Neurologists Debunk 11 Brain Myths.

It’s fascinating how myths about the brain can persist even when scientific evidence contradicts them. Let’s dive into some of these misconceptions and clarify the facts:

We Don’t Just Use 10% of Our Brains:

The idea that we only use 10% of our brains is a common myth. In reality, brain imaging technologies have shown that the entire brain is active, even during rest or sleep. Damage to any part of the brain can have significant consequences for cognition and functioning. So, rest assured, you’re using more than just 10% of your brain!

Brain Damage Isn’t Always Permanent:

While brain damage can be devastating, the human brain has remarkable plasticity. Even after serious events like strokes, the brain can partially or fully heal itself over time by forming new connections. Recovery depends on factors like severity and location of the injury. A concussion from a football game may heal with time, while severe strokes can lead to more lasting damage.

People Aren’t Fully Right- or Left-Brained:

The notion that people are either “right-brained” (creative) or “left-brained” (analytical) is a simplification. Brain lateralization does exist, but we engage both hemispheres for most tasks. Our brains work best when they collaborate across regions, even for activities typically associated with one side.

IQ Tests Aren’t the Whole Story:

IQ tests measure specific cognitive abilities but don’t capture overall intelligence comprehensively. Factors like social intelligence, emotional intelligence, and individual talents play a significant role in determining a person’s abilities.

Education and Individuality Matter:

Education, broadly defined, contributes to skill development. Not everyone follows the same path, and some people excel in unique ways. We’re all individuals with diverse talents and aptitudes, so it’s essential to recognize and appreciate those differences.

Brain Function and Lobes:

Our brain is a complex organ with different regions responsible for various functions. The frontal lobe handles motor function, language, and executive planning. The parietal lobe is involved in sensory processing. The occipital lobe processes visual information. The temporal lobe plays a role in memory and language comprehension.

Brain Stem and Cerebellum:

The brain stem controls essential functions like arousal, breathing, and heart rate. The cerebellum is crucial for motor control and coordination.

Video Games and Brain Health:

Contrary to the myth, video games don’t “rot” your brain. In fact, certain games can be beneficial. Games that focus on teamwork, problem-solving, and strategy can enhance cognitive skills. Surgeons even use video game simulators to practice fine motor skills!

Defining “Too Much” Video Gaming:

While there’s no strict definition, studies suggest that 12 to 90 hours per week is acceptable. However, moderation is essential. Spending excessive time gaming might impact other aspects of life.

Memory and Aging:

As we age, certain aspects of memory change. While some memory functions may decline, others can improve or remain stable. Semantic memory (knowledge of facts and concepts) tends to remain strong. Episodic memory (memory of specific events) may decline, especially recent events like where you put your keys.

Left Brain vs. Right Brain:

The idea that people are either left-brained (logical) or right-brained (creative) is a myth. Brain hemispheric dominance varies, but it doesn’t determine creativity or logic. Both sides work together for various functions.

Stroke Prevention:

You’re absolutely right! We can take steps to prevent strokes: Manage risk factors: Control high blood pressure, quit smoking, manage cholesterol, and address diabetes. Maintain cardiovascular health: Regular exercise, a healthy diet, and weight management contribute to overall well-being. Recognize stroke symptoms: The FAST mnemonic (Facial droop, Arm weakness, Slurred speech, Time to call 911) helps identify strokes early.

Fish and Brain Health:

While fish won’t necessarily make you smarter, it does offer significant benefits for brain health. Regular fish consumption, especially fatty fishlike herring, mackerel, salmon, sardines, and tuna, provides essential omega-3 fatty acids (EPA and DHA). These omega-3s support cognitive health, reduce inflammation, and may help protect delicate blood vessels in the brain1234.

Senses and Perception:

Our senses are not always objective. They can be influenced by emotions, memories, and individual differences. Pain tolerance, visual perception, and other sensory experiences vary from person to person. Remember the famous “blue dress vs. black dress” debate? Perception can indeed differ among people.

Gender and Brain Structure:

Brain structure is not inherently gender specific. Regardless of gender identity or sexual orientation, we all have similar brains. Studies have shown that emotional pathways and cognitive styles are shaped by experiences, not biological sex. As we age and encounter different influences, our brain structures adapt and develop.

Seizures and Epilepsy:

A seizure occurs due to hyper synchronization of brain cells, leading to abnormal electrical activity. Epilepsy is a condition characterized by recurrent seizures. It’s essential to seek medical evaluation if you experience seizures to determine the cause and appropriate management. When neurons fire excessively or synchronously, it disrupts normal brain function. Epilepsy, on the other hand, is a chronic neurological disorder characterized by recurrent seizures. It’s essential to differentiate between a single seizure and epilepsy.

Understanding Seizures:

Seizures can take various forms, from violent shaking (like tonic-clonic seizures) to subtle moments of altered consciousness (like absence seizures). Causes of seizures include fever, head injuries, infections, metabolic issues, and more. Not all seizures lead to epilepsy. If you experience two or more seizures, you may be diagnosed with epilepsy.

Seeking Medical Evaluation:

If you’ve had your first seizure or experience recurrent seizures, consult a neurologist. Diagnostic tests like EEG (electroencephalogram) and MRI (magnetic resonance imaging) help identify abnormalities in brain waves and structure. Taking prescribed medications consistently is crucial for managing epilepsy.

Seizure Safety Tips:

During a seizure, remain calm and protect the person by placing a cushion under their head and laying them on their side. Avoid putting anything in their mouth or moving them to another room. Call 911 if it’s their first seizure, lasts longer than 5 minutes, or if they’re injured or pregnant.

Brain Health Matters:

You only get one brain, so take care of it! Communicate openly with your doctor and follow their advice. Remember, there’s a grain of truth in many myths, but accurate information is essential for your well-being.
