Lesson 2 so NSCI 175 - UNC

The Golgi Method, what is true? - select all that apply

• Silver nitrate based stain

• Stains only a few, random
  neurons in their entirety

• Stains all neurons in a tissue sample uniformly

• Developed to visualize neurotransmitter activity in live neuron

Why is the Golgi methods ability to stain only a few random neurons in their entirety advantageous

• Other cells do not interfere which allows for detailed observation of individual neurons

• It provides detailed information about the chemical composition of neurons

• It enhances the study of neuronal activity by showing which neurons are active

• It allows for the visualization of neuron-to-neuron communication at the synaptic level

The Neuron Doctrine - who's associated with this?

Reticular Theory - who's associated with this?

Suggests that
neurites of different neurons are
continuous with each other (fused) to
form a continuous network

• Synaptic theory

• The Neuron Doctrine

• Reticular Theory

• Axonal theory

The neurites of different neurons are not
continuous with each other and
communicate by contact, not continuity

• Electrical synapse theory

• The Neuron Doctrine

• Reticular Theory

• Chemical synapse theory
