Understanding your brain

What do different parts of the brain do ?


Your brain is an incredibly complex organ responsible for various functions, and different parts play specialised roles in controlling different aspects of our behaviour, thoughts, and body functions. Here's a simple breakdown of some major regions of your brain and their functions:-


  1. Cerebrum:

  • Frontal Lobe: Controls voluntary movement, reasoning, problem-solving, planning, decision-making, and emotions.

  • Parietal Lobe: Processes sensory information like touch, temperature, and pain. Also involved in spatial awareness and perception.

  • Temporal Lobe: Manages auditory processing, memory, language, and some aspects of emotion and learning.

  • Occipital Lobe: Primarily responsible for vision and visual processing.

  1. Cerebellum:

  • Coordinates voluntary movements and balance. It's crucial for motor skills and learning new movements.

  1. Brainstem:

  • Medulla Oblongata: Regulates basic functions like heartbeat, breathing, swallowing, and blood pressure.

  • Pons: Assists in regulating breathing, sleep cycles, and some aspects of facial movement.

  • Midbrain: Manages sensory reflexes, eye movement, and some involuntary motor responses.

  1. Hippocampus:

  • Critical for memory formation, especially converting short-term memory to long-term memory.

  1. Amygdala:

  • Plays a key role in processing emotions, particularly fear and pleasure responses.

  1. Hypothalamus:

  • Regulates thirst, hunger, body temperature, and controls the pituitary gland, which in turn governs hormone release.

  1. Thalamus:

  • Acts as a relay station for sensory information, directing it to the appropriate regions of the cerebrum for further processing.

  1. Prefrontal Cortex:

  • Involved in complex cognitive behaviour, personality expression, decision making, and moderating social behaviour.


Each of these regions doesn't work in isolation; they often communicate and collaborate to execute various functions. Additionally, advancements in neuroscience continue to uncover deeper insights into how these regions interact and their involvement in more intricate processes.

Understanding the brain's complexity helps us appreciate its role in shaping our experiences, behaviour, and overall well-being.
