Who is Luigi Galvani?
The thick tract of axons that connects the left and right hemispheres
What is the corpus callosum?
Italian scientist who developed a silver staining technique that allowed individual neurons to be visualized.
Who is Camillo Golgi?
The junction where two neurons meet.
What is the synapse?
The false theory that brain cells are all fused, physically connected with no gaps.
What is Reticular Theory?
Two processes of charged particles accumulating in the soma over both time and space; can lead to an action potential
What are Temporal and Spatial Summation?
This brain region is critical for learning and memory.
What is the hippocampus?
Railroad worker whose behavior changed after a spike went through his frontal lobe
Who is Phineas Gage?

Who is Brenda Milner?
This type of glial cell is shaped like a star.
What is an astrocyte?
This large, cancerous cell type arises from dysregulated glial cell division
What is glioblastoma?
This mechanisms transports 3 sodium ions out of the cell and 2 potassium ions into the cell.
What is the Sodium-Potassium pump?
These are the bumps and grooves visible on the cerebral cortex
What are the gyri and sulci (or a gyrus and sulcus)?
Who is Hans Berger?
The synaptic vesicles, which store neurotransmitters, are located in this specific region of the neuron.
What is the axon terminal?
This brain region arises from the spinal cord and is responsible for basic vital functions, such as breathing.
