100
This is the integrator of information in neurons.
What is the soma?
100
The breaks in between myelin are called this.
What is Node of Ranvier?
100
This mode of active transport moves 3 Na+ and 2 K+.
What is the sodium potassium pump?
100
This disease is a myelin degenerating disorder.
What is multiple sclerosis?
100
Multiple samples of the same condition from different donors are called this.
What is a biological replicate?
200
This part of the neuron sends information at the synapse.
What is the axon terminal?
200
This is used to calculate the membrane potential of a neuron.
What is the Goldman equation?
200
There are high concentrations for potassium in this part of the neuron.
What is intracellular?
200
Long and thin dendritic spines characterize this condition.
What is intellectual disability.
200
This type of image manipulation is considered acceptable.
What is adjusting overall contrast?
300
This type of staining highlights the cell bodies of neurons.
What is Nissl staining?
300
Action potentials travel down the myelinated axon via this method travel.
What is saltatory conduction?
300
In some cells, this causes depolarization instead of sodium.
What is calcium?
300
This is a disorder characterized by abnormal protein accumulation involving the cytoskeleton.
What is Alzheimer's disease?
300
This type of research is robust, reproducible, and is open-ended.
What is discovery-based research?
400
Microglia functions as this in response to damage.
What are macrophages?
400
These are the two types of AP firing.
What is burst and regular firing?
400
This type of channel opens slowly in response to depolarization.
What are voltage-gated potassium channels?
400
Lack of closure in the anterior end of the neural tube is called this.
What is anencephaly?
400
This separates the temporal lobe from the frontal lobe.
What is lateral sulcus?
500
This type of cell buffers extracellular K+ concentrations.
What are astrocytes?
500
This plays an integral role in regulating the homeostasis of external potassium.
What is the BBB?
500
The S4 helix of the voltage-gated sodium channels have positively-charged resides of these amino acids.
What is lysine or arginine?
500
Ingestion of this blocks sodium channels.
What is TTX or lidocaine?
500
This structure of the brain connects the left and right hemisphere.
What is corpus callosum?
