Equations
The rate of conduction of current is proportional to this.
What is lambda (length constant) over tau (time constant).
The 4 types of glial cells in vertebrate brains.
What are astrocytes, microglia, ependymal cells, and oligodendrocytes.
The number of genes needed to encode 1 Na+ channel vs 1 K+ channel
What is 1 gene for 1 Na+ channel and 4 genes for 1 K+ channel
What is a voltage clamp
This region has maintained its primitive organization in 3 layers throughout vertebrates.
What is the hippocampus
The equation for electrical work
What is zFV? (valence x Faraday's constant x Voltage)
What is ependymal cell
This ensures that only the ion of interest will flow through the channel
What is a selectivity filter
The method used when one wants to investigate the amount of current flowing through individual channels. Performed by using glass pipette to become continuous with the cell cytoplasm.
What is the patch clamp method
Over evolution, this region of the brain has consistently grown larger and folded.
What is the cerebellum
The equation for chemical work
RT*ln([Xin]/[Xout])
This subtype of ependymal cells helps to monitor brain glucose levels and projects to the hypothalamus.
What is tanycyte.
Apamin blocks this channel
What is SK channel (KCa2)
This imaging technique has poor spatial resolution, but can penetrate through the skull.
What is fMRI
What is the allocortex
The value for 2.303 RT/F for a monovalent ion at 18 C
What is 0.058 V (or 58 mV)
This type of cell removes excess GABA and glutamate from synapses, BUT is also a precursor for GABA and glutamate production.
What is astrocyte.
This type of voltage-gated calcium channel is fast to open and slow to close
What is Cav2 (or P-type, R-type, or N-type)
This type of light, when shone on the brain, changes its reflectance with the amount of total blood flow in the brain.
What is green light
The word that means the cerebrum is folded
What is gyrencephalic
What Vinfinity stands for in this equation: Vt = Vinfinity (1-e^-t/T)
What is the voltage across the capacitor when the neuron has reached its steady state.
The way that astrocytes help to regulate blood flow in the brain.
What is responding to glutamate released by activated neurons and then releasing signaling calcium to vasodilate or vasoconstrict arterioles
Dendrotoxin blocks these channels
K+ channels
This reflectance is strongly influenced by the ratio of oxygenated to deoxygenated blood.
What is red light
The most cell-dense part of the brain
What is the granule layer of the cerebellum
