Explanation:
There are seven challenges for neuroscience:
BY THE DEFINITION/FROM A SOURCE:
Challenge 1. Change the way neuroscience is done.
Challenge 2. Data ladders.
Challenge 3. Predictive neuroscience.
Challenge 4. Simulating the brain.
Challenge 5. Classifying and simulating diseases of the brain.
Challenge 6. From the brain to brain-inspired technology.
Challenge 7. Working with society
Those are the challenges they have, and they each represent a different problem.
Brain lesions:
Nausea, vomiting, personality changes, headaches...
Answer: a. too much acetylcholine staying in the neuromuscular junction for too long
Explanation:
Sarin is a gaseous organophosphate. This gas is used for chemical warfare. This affects the nervous system of the body. The gas if inhaled can cause death within minutes.
Acetylcholine is a neurotransmitter molecule. It is released from the pre-synaptic neurons that binds to the acetylcholine receptors.
The gas sarin will target the enzyme acetylcholinesterase present in the neuromuscular junction of the body where the nerves actually meet the muscles. The enzyme degrades nerve signaling molecule acetylcholine. Thus when the sarin degrades the enzyme the levels of acetylcholine will rise up in the blood. The acetylcholine remain in the neuromuscular junction. The acetylcholine will stimulate the nerve cell receptors. Excess of acetylcholine will cause excessive twitching and may lead to paralysis.
Answer:
2ml
Explanation:
There are 25mg in every ml;
The patient requires 50mg;
We can use ratios:
1 : 25
x : 50
x/1 = 50/25
x = 2
