| Furthermore, in the slice preparation, the influence of the blood brain barrier is removed. The ability to change the tissue concentration of interesting molecules at will provides good experimental control of the preparation. In addition to the temperature and oxygen concentration, the pH, ionic concentration and hormonal levels can be changed at will. The slice neurons are consequently under less synaptic bombardment than cells in the intact brain. Other modulating influences (neuromodulators, biological clocks, hormones) are also absent. | Furthermore, in the slice preparation the influence of the blood brain barrier is removed.

| Hebb (1949) increased our understanding of how networks of neurons might store information with the provocative theory that memories are represented by reverberating assemblies of neurons. Hebb recognized that a memory so represented cannot reverberate forever and that some alteration in the network must occur to provide integrity both to make the assembly a permanent trace and to make it more likely that the trace could be reconstructed as a remembrance. Neurons communicate with each other only at synapses, the activity of the assembly or network is most easily altered by changes in synaptic function. | Hebb (Hebb, 1949) increased our understanding of how networks of neurons might store information with the provocative theory, that memories are represented by reverberating assemblies of neurons. Hebb recognized that a memory, so represented cannot reverberate forever and that some alteration in the network must occur, to provide integrity both to make the assembly a permanent trace and to make it more likely that, the trace could be reconstructed as a remembrance. Because neurons communicate with each other mainly through synapses, the activity of the assembly or network is most easily (perhaps only) altered by changes in synaptic function.
