Projections
The majority of thalamocortical fibers project to layer IV of the cortex, wherein sensory information is directed to other layers where they ether terminate or connect with axons collaterally depending on type of projection and type of initial activation . Activation of the thalamocortical neurons relies heavily on the direct and indirect effects of Glutamate, which causes EPSP’s at terminal branches in the primary sensory cortices.

Famous quotes containing the word projections:
“Predictions of the future are never anything but projections of present automatic processes and procedures, that is, of occurrences that are likely to come to pass if men do not act and if nothing unexpected happens; every action, for better or worse, and every accident necessarily destroys the whole pattern in whose frame the prediction moves and where it finds its evidence.”
—Hannah Arendt (1906–1975)
“Western man represents himself, on the political or psychological stage, in a spectacular world-theater. Our personality is innately cinematic, light-charged projections flickering on the screen of Western consciousness.”
—Camille Paglia (b. 1947)
