		+	• Long-term plasticity, encodes stimulus salience, is gated by signals coming from frontal eye fields.
		+
		+	• Selective attention can change firing rates by about 20%
		+
		+	• Recent research (2006) by Conway and Tsao studied macaque monkeys to investigate what factors influence color in the brain. They propose that when added together with previous research, their results suggest that a connected ventral-stream pathway (including at least V1, V2, V4, and a region on the posterior bank of the superior temporal sulcus called PITd) is responsible for determining color.
