Structure of the Brain

Structure of the Brain

• Cerebrum: largest part of the brain, divided into two hemispheres (left and right)
• Cerebellum: located at the base of the brain, responsible for coordination and balance
• Brainstem: connects cerebrum and cerebellum to the spinal cord, regulates basic functions (breathing, heart rate, blood pressure)

Brain Regions

• Frontal lobe: decision-making, problem-solving, motor control
• Parietal lobe: processes sensory information from the body
• Temporal lobe: plays a role in hearing, memory, and language
• Occipital lobe: primary visual processing
• Hippocampus: involved in forming and consolidating new memories

Neurons and Synapses

• Neurons: specialized cells that transmit information
• Dendrites: receive signals from other neurons
• Axon: carries signals away from the cell body
• Synapses: gaps between neurons where chemical signals are transmitted
• Neurotransmitters: chemicals released by neurons to transmit signals

Brain Functions

• Cognition: perception, attention, memory, learning, language
• Motor control: voluntary movements, such as walking and talking
• Emotions: emotional responses, such as fear and happiness
• Regulation: controls body functions, such as heart rate and blood pressure

Brain Development and Plasticity

• Neuroplasticity: brain's ability to reorganize and adapt throughout life
• Synaptic pruning: elimination of unnecessary neural connections
• Myelination: process of insulating neurons to increase transmission speed
• Neurogenesis: growth of new neurons in certain parts of the brain

IQ Testing

• IQ testing is a method to assess an individual's ability to provide meaningful responses, comprehend information, and solve problems effectively compared to the general population.
• It measures cognitive abilities, including the capacity to make logical decisions and process information.

Jordan Peterson IQ Test

• The Jordan Peterson IQ test is based on his intellectual measurement technique, developed in collaboration with trained psychologists.
• This test provides a realistic IQ test experience, accurately measuring cognitive abilities.
