Answer:
This is synaptic pruning- it removes them
Explanation:
The gaps and the portions of neurons between adjacent neurons is called synapse.It role is to moderate synaptic connections among neurons.
As organisms (man and other higher animals)develop from birth to adult,new synaptic connections are formed,and old ones are removed.The process whereby the the axon and dendrite, as part of the synapse, decay and removed by the brain is called synaptic pruning or pruning process.
This process begins at childhood and continue till maturity- at mid twenties.it occurs during sleep.
it helps to improve learning and memory,because new connections are made to replace the old ones,and therefore smooth transition of the brain from childhood to adulthood
Three models have been used to explain pruning-Axon degeneration,retraction and Axon shedding.
Answer:
Hallucinogens
Explanation:
Hallucinogens are a group of drugs, mostly of plant origin, that completely modify the ability of ideation. There are modifications of the course of thought. They are the most potent drugs, because they are used in the amount of micrograms (thousandth of the milligram).
The person using hallucinogen has changes in the course of thought. The individual is relatively consciously aware of the almost automatic unfolding of his thinking: the associations of ideas are freely, capriciously, sometimes absurd. In addition, the individual has increased heart rate, higher blood pressure and dilated pupils.
The principle of sequence involves appending more effort at every exercise to reinforce the muscles. You simply endeavor to perform more than you did the previous time
The answer is body's line of defense. The first line of defense which includes physical as well as chemical barriers would defend the body from infection. It would include the tears, cilia, stomach acid,urine, white blood cells,mucus and the skin. The skin is the largest organ and would act as a barrier from pathogens. If first line of defense won't work the second line will then be activated.
