New research shows that astrocytes, not neurons, are key to stabilizing emotional memories by being biologically tagged with adrenoreceptors after intense experiences, and re-engaging during recall. Manipulating these astrocytes affects memory stability and fear responses, opening potential therapeutic avenues for PTSD and trauma-related conditions.
A study describes a 17-year-old girl with hyperthymesia who has an extraordinary, organized internal memory system that allows her to vividly relive past events with emotional depth, structured in a mental 'white room' with dedicated spaces for different memories and emotional states.
A study reveals how the amygdala and hippocampus coordinate to encode and retrieve emotional memories, with specific gamma activity patterns in the amygdala shaping hippocampal responses that are later reactivated during recall, providing insights into emotional memory vividness and potential treatments for PTSD.
Researchers have identified a mechanism in the prefrontal cortex involving corticotropin-releasing factor (CRF) neurons that modulate empathetic responses based on past emotional experiences. This discovery, highlighting how animals respond to others' emotions when they mirror their own past experiences, offers insights into empathy's evolutionary conservation and potential therapeutic targets for conditions like PTSD, autism, and schizophrenia.
A study published in Frontiers in Behavioral Neuroscience suggests that the shift towards a more positive attitude, commonly observed in older adults, may begin as early as late middle age (48-59 years old). The research found that late middle-aged individuals displayed a greater preference for positive and neutral scenes compared to early middle-aged adults, indicating a potential early emergence of a positivity bias. These findings could inspire further studies on emotional processing at different life stages and provide insight into how aging impacts cognitive and emotional well-being.
