Used golgi stain on brains of newborn animals b/c density of newborn brain cells is idea that individual, non-continuous cells transmit signals in nervous system. Ramon y cajal thin slice of brain tisue immersed in silver nitrate fewer than 1% cells were completely stained small as cmpared to densityin the adult brain. Nerve net made of individual units connected together. Metabolic center of neuron that keeps cell alive. Cajal"s understanding of neurons long processes that transmit signals to other neurons receive signals from other neurons. Building blocks and transmitters of the nervous sytem. Neurons only form connctions with specific neurons called neural circuits specialized receptors pick up info. from environment (e. g. , neurons in eyes, ears nostril etc. ) The person who made this cellular study of mental life possible . Difference in potential between tips of 2 electrodes is ~70 mv. Difference continues ala neuron is at rest.
