Historical Origins
Although the task of cognitive neuroscience is to describe how the brain creates the mind, historically it has progressed by investigating how a certain area of the brain supports a given mental faculty. In other words, for most of its history, the biggest question of cognitive neuroscience was "Where?" We could begin with Aristotle, who argued that sensory information went from the senses to the heart, which he thought was the seat of reason. Later observers correctly identified the brain as the biological substrate for thinking. However, early efforts to subdivide the brain proved problematic. The phrenologist movement failed to supply a scientific basis for their theories and has since been rejected. However, the phrenological assumption that specific areas of the brain conduct specific functions still applies. The modern evidence for this specificity (sometimes called modularity) includes direct recording from single neurons, case studies of patients with brain damage or disease, recording of electrical or magnetic activity in the brain through advanced scanning techniques, and even direct manipulation of brain activity.

Famous quotes containing the words historical and/or origins:
“Some minds are as little logical or argumentative as nature; they can offer no reason or “guess,” but they exhibit the solemn and incontrovertible fact. If a historical question arises, they cause the tombs to be opened. Their silent and practical logic convinces the reason and the understanding at the same time. Of such sort is always the only pertinent question and the only satisfactory reply.”
—Henry David Thoreau (1817–1862)
“Grown onto every inch of plate, except
Where the hinges let it move, were living things,
Barnacles, mussels, water weeds—and one
Blue bit of polished glass, glued there by time:
The origins of art.”
—Howard Moss (b. 1922)
