Study Notes
Camillo Golgi and Santiago Ramón y Cajal
- Golgi developed a tissue-staining technique using silver nitrate, improving nerve cell visibility under a microscope.
- Golgi initially supported the reticular theory, believing nerve fibers formed a continuous network.
- Cajal, using Golgi's technique, meticulously observed nerve cells in various tissues, drawing them with great detail.
- Cajal's work refuted the reticular theory, demonstrating that neurons are discrete cells with specific connections.
- He co-founded the neuron doctrine in 1889: asserting the basic unit of the nervous system consists of individual neurons.
- Neurons are connected through synapses, not a continuous network.
- Cajal and Golgi jointly received the Nobel Prize in 1906, despite Golgi's continued support of the reticular theory.
- Cajal depicted nervous systems using detailed drawings, significantly enhancing scientific understanding.
Neuron Doctrine
- The neuron doctrine proposes neurons are discrete cells, each with a specific structure and connections.
- Neurons allow transmission of signals across gaps called synapses.
- Neurons influence each other through electrical and chemical signals.
