Researchers discovered dopamine plays a crucial role in adapting decisions to changing situations. Using PET and fMRI scans, they found dopamine increases in the brain's reward center during task changes, aiding learning from mistakes.
New research reveals our internal biological clock significantly influences mood and well-being, with anxiety and depression peaking in the morning. This study, conducted in a controlled environment, offers insights into how circadian rhythms might affect mental health, independent of daily...
A study reveals that our brains better remember and connect information from people we like. Conducted by Lund University researchers, it shows how social preferences influence learning and memory integration, with implications for understanding social biases and polarization.
New research indicates crisis-related stimuli, like Hurricane Harvey and COVID-19, do not significantly disrupt cognitive attention in university students, unlike conventional emotional stimuli. This challenges assumptions about the salience of crises in affecting attentional processes.
Researchers showed that connectivity between different brain regions is more elaborate when letters are formed by hand. This improved brain connectivity, which is crucial to memory building and information encoding, may indicate that writing by hand supports learning.
Researchers discovered oligodendrocytes in the brain boost energy intake in response to neuronal activity, crucial for rapid signal transmission and brain health.
Tokyo University scientists found that oxytocin, a brain chemical, enhances memory in mice. By activating oxytocin-producing neurons, mice improved at recognizing objects over time. This discovery could help address memory disorders and provides insights into cognitive function.
New research explores the potential of AI to not just mimic human conversation but fundamentally supplant many aspects human cognition. The work, published in the journal Neuropsychology, raises concerns about the risks that AI chatbots might pose to higher order...
Researchers have demonstrated that lucid dreamers can control and respond to a virtual environment in their dreams, successfully navigating a virtual car. This study, published in the International Journal of Dream Research, marks a significant advancement in dream control technology.
Recent research examines why people are drawn to pseudo-profound statements, revealing that such susceptibility is linked to cognitive traits, such as a lack of critical thinking, and can influence behavior, societal beliefs, and even charitable giving.
A study found that ketone supplementation increased blood ketone levels in women but did not enhance cognitive performance during mental fatigue, despite subjective perceptions of improved performance. The research was recently published in the Journal of Cognitive Enhancement.
Researchers have discovered it's possible to communicate with people during various sleep stages, including REM, by receiving simple responses to questions and stimuli. This breakthrough enhances our understanding of dreams and opens new avenues for studying the sleeping brain.
Researchers have discovered "ACE points" where the brain's waste and immune signals directly exchange with its protective dura mater, challenging the belief in the brain's isolation and revealing a dynamic waste disposal and immune surveillance system.
Neuroscientists have found evidence that older adults' brains compensate for cognitive decline by increasing activity in the cuneal cortex, aiding in maintaining cognitive performance.
A study in Japan found people spend more time viewing paintings believed to be human-made vs. AI-generated, showing an implicit bias, despite no difference in their subjective evaluations of the art.
