Neuroscience is the scientific study of the nervous system, encompassing its structure, function, development, genetics, biochemistry, physiology, pharmacology, and pathology. It is an interdisciplinary field that collaborates with other disciplines such as biology, medicine, psychology, computer science, chemistry, and philosophy. The ultimate goal of neuroscience is to understand the biological mechanisms by which the nervous system mediates behavior, cognition, and emotion.
Pareidolia is a psychological phenomenon where individuals perceive familiar patterns, such as faces or objects, in random stimuli. This tendency is rooted in the brain's pattern recognition capabilities and has been observed across various cultures and historical periods.

Psychoanalysis is a theory of mind and a method of psychological treatment originating in the 1890s with the work of Austrian physician Sigmund Freud. It emphasizes unconscious mental processes, conflict, and symbolic meaning, employing techniques such as free association, dream interpretation, and analysis of transference in intensive, multi‑session therapeutic settings. The field subsequently diversified into multiple schools and institutions and remains the subject of ongoing empirical evaluation and philosophical debate.
