          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.

          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.

          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.

          How the Brain Overcomes Instinctive Fear and Adapts to New Threats

          Researchers have identified brain mechanisms that help animals suppress instinctive fear responses when threats prove harmless over time. Using a visual threat model in mice, they found that specific areas of the visual cortex are necessary for learning to override fear, but not for storing the memory. Instead, the ventrolateral geniculate nucleus (vLGN) retains these learning-induced memories, regulating fear suppression.
