Fact-check status: passed

The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

• The human brain is the control center for thoughts, emotions, and actions, interpreting sensory input and processing memories[2].
• Neurons communicate via electrical and chemical signals to form networks that influence behavior[2].
• The cerebrum is responsible for higher cognitive functions like reasoning, problem-solving, and creativity[2].
• The left brain hemisphere is associated with logic and language, while the right hemisphere is linked to creativity and spatial awareness[2].
• The limbic system, including the amygdala and hippocampus, plays a critical role in emotional processing and memory formation[2].
• Dopamine is the neurotransmitter that drives motivation, reward-seeking behavior, and pleasure, and plays a pivotal role in habit formation[2].
• Memory formation involves synaptic plasticity, where connections between neurons strengthen with repeated use[2].
• The hippocampus consolidates short-term memories into long-term memories by integrating perceptions into a single experience[7].
• The central executive network (CEN) is an externally driven system paramount for attention control, working memory, and goal-directed behavior[1].
• The brain constantly selects relevant input and suppresses irrelevant or distracting information through attention management[1].
• Learning changes the physical structure of the brain and organizes its functional organization[3].
• Autonomic brain functions include the rhythmic regulation of heart rate and breathing to maintain homeostasis[8].
