Analyzing data from over 1,000 patients globally, they found that 94% of PCA cases predict Alzheimer's, with the rest linked to conditions like Lewy body disease. ]]> https://neurosciencenews.com/early-alzheimers-vision-25510/feed/ 0 https://neurosciencenews.com/pupil-depression-25458/ https://neurosciencenews.com/pupil-depression-25458/#respond Mon, 15 Jan 2024 22:17:40 +0000 https://neurosciencenews.com/?p=99415 Researchers found a distinct correlation between pupillary response and depression severity. Researchers observed that in healthy individuals, pupils dilated in anticipation of a reward during a task, while this response was notably subdued in those with depression, especially in patients experiencing listlessness. ]]> https://neurosciencenews.com/pupil-depression-25458/feed/ 0 https://neurosciencenews.com/retina-color-vision-25447/ https://neurosciencenews.com/retina-color-vision-25447/#respond Thu, 11 Jan 2024 18:06:56 +0000 https://neurosciencenews.com/?p=99370 In a groundbreaking study using lab-grown human retinas, researchers unveil the process behind our ability to see millions of colors, a trait unique to humans. The findings challenge previous beliefs and demonstrate how retinoic acid plays a crucial role in determining whether specialized cone cells sense red or green light. ]]> https://neurosciencenews.com/retina-color-vision-25447/feed/ 0 https://neurosciencenews.com/sensory-eating-25401/ https://neurosciencenews.com/sensory-eating-25401/#comments Thu, 28 Dec 2023 22:22:58 +0000 https://neurosciencenews.com/?p=99155 The science of eating behavior goes beyond hunger cues; it involves sensory stimuli, internal signals, and the gut-brain connection. External cues like food packaging and advertisements influence our eating decisions, but internal signals, such as hunger and fullness, play a profound role. ]]> https://neurosciencenews.com/sensory-eating-25401/feed/ 1 https://neurosciencenews.com/visual-motor-learning-25395/ https://neurosciencenews.com/visual-motor-learning-25395/#respond Sun, 24 Dec 2023 19:59:58 +0000 https://neurosciencenews.com/?p=99123 Researchers found that visual aids creating illusions of movement, like screens showing a hand's motion, can enhance motor performance and early-stage motor learning. Functional near-infrared spectroscopy revealed distinct brain activity changes in motor learning regions compared to traditional third-person motion observation. ]]> https://neurosciencenews.com/visual-motor-learning-25395/feed/ 0 https://neurosciencenews.com/daydreaming-visual-neuroscience-25359/ https://neurosciencenews.com/daydreaming-visual-neuroscience-25359/#comments Thu, 14 Dec 2023 19:33:01 +0000 https://neurosciencenews.com/?p=98974 Researchers made a breakthrough in understanding how daydreaming affects the brain.
