Leptin is a hormone that regulates appetite and energy expenditure.

Emotions can be inferred from physiology (e.g., heart rate), behavior (expressions), and self-report (e.g., surveys).

Emotions are a result of physiological responses to events.

Emotions and physiological responses occur simultaneously.

Emotions arise from a combination of physical arousal and cognitive appraisal.

Self-reported emotions can be inaccurate due to biases and lack of awareness.

Lie detectors measure physiological responses (like heart rate) to assess deception, assuming emotional responses differ between truth and lies.

Facial expressions may be innate and universal, yet cultural factors can influence their interpretation.

A smaller hippocampus has been linked to various memory disorders, including Alzheimer's disease and PTSD. This structure is crucial for forming new memories and recalling them.

The amygdala plays a key role in processing and storing emotional memories, particularly those linked to fear and anxiety. Its involvement leads to stronger, more vivid, and enduring emotional memories compared to neutral ones.

Language, as a complex system of symbols and rules for communication, is often considered the defining characteristic of human intelligence. Unlike animal communication, language allows for abstract thought, displacement (talking about things not present), and infinite creativity.

Specific brain regions are dedicated to language processing. Broca's area is crucial for language production and speech, while Wernicke's area is responsible for language comprehension and understanding.

Language influences our thoughts, not just by expressing them. It shapes our perception, reasoning, and memory. The structure of language influences the way we organize and process information.

The limbic system, responsible for emotions, is tightly connected to the cortex, responsible for higher-level thinking. This allows for quick emotional responses to stimuli and impacts decision-making.

The Wada test is a medical procedure that temporarily numbs one hemisphere of the brain to assess language and memory functions. By observing the effects on various cognitive tasks, researchers understand the specialization of each hemisphere.

The left hemisphere is associated with positive emotions like laughter and indifference. It's also linked with logic, language, and analytical thinking.

The right hemisphere is linked to negative emotions like sadness, fear, and anger. It's also associated with creativity, intuition, and spatial reasoning.

Neurotransmitters like serotonin and dopamine play crucial roles in emotions. Serotonin affects mood and aggression, while dopamine influences motivation and reward.

Oxytocin, often called the 'love hormone,' plays a role in bonding, trust, and social behavior. It promotes lactation and maternal care in mammals.

Learning is the process of acquiring new knowledge or skills. Memory is the storage and retrieval of that information. Learning forms new connections in the brain, creating memories.

The cerebellum, located at the back of the brain, is responsible for coordinating movement, balance, and motor learning. It also stores implicit memories, like procedural skills.
