Neuroscience News Home

Neuroscience News is an independent open access science magazine. Since 2001, we have featured neuroscience research news from labs, universities, hospitals and news departments around the world. Topics include brain research, AI, psychology, neuroscience, mental health and neurotech.

Science news articles cover neuroscience, neurology, psychology, AI, mental health, robotics, neurotechnology and cognitive sciences.

Researchers discovered new variations of the visual saltation illusion, where rapid light flashes in peripheral vision create perceptual errors. Their study shows that our brains misplace the second flash near the midpoint, regardless of its actual position.
A new study explores the impact of the internet on human morality, highlighting how evolved responses like compassion and the urge to punish are distorted online. The internet's constant stream of extreme stimuli leads to compassion fatigue, public shaming, and virtue signaling.
Researchers created a virtual rat with an AI brain to study how real rats control movement. Using data from real rats, they trained the AI to mimic behaviors in a physics simulator. The virtual rat's neural activations closely matched those of real rats, offering new insights into brain function. This innovation could revolutionize neuroscience and improve robotic control systems.

Neurology news articles cover neurology, brain cancer, traumatic brain injuries, neurosurgery, neuroanatomy, brain research and neurological disorders.

Eli Lilly’s Alzheimer’s drug, Donanemab, has been recommended for FDA approval by an independent panel. The drug has shown promise in slowing early-stage Alzheimer’s, despite risks like brain swelling. This recommendation follows a prior FDA rejection due to insufficient data. If approved, Donanemab could revolutionize Alzheimer's treatment, offering new hope for patients and their families.
The protein Kif2a acts as a "gardener" for sensory neurons, regulating their axon growth. This pruning process is crucial for managing pain sensitivity. The absence of Kif2a in genetically engineered mice resulted in increased axon density and heightened pain sensitivity over time. However, a compensatory mechanism reduces pain sensitivity in the long term, offering potential insights for chronic pain management.
Poor olfaction in older adults may predict the development of heart failure. The study followed 2,537 participants and found that those with a reduced sense of smell had a 30% higher risk of developing congestive heart failure. This finding suggests a need to further explore the relationship between sensory deficits and heart health. Understanding this link could lead to better early interventions for at-risk populations.

AI news articles cover science articles about artificial intelligence including ChatGPT, Bard, Dalle, neural networks, machine learning, LLMs, AGI and other AI related topics.

Wild African elephants use name-like calls to address each other, a rare ability among nonhuman animals. Researchers confirmed this by using machine learning to analyze elephant calls and observing that elephants responded specifically to calls addressed to them.
Popular AI platforms like ChatGPT give inconsistent answers to reasoning tests and don’t improve with added context. The research highlights the need to understand AI 'thinking' before using them for decision-making. Despite advances, AI models often make simple errors and fabricate information.

Science research articles cover psychology, depression, mental health, schizophrenia, mental disorders, happiness, stress, PTSD, autism, psychiatry and therapy.

Depressive symptoms and memory decline in older adults are closely linked, each influencing the other. Using 16 years of data from 8,268 adults, researchers found that depression can precede memory decline, and poor memory can lead to increased depressive symptoms.

Researchers found that a hormone-producing cell in the adrenal glands may explain why oldfield mice are monogamous while their close relatives are promiscuous. This hormone, 20⍺-OHP, boosts nurturing behavior, suggesting a link to monogamy.
Fruit flies use the neurotransmitter octopamine to decide whether food memories are stored long-term or short-term. This process, influenced by energy reserves, affects future eating behavior. High glycogen levels result in stable food memories, prompting increased food intake even after fasting. The research suggests that similar mechanisms may influence overeating in humans.
A new study finds that altered states of consciousness (ASCs), like those experienced during meditation, are more common than previously thought. 45% of respondents reported experiencing ASCs at least once, often leading to positive outcomes. However, a significant minority also reported negative or even life-threatening suffering, highlighting the need for better support and understanding of these experiences.
