Ch. 12 The Central Nervous System
Chapter 12, Problem 12.2a

Mark the following statements about the brain as true or false. If a statement is false, correct it to make a true statement.




a. Humans use only 10% of their brains.

Verified step by step guidance
1
Identify the statement to be evaluated: 'Humans use only 10% of their brains.'
Understand the common myth: The statement is based on a popular myth that suggests humans only utilize a small portion of their brain's capacity.
Consider scientific evidence: Research in neuroscience shows that almost all parts of the brain have a known function and are active at different times, even during simple tasks.
Evaluate the statement: Based on scientific understanding, the statement is false.
Correct the statement: A more accurate statement would be 'Humans use all parts of their brain, and different areas are active at different times depending on the task.'

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Brain Utilization Myth

The idea that humans only use 10% of their brains is a myth. Neuroimaging studies show that virtually all parts of the brain have a known function and are active at different times, depending on the tasks being performed. This misconception likely arose from misinterpretations of neurological research and has been perpetuated in popular culture.

Major Regions of the Brain

Neuroplasticity

Neuroplasticity refers to the brain's ability to reorganize itself by forming new neural connections throughout life. This adaptability allows the brain to compensate for injury, learn new information, and adjust to new experiences. Understanding neuroplasticity is crucial for recognizing how the brain can change and develop beyond the simplistic notion of limited usage.

Brain Functionality

Different regions of the brain are responsible for various functions, such as movement, sensation, emotion, and cognition. The brain operates as a complex network where multiple areas work together to perform tasks. Recognizing the diverse roles of brain regions helps clarify why the 10% usage claim is misleading, as all parts of the brain contribute to our overall functioning.
