Background Information
☆ What are “Neurons”?
☆ Neuronal Function
What are “Neurons”? A neuron is a nerve cell that is the basic building block of the nervous system. A one-year old human has about 100 billion (1011) neurons. A typical brain neuron will have connections with at least 1,000 other neurons.
Neuronal Function
Thus, in a depolarization, the sodium ions will rush into the axon faster than the potassium ions will rush out. This sudden depolarization (called an action potential) will briefly result in a +30 millivolt potential difference. Once the slowly-opening voltage-gated potassium ionchannels have opened and allowed potassium to flow out, the action potential is ended. Thus, the sodium ion-channels initiate the action potential, and the potassium ion-channels terminate it. The channels then close, and the sodium pump can restore the resting potential of -70 millivolts. But the action potential will propagate down the axon toward the synapse like a line of falling dominos.
Words and Expressions
exacerbate: vt. make (a problem, bad situation, or negative feeling) worse
Examples ★ This attack will exacerbate the already tense relations between the two communities.

Words and Expressions
hype: n. extravagant or intensive publicity or proms”?
What are “Neurons”?
The brain is a vastly complicated signaling system, with neurons forming the basis of that system. Electrochemical signals flow in one direction only in neurons, originating at the dendrites or cell body (usually in response to stimulation from other neurons) and propagating along axon branches which terminate on the dendrites or cell bodies of perhaps thousands of other neurons. The connections between the ends of axons and the dendrites or cell bodies of other neurons are specialized structures called synapses.
★ The effects of the drought have been exacerbated by a history of agricultural problems.
Words and Expressions
endeavour: vi. try hard to do or achieve something
Examples
★ People went to see the movie because of all the hype.
★ I don’t believe all the hype about how good the French team will be this season.
Words and Expressions
espouse: vt. adopt or support (a cause, belief, or way of life)
Examples
★ The left has espoused the causes of sexual and racial equality.
Words and Expressions
Neuronal Function
The basis of neuronal electrochemical signals lies in the neuron membrane. Like all cell membranes, the neuron membrane is a phospholipid bilayer. In other words, the membrane is a “fat sandwich”, with fatty acids between two slices of polar (phosphate) “bread”. The membrane is pierced with proteins that serve as channels for ions to “flow” though (like straws stuck in a sandwich).
Words and Expressions
propensity: n. an inclination or natural tendency to behave in a particular way
Example ★ She's inherited from her father a propensity to talk too much. ★ He's well-known for his natural propensity for indiscretion.
escalation: n. rapid increase
Example
★ The reorganization has led to a dramatic escalation in costs.
★ It's difficult to explain the recent escalation in/of violent crime.
