Document Summary

First three topics discussed will be on the midterm (feb 2) 48 multiple choice material = lab activities, lecture slide, assigned readings. Visual adaptation: going from a bright environment to a dark environment it will become almost impossible to see until our eyes fully adapt. We also have off centre ganglion cells which do the opposite: inhibitory section of the ganglion is the centre and when the surrounding cells are activated the cell is more likely to fire. Ganglion are activated most when changes in light are detected: auditory receptive field: receptive field is the frequency not a physical location. Hairs along the cochlea detect different vibrations and frequencies: somatosensory receptive field size and acuity varies with location. Lots of receptors within the hand feet and face compared to spaced out rectors found on your back. We can measure receptive field by measuring the distance two stimuli have to be to tell its two distinct stimuli.
