Dehumanization can occur discursively (e.g., idiomatic language that likens individual human beings to non-human animals, verbal abuse, erasing one's voice from discourse), symbolically (e.g., imagery), or physically (e.g., chattel slavery, physical abuse, refusing eye contact).
Transhumanists are often concerned with methods of enhancing the human nervous system. Though some, such as Kevin Warwick , propose modification of the peripheral nervous system , the brain is considered the common denominator of personhood and is thus a primary focus of transhumanist ambitions.
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.
The vertebrate central nervous system (CNS) is derived from the ectoderm—the outermost germ layer of the embryo. A part of the dorsal ectoderm becomes specified to neural ectoderm – neuroectoderm that forms the neural plate along the dorsal side of the embryo.
One such region is the nucleus accumbens—a key part of the brain’s reward system that’s fueled by dopamine, a chemical that Wise fondly refers to as “the slutty neurotransmitter” because ...
The function of the brain and nervous system is to protect us from being overwhelmed and confused by this mass of largely useless and irrelevant knowledge … leaving only that very small and special selection which is likely to be practically useful.’ According to such a theory, each one of us is potentially Mind at Large.
Computational neuroscience includes both the study of the information processing functions of the nervous system, and the use of digital computers to study the nervous system. It is an interdisciplinary science that links the diverse fields of neuroscience, cognitive science and psychology, electrical engineering, computer science, physics and ...
