Apr 6, 2019 · Leonardo da Vinci (1452–1519) contributed to the study of the nervous system. His earliest surviving anatomical drawings (circa 1485–93) included studies of the skull, brain, and cerebral ventricles. These works reflected his efforts to understand medieval psychology, including the localisation of sensory and motor functions to the brain. He was also the first to pith a frog, concluding ...

It is the most evolutionarily advanced part of the brain. [67] Greater surface area of the brain is linked to higher intelligence as is the thicker cortex but there is an inverse relationship—the thicker the cortex, the more difficult it is for it to fold. In adult humans, thicker cerebral cortex has been linked to higher intelligence. [67]

Oct 25, 2018 · Thus, Brodmann was immersed in this world of Darwinian ideas. His efforts in comparative neuroanatomy and embryology to understand the organization of the structure in the adult brain reflect Haeckel’s influence on his work during the following 20 years. One of Haeckel’s most famous statements is that ontogeny recapitulates phylogeny.

Feb 3, 2022 · Cajal started from the assumption – which would not be scientifically proven until the 1950s – that neurons in the brain are in touch, but do not touch each other. Known as the neuron doctrine, it states that every neuron in the brain is separate and that neurons communicate across synapses. In 1906, Cajal and Golgi were jointly awarded the ...
The brain as a radiator. In 335 BC, Greek philosopher Aristotle thought the brain was simply a radiator that kept the all-important heart from overheating. Around 170 AD, Roman physician Galen suggested the brain’s four ventricles (fluid-filled cavities) were the seat of complex thought, and determined personality and bodily functions.
