Brain Structure and Function

Understanding the Brain: Key Functions and Structures

The brain consists of three primary parts: the cerebrum, cerebellum, and brainstem. The cerebrum, the largest section, is divided into left and right hemispheres and is responsible for critical functions such as:

• Interpreting sensory information (touch, vision, hearing)
• Managing emotions and fine motor control
• Facilitating speech, reasoning, and learning

Key Cognitive Functions:

• Attention and concentration
• Self-monitoring and organization
• Motor planning and initiation
• Awareness of abilities and limitations
• Personality and mental flexibility
• Behavioral inhibition
