"Unveiling the Brain's Alertness Mechanism: From Daydreams to Reality"

Originally Published 1 year ago — by Neuroscience News

Researchers at Boston Children’s Hospital have uncovered the brain mechanism responsible for transitioning from daydreaming to alertness and memory formation, centered around activity in the dentate gyrus. This mechanism helps the brain realign cognitive focus to immediate realities and process new information, potentially offering insights into neuropsychiatric disorders such as ADHD, PTSD, epilepsy, and Alzheimer’s disease. The study, which analyzed mouse models, found that dentate spikes in the hippocampus play a crucial role in this shift and in associating memories with sensory stimuli, opening new avenues for targeted treatments.

"Unveiling the Brain's Daydream Interruption Mechanism"

Originally Published 1 year ago — by Medical Xpress

Researchers at Boston Children's Hospital have discovered that a part of the brain called the dentate gyrus plays a crucial role in snapping our attention back from daydreaming and forming memories. This neural activity, known as dentate spikes, helps us quickly process new information and orient ourselves to our environment, as well as promote associative memory. The findings could have implications for understanding neuropsychiatric disorders such as ADHD, PTSD, and epilepsy, and may lead to new treatments for these conditions.
