You discover a new species of poison-dart frog which secretes a neurotoxin in the skin mucous with LD50 of 0.5 mg/kg in humans. The toxin causes numbness, paralysis, arrhythmias, cardiac failure, and death. Based on the patch-clamp record of inward currents when the neurotoxin was applied to squid axon shown in Figure 2, suggest the mechanism of action of the neurotoxin. 500 PA 5 ms Figure 2 (Source: Google image)

Defense Mechanism

Circumstances influence and compel people to behave in a certain way. One such behavior is a defense mechanism. It is employed by people to escape from unpleasant circumstances, thoughts and actions. Defense mechanisms are, thus, psychological strategies that help to avert and avoid unwanted feelings such as guilt or shame and situations such as threat and danger.
