New research may upend our understanding of the brain, showing that travelling waves of neuronal excitation dominate the activity associated with our thoughts and feelings.
Transcranial alternating current stimulation, or tACS, is a type of brain stimulation that can change neural activity and improve memory, attention and executive function.
Pain has long been subjectively measured, leading to frustrations for patients and doctors alike. Identifying neural biomarkers of pain could improve diagnosis and lead to better treatments of chronic pain conditions.
One genetic study of over a quarter million people highlights the cognitive benefits of exercise, while another, based on 30 years of scientific literature, says the opposite. Who’s right and who’s wrong?
Adolescent brains are especially vulnerable to risk-taking and social pressure. But there are steps parents can take to steer their teen away from dangerous social media stunts.
People with aphantasia are unable to deliberately bring to mind mental images. Understanding the mechanisms of aphantasia reveals that different types of cognition exist.
Pinpointing where memories are stored in the brain and how they are transmitted could provide new targets to treat neurological diseases and serve as models for neuromorphic computing.
Learning new rules requires the suppression of old ones. A better understanding of the brain circuits involved in behavioral adaptation could lead to new ways to treat schizophrenia and bipolar disorder.
Neuroscientists have typically thought of energy supply to the brain as demand-based. A supply-limited view offers another perspective toward aging and why multitasking can be difficult.
Parents provide the energy needed for their young to grow large brains. Climate change may negatively affect birds’ brain development as it impacts food supplies.
