Meningioma is a usually benign brain tumor that can cause symptoms such as seizures, headaches, and vision changes. Treatment depends on the size and location of the tumor, with surgery being the main form of treatment. Radiation therapy may be used in addition to or instead of surgery. A brain tumor meningioma is an abnormal […]
Cognitive science studies the mind and intelligence, while cognitive neuroscience studies the biological basis of cognition. Advances in brain imaging have led to a better understanding of cognitive processes and their effects on behavior. Insights gained from studying the brain and cognitive sciences have applications in education, artificial intelligence, and psychoanalysis. The brain and cognitive […]
Brain bruises can have lasting effects, including post-concussion syndrome, nerve damage, and behavioral changes. Prompt treatment is important to prevent complications and reduce the risk of permanent damage. A coup injury can cause widespread cognitive symptoms. Bleeding in the brain tissues can lead to lasting effects, such as altered consciousness, seizures, headaches, and memory loss. […]
MRI is a non-invasive medical technique that provides a 3D image of a scanned section of the body. An MRI of the brain can diagnose medical conditions affecting the area, but may cause discomfort for claustrophobic patients. There are two types of MRI machines, and some scans require an injection of a contrast solution. It […]
Brain tumors can cause headaches due to pressure on the brain and blockage of cerebrospinal fluid. Headaches caused by tumors are often described as throbbing or pressure and tend to get worse over time. However, not all headaches are caused by brain tumors and other symptoms such as vision problems and nausea may also be […]
Inoperable brain cancer is caused by malignant growth in a part of the brain that cannot be safely removed with surgery due to location, spread, or the patient’s overall health. Surgery is often used in conjunction with medication and radiation therapy, but tumors in critical areas of the brain are less likely to be treated […]
Scientists created a robot made of Lego with a software simulation of a nematode’s neural connections. The nematode’s brain controlled the robot, responding to external stimuli in the same way as a worm. Caenorhabditis elegans is a non-parasitic nematode that feeds on microbes and is commonly used in scientific studies due to its similarity to […]
Brain fingerprinting uses brain wave monitoring to determine if a subject has memories of specific facts relevant to a criminal case. It is different from a polygraph test and has been used in several high-profile cases in the US. The test measures brain waves when presented with visual or sound stimuli and can determine if […]
Nicotine, found in tobacco leaves, stimulates neurotransmitters in the brain, affecting pleasure, memory, and attention. Addicts may experience withdrawal symptoms. Nicotine’s effects may help treat Alzheimer’s and Tourette’s syndrome. Nicotine is a naturally occurring chemical found in the leaves of the tobacco plant. Many people smoke or chew tobacco products to ingest this substance. There […]
Cerebral hypoxia is a lack of oxygen supply to the brain, which can cause severe cognitive and motor impairment or even death. There are four categories of severity, and symptoms vary widely. Causes include drowning, smoke inhalation, stroke, cardiac arrest, low blood pressure, and respiratory muscle paralysis. Cerebral hypoxia is a medical term that refers […]
The brains of people with ADHD function differently, with unusual amounts of certain chemicals and neurotransmitters. Four main areas of potential ADHD brain activity are the frontal lobe, cerebral cortex, limbic system, and reticular activating system, all of which work together to produce the various aspects of ADHD. Symptoms include trouble concentrating, poor impulse control, […]
Metastatic brain cancer, also known as “secondary brain cancer,” is a serious diagnosis that requires prompt action. It originates in other parts of the body and spreads to the brain, causing neurological symptoms. Treatment options include surgery, chemotherapy, and radiation therapy. Early detection is crucial for the best prognosis. Metastatic brain cancer is a form […]
A brain fart is a moment of forgetfulness or lack of mental focus that can happen to anyone. It can be embarrassing or hurtful, but it’s a natural occurrence that most people experience at some point. The term may have originated from the bodily function of flatulence or from the medical term for a heart […]
Infant brain damage can have various causes and symptoms, including physical deformities, seizures, developmental delays, and unusual temperaments. Other indicators include jaundice, difficulty breathing, and low body temperature. Diagnosis requires medical expertise, and early identification can lead to treatment that can minimize damage. While the term “infant brain damage” can describe a wide variety of […]
The human brain uses 10-25 watts of power, equivalent to 10-25% of a 100-watt light bulb. A computer doing the same calculations would require 40 million times the energy. The brain can perform 1016 synapse operations per second with its power, while the most efficient supercomputer would need 500,000 times more energy to function in […]
Brain fever is inflammation of the brain or its membranes, causing a fever. Meningitis affects the membranes and is caused by viral, bacterial, or fungal infection, while encephalitis affects the brain and is usually caused by a viral infection. Diagnosis involves tests such as lumbar puncture, EEG, or brain biopsy. Treatment depends on the cause, […]
The modern human brain is 10% smaller than it was 40,000 years ago, with an average capacity of 5.7 cups. Brain size is not an indicator of intelligence, and theories suggest that cooperation led to a collective intelligence that cost us cranial space but gained us civilization. The sperm whale has the largest brain in […]
A birdbrain is someone who struggles to concentrate on events or conversations and is sometimes seen as stupid or flighty. The origin of the phrase is unclear, but it is thought to refer to the small size of a bird’s brain. The term can be used affectionately or insultingly depending on the context. Most people […]
Cerebral atrophy is the reduction in brain size caused by disease or aging. Generalized atrophy affects the entire brain, while focal atrophy affects specific regions. Mental exercises and drugs may delay or prevent atrophy. Diseases like Alzheimer’s and strokes can cause focal atrophy. Cerebral atrophy, also known as cerebral atrophy, refers to the reduction in […]
Cerebral infarction, or ischemic stroke, occurs when blood flow to the brain is cut off, often due to a thrombosis or embolism. The resulting ischemic cascade can cause brain tissue damage and inflammation. Symptoms include muscle weakness, numbness, and memory impairment. Treatment involves breaking or removing the clot and supportive therapy. Cerebral infarction, also known […]
