Environment and Hippocampal Size Impact Depression in Youth
Summary: Challenging social environments and the size of the left hippocampus in children aged 9-11 contribute to an increased risk of depression. Researchers found that children with larger hippocampal volumes…
RNA Therapy Improves Memory and Reduces Anxiety
Summary: An RNA-based therapy, COG-201, can enhance memory and reduce anxiety in animal models by targeting the serotonin 5-HT2A receptor. Scientists found that decreasing this receptor’s expression led to improved…
Schizophrenia Linked to Disrupted Synaptic Plasticity
Summary: Researchers have identified a mechanism that impairs synaptic plasticity in individuals with schizophrenia, revealing the role of three key proteins. Using computational modeling, the team explored how genetic alterations…
Observing Trauma Boosts Resilience Through Serotonin
Summary: A new study reveals that observing others endure trauma can increase resilience and protect against depression. Researchers found that serotonin, released in the brain’s habenula, plays a key role…
How much does aging affect mental acuity? It’s debatable
