DATES

TOPICS AND ASSIGNMENTS

Jan 29-31

INTRODUCTION: SIGNALS USED BY NEURONS
Signaling the physical world. How neurons convey signals. Visualizing brains and neurons.

Reading: Wolfe et al, Sensation and Perception, 5th edition, 2018 ("Wolfe"), chapter 1, emphasizing pages 19-33 and skipping 17-19 (Fourier analysis, which we will tackle later). Also explore the 3D brain model at www.brainfacts.org/3D-Brain.

Textbook information, course requirements, and other Administrative Information are posted online. The textbook has a companion website at: oup.com/us/wolfe5e.

The first weekly quiz will be on Monday, February 5, at the start of class, on topics from this first reading assignment.
