The study found that Lactobacillus maintains interferon gamma levels , crucial for stress response and mental . well-being These insights offer a new avenue for developing treatments for mental health . conditions Key : Facts Lactobacillus , found in fermented foods , plays a crucial role in regulating the immune system and influencing mood . disorders The study successfully
High Good Cholesterol’ Linked to Dementia Risk Featured Neurology Neuroscience November 30, 2023 Summary : A new study found that abnormally high levels of HDL-C high-density lipoprotein cholesterol often referred to as good cholesterol’ , may increase the risk of dementia in older . adults This large-scale study , part of the ASPREE project , observed over 18,668 participants , noting that those with very high HDL-C levels had a 27 higher risk of dementia . The findings were particularly pronounced in individuals aged 75 and older , who showed a 42 increased . risk This research highlights the need for further investigation into the role of HDL-C in brain health and could aid in developing prediction algorithms for dementia . risk Key : Facts Very high levels of HDL-C 80 mg dL are
Cannabis and Alcohol Co-use Impacts Adolescent Brain and Behavior Featured Neuroscience Psychology November 30, 2023 Summary : Recent studies reveal effects of cannabis and alcohol co-use on adolescent rats , simulating human . behavior Rats voluntarily consumed THC-infused treats and alcohol , allowing researchers to observe changes in brain structure and behavior . Notably , co-use led to reduced synaptic plasticity in the prefrontal cortex , with effects more pronounced in female . rats The studies aim to understand cognitive disruptions caused by drug use in adolescence and develop treatment . approaches Key : Facts The study uniquely allowed rats to choose to consume both THC and alcohol , reflecting human drug-use . patterns Co-use of cannabis and alcohol in adolescent rats led to
Sleep Loss Impairs Decision-Making Featured Neuroscience November 30, 2023 Summary : A new study highlights the significant impact of sleep deprivation on decision-making processes . The research revealed that a single night without sleep dampens neural responses to decision outcomes , affecting both positive and negative emotional . reactions This study , which involved 56 healthy adults , found that sleep deprivation disrupts the brain’s response to risk-taking , potentially altering risk perception . These findings underscore the importance of adequate sleep , especially for professionals in high-stress roles like politicians and first responders , and suggest the need for specialized training or fatigue risk management in such . fields Key : Facts A single night of sleep deprivation
The researchers intend to continue obtaining data from the rest of the individuals in the ABCD dataset , comparing the performance of additional AI models . Credit : Neuroscience News AI Reveals Brain Differences in ADHD Featured Neuroscience Psychology November 30, 2023 Summary : Researchers utilizing artificial intelligence AI to analyze brain MRI scans have identified significant differences in white matter tracts of adolescents with . ADHD The study , involving over 1,700 participants from the multi-institutional Adolescent Brain Cognitive Development Study , used diffusion-weighted imaging DWI and a deep-learning AI model to detect these . variations Elevated fractional anisotropy FA values were found in nine white matter tracts in individuals with ADHD , providing objective
: Previous research has established that the brain region known as the hippocampus governs the formation and retrieval of episode memories . Credit : Neuroscience News Brain Activity in PTSD : Trauma Memories Differ from Sad Ones Featured Neuroscience Psychology November 30, 2023 Summary : A new study reveals distinct differences in brain activity between traumatic memories in PTSD patients and regular sad autobiographical . memories This research , the first of its kind to examine real-life personal memories , found that traumatic memories do not activate typical memory-related brain regions like the hippocampus , suggesting they’re not processed as regular . memories Instead , the study observed a unique neural representation of traumatic memories in the posterior cingulate cortex PCC
Tinnitus Linked to Auditory Nerve Loss Auditory Neuroscience Featured Neuroscience November 30, 2023 Summary : A new study reveals that tinnitus , a common auditory issue characterized by ringing in the ears , is associated with undetected auditory nerve loss . This finding challenges the traditional understanding that tinnitus is solely a result of brain maladaptation to hearing . loss The study shows that individuals with normal hearing tests but experiencing tinnitus actually suffer from cochlear synaptopathy , a type of hidden hearing loss . 8221 This discovery paves the way for potential treatments , including nerve regeneration through neurotrophins , bringing hope for millions affected . worldwide Key : Facts Tinnitus in individuals with normal hearing tests is linked to undetected
