<span>The population of the Northern states was more than twice that of the Southern states. Despite the fact that many people, in both the Northern and Southern states, worked on farms during the time before the Civil War, the Northern become both more industrialized and more urbanized, while plantation agriculture remained the focus in the South. The industrial transformation which took place in the North caused the two territories’ economies to develop very differently. Transportation improved via railroad development and manufacturing exploded in the North, making it attractive to opportunity seekers looking for improved wages in the North and West states. The cities in the areas offering manufacturing jobs experienced major population growth which triggered extensive housing and urban development, and provided an economic environment conducive to the establishment of a middle-class made up of skilled and white-collar workers.</span>
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.
