Main organ of the nervous system, controls all bodily activities and interprets inputs from the outside world
Brain
Made up of billions of neurons that form circuits and networks, which control the flow and information within nervous system
What the brain controls
Intelligence
Creativity
Emotions
Memories
Cerebrum
Largest part of the brain, composed of right and left hemisphere, interprets touch, vision, and hearing, responsible for speech, reasoning, emotions, learning, and small body movements
Cerebellum
Located under the cerebrum, coordinates muscle movements and maintains composure and balance
Brain stem
Acts as "relay center" between the brain and the spinal cord, responsible for automatic functioning such as breathing, heart rate, body temperature, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing
Four lobes of the cerebrum
Frontal lobe
Parietal lobe
Occipital lobe
Temporal lobe
Frontal lobe
Largest lobe, responsible for personality, behavior, judgement, planning, problem solving, intelligence, speech, and body movement
Parietal lobe
Interprets language and words, aids visual recognition and spatial relationships, involved in pain and touch perception
Occipital lobe
Involved in vision and movement
Temporal lobe
Responsible for short-term memory, speaking, musical rhythm, and some degree of smell identification
Limbic system
Group of brain structures that help with emotions, behavior, motivation, long-term memory, and olfaction (smelling)
Structures of the limbic system
Helps in learning, memory, navigation, and spatial perception
Linked to brain's reward system, stress, and "fight or flight" reaction
Sits above pituitary gland and transmits chemical messages to control its functions
Helps regulate emotion, behavior, pain, and autonomic motor functions
Importance of cerebrum and limbic system
Cerebrum plays important role in thinking, limbic system has to do with emotions, which shape reactions and define personality
Left brain
Logic, sequencing, language, rational thinking, mathematics, facts, thinking in words
The two hemispheres of the brain function are crucial to understanding personality, recognizing left and right brain processes helps adjust study habits
Mind mapping
Powerful graphic technique that provides a universal key to unlock the brain's potential, uses all brain skills - word, image, number, logic, rhythm, color, and spatial awareness
Uses of mind mapping
Taking notes
Brainstorming
Presenting information
Boosting creativity
Planning
Research preparation
Reviewing a lesson
Mind mapping has numerous benefits such as improving ability to learn meaningfully, helping memorization and information retention, making complex things easier to understand, and increasing productivity and creativity
Steps in mind mapping
1. Start with main idea/subject and write it at center
2. Add branches for subtopics/themes
3. Color code branches and subtopics
4. Include images, icons, and visual aspects
Mind mapping for left-brain vs right-brain dominant individuals
Left-brain: topics linked to language, logic, arithmetic, reasoning
Right-brain: creativity, emotions, colors, images
Mental health
Characterized by emotional well-being, coping with stress and everyday obstacles, the absence of mental illnesses, and the capability to establish positive relationships
According to the World Health Organization (2020), half of all mental health problems begin at the age of 14
