Understanding Brain Function: The Key to Unlocking Your Mind’s Potential

Have you ever stopped to think about what an incredible organ your brain is? It controls everything from your thoughts, emotions, movement, and coordination, to your 5 senses – sight, hearing, taste, smell, and touch. The brain is responsible for making sure our body functions as it should. In fact, it’s the most complex organ in the human body, boasting over 100 billion nerve cells (neurons) connected by trillions of synapses.

In this blog post, we’ll explore the 10 different functions of the brain, the six essential parts of the brain, and how each part contributes to the overall functioning of the brain. We’ll also answer some of the most frequently asked questions about the brain, including What are the 7 functions of the brain?, What is the most important function of the brain?, and What is the function of the brain in psychology?

The 10 Functions of the Brain

The brain is responsible for numerous functions that ensure our wellbeing and survival. These functions include:

  1. Movement – To move our body in response to external stimuli e.g., walking, running, jumping, or cycling.
  2. Sensation – To perceive external stimuli through the five senses (sight, sound, touch, taste, and smell).
  3. Cognition – To process and interpret external stimuli e.g., remembering, decision-making, and planning.
  4. Emotion – To regulate our emotions and emotional responses to various stimuli.
  5. Attention – To focus and pay attention to relevant stimuli while filtering out distractions.
  6. Memory – To store and retrieve information from past experiences.
  7. Language – To communicate through speaking, writing or any other relevant means.
  8. Perception – To interpret sensory information and create a meaningful representation of the world around us.
  9. Consciousness – To be aware of oneself and the surrounding environment.
  10. Homeostasis – To maintain internal physical and chemical balance.

The 6 Parts of the Brain and Their Functions

The brain is divided into six parts, each with its distinct purpose and function:

  1. Cerebrum: It’s the largest and most complex part of the brain, responsible for conscious thoughts and voluntary reactions.
  2. Cerebellum: It maintains body coordination, balance, and posture.
  3. Brainstem: It controls essential body functions such as breathing, heartbeat, and blood pressure.
  4. Limbic System: It regulates emotions, memory, and the autonomic nervous system.
  5. Thalamus: It relays sensory and motor signals to the cerebral cortex and controls sleep and alertness.
  6. Hypothalamus: It regulates hunger, thirst, body temperature, and controls the release of hormones from the pituitary gland.


The cerebrum is the most critical part of the brain and is divided into two hemispheres – the left hemisphere and the right hemisphere. They communicate through a collection of fibers called the corpus callosum. The left hemisphere is responsible for logical thinking, language, and analytical processes. The right hemisphere, on the other hand, controls creativity, imagination, and artistic perception. The cerebrum is further divided into four lobes, each responsible for various functions:

  • Frontal Lobe:

    It’s responsible for planning, decision-making, reasoning, personality traits, and movement coordination.

  • Temporal Lobe:

    It’s responsible for processing sound and speech, memories, and language comprehension.

  • Parietal Lobe:

    It’s responsible for processing sensory information such as touch, pressure, temperature, and pain.

  • Occipital Lobe:

    It’s responsible for processing and interpreting visual information from the eyes.


The cerebellum, located beneath the cerebrum, primarily controls voluntary movements, balance, and coordination. It has two hemispheres connected by the vermis. The cerebellum receives information from the inner ear, eyes, and body’s muscles and joints and regulates movement accordingly.


The brainstem connects the brain and the spinal cord, controlling vital body functions such as breathing, swallowing, heartbeat, and blood pressure. It’s composed of three parts – the midbrain, pons, and medulla oblongata. The midbrain controls movement, vision, and hearing, while the pons manages communication between different parts of the brain and the medulla oblongata controls involuntary processes like breathing and digestion.

Limbic System

The limbic system is responsible for regulating emotions, memory, and the autonomic nervous system. It includes the hippocampus, amygdala, and hypothalamus. The hippocampus stores new memories, the amygdala regulates emotions such as fear, and the hypothalamus manages hormone release, hunger, thirst, and body temperature.


The thalamus is located above the brainstem and is responsible for relaying sensory and motor information to and from the cerebral cortex. It’s also responsible for regulating sleep and alertness.


The hypothalamus is a small organ located below the thalamus. It regulates hunger, thirst, body temperature, and controls the release of hormones from the pituitary gland.

Frequently Asked Questions About Brain Function

What are the 7 Functions of the Brain?

The seven functions of the brain are movement, sensation, cognition, emotion, attention, memory, and language.

What is the most important function of the brain?

All the functions of the brain are interconnected and equally important. However, the most critical functions include breathing, heartbeat, and maintaining the body’s internal balance (homeostasis).

What is the function of the brain in psychology?

The function of the brain in psychology involves understanding how the brain affects our mental processes and behaviors.

What are the brain’s 3 major functions?

The brain’s three major functions are sensing the environment, interpreting sensory information, and controlling the body’s response to stimuli.
