I would like to comment an article that came up just today on the news column of neuronetwork: "smoking's up-side: Nicotine protects the brain from Parkinson's disease".. surely an interesting feature which…"

The toxic effects of alcohol on the fetal brain
The toxic effects of alcohol on the fetal brain were first established in France in 1968 and in the United States in 1973 by David Smith, a West Coast pediatrician. The unraveling of this relationship has followed a traditional history- the problem was first brought to attention when infants born to mothers with high alcohol intakes were noticed to have characteristic features: impaired growth, flat face, long upper lip, and mental retardation. This set of dysmorphic features was termed the…See More
Martin Tik replied to MARCOS FLEURY's discussion Drugs of Abuse and Neuroplasticity in the group NEUROSCIENCE RESEARCH ON DRUG ADDICTION"The mesolimbic pathway is involved in all kinds of learning / rewards.
How does drug addiction differ structural or morphological to other learned behavior?"
MARCOS FLEURY commented on MARCOS FLEURY's blog post The Effects of Drugs on Synaptic Transmission"Antidepressants have various effects on the body, including action at the neuronal synapses of the brain; the two most important of these effects are blockade of the reuptake of neurotransmitters, including NE, 5-HT, and dopamine, and blockade of…"

MARCOS FLEURY posted a blog postThe Effects of Drugs on Synaptic Transmission
According to recent research, the following drugs of abuse studied that may cause effects on synaptic transmission are: Alcohol Alcohol inhibits neurotransmission in two ways. First, it inhibits the excitatory channels on the postsynaptic neuron. Next, it lowers the rate of action potentials from the presynaptic neuron. Caffeine At synapses where adenosine is the primary neurotransmitter, a high postsynaptic firing rate leads to sleepiness. Caffeine inhibits sleepiness by inhibiting…See More
MARCOS FLEURY added a discussion to the group NEUROSCIENCE RESEARCH ON DRUG ADDICTIONDrugs of Abuse and Neuroplasticity
Drugs of Abuse induce plastic changes in the brain that seem to underlie addictive phenomena. These plastic changes can be structural (morphological) or synaptic (biochemical), and most of them take place in the mesolimbic and mesostriatal circuits.
