Answer:
Neurotransmitters are chemical substances whose objective is to produce proper communication between neurons. For this to take place, there must be an adequate amount of dopamine and norepinephrine. In children with attention deficit hyperactivity disorder, the production of these two neurotransmitters is irregular; on the other hand, low levels of serotonin are related to the appearance and maintenance of obsessive-compulsive disorder.
Explanation:
Attention deficit hyperactivity disorder is one of the disorders linked to insufficient production of the neurotransmitters dopamine and norepinephrine. This deficit of dopamine and norepinephrine causes problems in the regulatory circuits of various areas of the brain: the prefrontal cortex, the corpus callosum, and the basal ganglia. It is characterized by a difficulty in maintaining voluntary attention in the face of activities; on the other hand, low levels of serotonin are related to the appearance and maintenance of obsessive-compulsive disorder. Serotonin is a neurotransmitter involved in various cognitive processes: modulation of mood, learning, memory, physiological responses, etc. Low levels of serotonin produce unusual responses, overexciting activation in the orbitofrontal cortex, affecting thought and behavior.

Northern Africa was a place of trees, grasslands, lakes and people. Today, it is the Sahara — a desolate area larger area than Australia.
Lake Yoa, in northeastern Chad, has remained a lake through the millennia and is still a lake today, surrounded by hot desert. Although little rain falls, Lake Yoa’s water is replenished from an underground aquifer.
By analyzing thousands of layers sediment in a core drilled from the bottom of this lake, an international team of scientists has reconstructed the region’s climate as the savanna changed to Sahara.</span>
