Central to secondary prevention is early identification of drug problems. Secondary prevention includes activities aiming at early detection problem or disease. After this, all necessary activities are undertaken to prevent further spread of disease, social problems or risky behavior. In this case, secondary prevention includes early detection of drug addict or behavior disorders which is caused by using drugs.

Answer:
The Intercoastal Highway in South America is a highway that connects the western and the eastern coast of the continent, running through the countries of Peru and Brazil. The big positive of this highway is that it is connecting the eastern and western part of the continent, enabling for easier transportation of goods, and easier movement of people, which is of great economic benefit for everyone involved. On the other hand, there are also negatives, with the two biggest being the destruction of lot of tropical rainforest, and deaths of animals. In order for this highway to be built, enormous amount of trees and other vegetation have been cut down, which is always a problem.

Neuroscientist have discovered a mechanism that contributes to the strengthening of associations, also called synapses.
<h3>What are synapses?</h3>
A synapse is a physical component of the nervous system that enables a neuron (or nerve cell) to transmit an electrical or chemical signal to an additional neuron or to the intended effector cell.
The transfer of nerve impulses from one neuron to another requires synapses. Synapses are the way by which neurons, which are specialized to convey messages to specific target cells, accomplish this. The plasma membrane of the target (postsynaptic) cell and the plasma membrane of the signal-passing neuron are in close proximity at a synapse. The large arrays of molecular machinery that link the two membranes and carry out the signaling process are present at both the presynaptic and postsynaptic locations. Many synapses have an axon for the presynaptic component and a dendrite or soma for the postsynaptic component. Additionally, astrocytes communicate with synaptic neurons, responding to synaptic activity to control neurotransmission.
