Early studies of the Central Nervous System involved animal experimentation, including gradual removal of brain parts, injections of substances, and electrical stimulation on animals often without anesthesia. The antivivisectionist movement arose in response to these practices, questioning the ethics of animal experimentation.
Los estudios tempranos del Sistema Nervioso Central implicaron experimentación animal, incluyendo la remoción gradual de partes del cerebro, inyecciones de sustancias y estimulación eléctrica en animales a menudo sin anestesia. El movimiento antivivisección surgió en respuesta a estas prácticas, cuestionando la ética de la experimentación animal.
| Front | Ethics in the early studies of the Central Nervous System |
|---|---|
| Back | • Animal experimentation o Flourens & localization of function – gradually removed parts of animals brains to see how behaviors changed. o Injecting substances into brains (heated wax, corrosive substances, sodium chloride) o Stimulating brain by sending electrical current into brain of unanaesthetized animals – electrocuted animals’ brains to see what happens. Implanting electrodes in animals. o Often did not use tranquilizers, analgesics, or anesthetics • Antivivisectionist movement |
