AI Brain Model Reveals How Fear Works in Real Life

Researchers have developed an AI-driven brain model that can track fear as it unfolds in real-world situations, offering a major shift from traditional lab-based approaches. Classic fear studies often rely on static images, but these do not reflect how the brain processes fear in dynamic contexts.

Old Injuries Rewire the Brain to Feel Fear and Pain Forever

A new study reveals that even after healing, injuries can leave behind a hypersensitive nervous system that overreacts to future stress. Mice previously injured showed intense fear and renewed pain when exposed to a predator scent, despite no new harm.

Why Some Individuals Adapt to Fear Faster Than Others

A new study has uncovered the brain circuits responsible for individual differences in how animals adapt to repeated visual threats. Using advanced neural recording and manipulation tools, researchers identified two distinct pathways in the brain that drive either persistent escape or rapid habituation in mice.

Body’s Own Cannabinoids May Help Control Trauma-Linked Fear

A new study reveals that a natural cannabinoid in the body, 2-AG, plays a crucial role in regulating fear responses, particularly in individuals with PTSD and anxiety. Researchers found that lower levels of 2-AG in both mice and humans were linked to exaggerated or overgeneralized fear reactions to non-threatening stimuli. This suggests that 2-AG helps the brain distinguish real threats from harmless cues, acting as a natural filter for fear.

Brain’s Arousal Regulator Found

A new study reveals that a small cluster of cells near the brain's "blue spot"—the locus coeruleus—helps regulate arousal, attention, and stress responses. These peri-LC neurons modulate the locus coeruleus by releasing GABA, which reduces its activity and dampens the release of norepinephrine.

The Brain Learns to Fear Through Inference, Not Just Experience

A new study reveals how rats can learn to fear through inference, offering insights into the neural basis of higher-order emotions. By pairing a neutral sound and image, then associating the image with an unpleasant experience, researchers showed that rats later feared the sound alone—demonstrating inferred emotional learning.

Dopamine Signals Teach the Brain to Unlearn Fear

A new study reveals that dopamine release along a specific brain circuit helps extinguish fear by activating reward-related neurons in the amygdala. Researchers showed that dopamine from the ventral tegmental area (VTA) drives the brain’s positive learning process during fear extinction, rather than simply suppressing fear.

Psychedelics May Reset Brain-Immune Link Driving Fear and Anxiety

A new study reveals that chronic stress activates immune cells that travel to the brain, amplify inflammation, and heighten fear responses. Researchers found that psychedelics like MDMA and psilocybin disrupt this immune-brain crosstalk, reducing stress-related fear in mice and showing similar effects in human tissue samples.

Your Brain Learns From Fear, Thanks to Dopamine

New research reveals how dopamine helps the brain learn to avoid unpleasant outcomes by responding differently in distinct brain regions during negative experiences. In a study with mice, scientists tracked dopamine activity over time as animals learned to escape an adverse event, showing that one brain area adapted early in learning while another supported long-term avoidance behavior.

Children Show Fear Toward Peers Who Defy Gender Stereotypes

A new international study has revealed that children’s gender biases can be seen not only in what they say, but in how they express emotions on their faces. Researchers in Canada and Hong Kong studied over 600 children aged 4–9, analyzing facial expressions while they watched stories featuring gender-conforming and nonconforming peers.

Fear Sync: How Males and Females Respond to Stress Together

When mice face fear, they often freeze—and when paired, they typically freeze together. A new study reveals that male-female pairs maintain synchronized fear responses even under stress, unlike same-sex pairs.

Brain Circuit for Vicarious Fear Reveals How We Feel Others’ Pain

Scientists have uncovered a dedicated brain circuit that distinguishes between direct fear and fear learned by observing others—known as vicarious fear. The study shows that the right side of the brainstem’s locus coeruleus (LC) activates a specific pathway to the anterior cingulate cortex (ACC) during vicarious fear, while the left side processes direct fear.
