An Honors program is available to outstanding students with a minimum GPA of 3.5 who are pursuing a B.A. or B.S. in Neuroscience. This program offers students exceptional opportunities to participate in scientific research, culminating in the experience of writing an Honors thesis summarizing their completed research. Honors students are required to gain research in a lab; they register for 4 units of Directed Research (NEUR 490) as one of their UDEs (Upper Division Electives). During their junior and senior years, Honors students also take two semesters of an Honors Seminar (NEUR 493, 1 unit/semester), in which small groups of students discuss recent experimental findings in Neuroscience and their own research. After completing the Honors Seminar, senior Honors students also take one semester of Honors Thesis (NEUR 494, 2 units), in which they write their Honors Thesis.
