Dopamine is one of the main neurotransmitter in the brain to be affected by drug use? True or false
Step by step
Solved in 2 steps
- How is dopamine involved in drug addiction? 1)drugs change dopamine into another neurotransmitter. 2)drugs cause the reabsorption of dopamine. 3)drugs decrease dopamine levels in the brain. 4)drugs increase the level of dopamine in the brain. Please I need a surely answer and a quicker responseDifferent psychoactive substances can produce different kinds of effects, but in general psychoactive substances affect the brain by: altering the activity of neurotransmitters at the synapse. altering the effectiveness of astrocytes and other glial cells. reducing activity in the cortex and increasing activity in the brainstem. all of these optionsPsychoactive drugs work by, EXCEPT: blocking receptors (antagonists) blocking reuptake (antagonists) blocking enzymatic degradation of neurotransmitters blocking the impulsivity to take drugs
- Nootropic drug use is becoming increasingly popular among students on University campuses around the world. The most common network target(s) of these drug cocktails is (choose correct ending): increasing serotonin signaling activities in the brain increasing GABA signaling in the dopamine pathway increasing norepinephrine and increasing acetylcholine behavioral modification network activities in the brain increasing dopamine behavioral modification network activities in the brainWe talked about drug effects on neurons in sequence. The effect of alcohol is multi-faceted and the following question asks you to apply your knowledge. Imagine two neurons in sequence. The presynaptic neuron is GABAnergic and the postsynaptic neuron is dopaminergic. The effects of alcohol are not fully understood but it does seem to inhibit GABAnergic neurons. How would the release of dopamine from the postsynaptic neuron change in this case? Explain your answer, being sure to make each connection between concepts clear. If alcohol instead inhibited dopaminernergic neurons, in what way might the ion flow change in the dendrites of the postsynaptic neuron of this example?If no one treatment for alcohol or other drug use disorders has been found to be effective for everyone, do the available formal treatments for these disorders have any value?
- Why might nonspecific factors influence psychoactive drug effects more than the effect of an antibiotic?What neurotransmitter(s) does cannabis affect? What kinds of effects does it have on these neurotransmitter systems? Does it have agonist or antagonist effects?Would you please explain the axon's functioning and how neurotransmitters cross the synaptic gap and, as such, how the concept of dopamine reuptake blockage explains cocaine addiction?
