperexcited in female mice during stress in both in vitro and in vivo studies.

2024年9月30日 · We’ll explore the intricate dance of neurons and chemicals that orchestrate our fear responses, unravel the complex circuitry that processes threats, and discover how chronic fear can reshape our very brain structure.

2024年12月2日 · Discover effective strategies to manage and overcome phobias. Learn about education, relaxation techniques, exposure exercises, and cognitive strategies to reduce fear responses.

Fear is a normal and important emotion and response that helps us stay alive by being aware of threats. However, it can often lead to persistent anxiety and phobia which can be devastating for some. Seeking therapy and implementing coping strategies can help you live a …

2022年8月11日 · You can learn how to overcome fear and anxiety by learning more about the source of your fears, looking for the positive, and accepting your fears without judgment. You don’t have to let fear...
