The corpus callosum is the thick band of nerve fibers that connects the left and right hemispheres of the brain, acting like a superhighway to allow communication between the two sides. Given its role in integrating information, researchers have long speculated that the size and structure of the corpus callosum may be linked to intellectual …
Phrenology, the pseudoscience of linking personality traits to head shape, has captivated minds for over 200 years despite lacking empirical evidence. A recent study took a novel approach to finally settling the debate – utilizing modern neuroimaging and big data to rigorously test phrenological claims. The results provide a definitive refutation of phrenology’s core premise. …
Researchers have long suspected that brain size affects intelligence, with people who have bigger brains tending to have higher IQs. A new set of studies provides compelling evidence that this relationship is likely causal and not just correlational. Key Takeaways: Among siblings, the one with the larger brain size tends to have the higher IQ. …
Neuralink, a neurotechnology company founded by Elon Musk, has developed a novel brain-machine interface system with unprecedented electrode density and bandwidth. In a recent white paper, Neuralink scientists describe their progress towards a scalable, high-performance implantable device for interfacing with the brain. The key facts: Neuralink’s device has over 3,000 electrodes per array, an order …
Neuralink, a neurotechnology company founded by Elon Musk in 2016, is developing an innovative brain-machine interface (BMI) device that aims to enhance brain function and revolutionize neurosurgery. Early testing on animals shows promise, but human trials are still needed to determine safety and efficacy. If proven viable, Neuralink’s technology could transform treatment for neurological disorders. …
Neuromodulation techniques that stimulate the nervous system through electric current are revolutionizing the treatment of neurological and psychiatric disorders like depression, movement disorders, and chronic pain. These techniques allow for precisely targeted treatment of specific brain regions. Key facts: Neuromodulation techniques include invasive methods like deep brain stimulation (DBS) as well as non-invasive methods like …
Borderline personality disorder (BPD) is a complex mental health condition characterized by difficulties with emotional regulation, impulsivity, and unstable relationships. A key feature of BPD is impaired empathy, which contributes to the interpersonal dysfunction seen in these patients. A new review analyzes 45 studies on empathy and related constructs like theory of mind in BPD, …
Depression affects over 120 million people worldwide, carrying a heavy burden of disability, mortality, and cost. While medications like SSRIs have provided relief for many, most patients fail to achieve full remission. After 30 years with few advances in pharmaceutical options, it may be time to rethink our approach to treating depression. Exciting new research …
Cold stimulus headache, commonly known as “brain freeze”, is a curious and understudied phenomenon that many of us have experienced when eating or drinking something cold too quickly. Though brief and benign, these headaches provide insight into how the brain responds to sudden temperature changes. Key Facts About “Brain Freeze”: Caused by quick exposure of …
Pineal gland calcification, the buildup of calcium deposits in the pineal gland, is surprisingly common, affecting over 60% of the population according to a new meta-analysis. This concerning condition can disrupt proper pineal gland functioning and melatonin secretion, potentially contributing to an array of health issues. Key Facts: The pineal gland regulates circadian rhythms through …
