Question

what did camillo golgis \black reaction\ technique make possible for scientists to see? the entire structure of a neuron, including its cell body and branches the electrical activity of neurons in real time the chemical neurotransmitters released between neurons the brains division into different lobes what discovery in the mid - 1900s supported cajals neuron doctrine? functional mri scans showed changes in blood flow eegs detected brain wave activity pet scans traced chemical metabolism in the brain electron microscopy revealed membranes separating individual neurons

Explanation:

Camillo Golgi's "black reaction" (Golgi staining) allowed visualization of the entire neuron structure. Electron microscopy in the mid - 1900s supported Cajal's neuron doctrine by showing membranes separating neurons, indicating they are individual cells.

Answer:

1. The entire structure of a neuron, including its cell body and branches
2. Electron microscopy revealed membranes separating individual neurons
