Nestled in southwestern France the Lascaux Cave, discovered in 1940, boasts some of the most breathtaking prehistoric artwork, recognized by archaeologists. This collection of paintings dating back approximately 17,000 years to the Upper Paleolithic era showcases the remarkable cognitive and artistic talents of early humans. The cave's walls feature over 600 images including strikingly realistic representations of animals like horses, bison, and deer alongside abstract symbols. This artistic expression not only reflects an appreciation for aesthetics but also an early grasp of storytelling and symbolism offering insights into the minds of our ancestors. However, what facilitated the creation of such masterpieces by prehistoric individuals? Studies in neurology and anthropology indicate that a blend of intricate brain functions, social behaviors and cognitive progressions played a role.

The journey through neuroscience unveils a shift from philosophical theories to scientific inquiries. The understanding of brain functionality evolved from speculations, about the mind and body moving towards insights into the brain's structure and operations. This progression reflects our expanding knowledge of how the brain shapes thoughts, actions and communication, spanning from Descartes dualism to Broca and Wernickes discoveries in language processing.

Maria Mikhailovna Manasseina (1843–1903) was a female doctor who graduated in Europe. She made notable contributions to fields like biochemistry, physiology and the study of sleep deprivation. Manasseina pioneered the idea that the effects of sleep deprivation stem from the brain emphasizing that sleep plays a role in sustaining life compared to food. In 1889 she published a comprehensive handbook on sleep in Russian. Which later got translated into English and gained popularity in Europe serving as an important reference on the topic. Challenging the belief that sleep was simply an inactive state of the brain Manasseina suggested it represented a unique form of brain activity. This perspective was particularly insightful since the technology for measuring brain activity through electroencephalography wouldn't emerge for two decades. Before exploring sleep she conducted research at the Polytechnic University of Vienna where she studied fermentation and discovered that it resulted from compounds extracted from yeast cells rather than from the yeast itself. Although Eduard Buchner confirmed these findings later in time he failed to credit Manasseina's work in his publications despite his knowledge of it. Buchner was awarded the Nobel Prize in Chemistry in 1907 for this discovery while Manasseina's accomplishments sadly remained overlooked, forgotten.
