One of those stuctures he named was the cingulate gyrus, outlined in his life's opus work, Vom Baue und Leben des Gehirns¹. This three-volume masterpiece summarized the neuroscience discoveries he made in his lifetime.

Other structures included in the manual were the caudate nucleus, the red nucleus, the lamina terminalis and the fasciculus cuneatus¹. The cingulate gyrus is a part of the limbic system that helps process emotions and regulate behavior².

He believed that this consciousness came along with the thalamus, which is seated directly in the middle of the brain.

We now know today that the thalamus plays an essential role in the limbic system, relaying and integrating large amounts of sensory and motor information¹, which confirms Carpenter's suspicions that the thalamus was the hub for neural activity.

His discovery that every nerve fiber emerges from a single nerve cell was essential to the development of the neuron theory¹.

However, his discovery that this artifact is focused on is his naming of the hypothalamus. After he named it in 1893, famous scientist Ramon Cajal would discover the connection between the hypothalamus and the posterior pituitary gland, and these discoveries laid the groundwork for successful scientific discovery and advancement of knowledge in the hypothalamus that continued well into the twenty and twenty-first centuries².

During this time period, the hippocampus as we know today was divided into two parts, the hippocampus major and the hippocampus minor¹.

The hippocampus became a center of great human evolutionary debate as celebrated anatomist and paleontologist Richard Owen and Thomas Henry Huxley, who used Darwinism to explain that the human brain and ape brains both had a hippocampus  minor, as the great debate was about whether or not humans evolved from apes¹.

Patrick and Dr. J. Allen Gilbert did an experiment in which they studied an individual who was actively derived of sleep. They measured his reaction times and grip strength evert six hours as time elapsed and found that sleep propensity, or the readiness to transmit from wakefulness to sleep cycled at a period of 24 hours¹. This study, released in 1896, added heavily to the research being done in this time period about the limbic system and its involvement in sleep and circadian rhythms².

He did extensive research on the limbic system, and published a work in 1878 entitled, "Comparative anatomy of the cerebral circumvolutions: The great limbic lobe and the limbic fissure in the mammalian series"¹. This work explained how there must be certain connections between each lobe of the brain. This was a monumental piece of Neuroscience history, and its impact on the science has been enormous¹.

This new method of hippocampal-avoidance proved to better preserve the patients' cognitive function and showed similar cancer control outcomes as the traditional whole-brain therapy¹.

This research is truly monumental for brain cancer treatment because in the past, radiation therapy proved to decrease the function of the hippocampus and memory after treatment¹. The results from this 2018 trial could have a significant impact on the future of cancer treatment.
