PS262 Chapter Notes - Chapter 3, 6, 11: Sine Wave, Sound, Binding Problem
Document Summary
As signals travel from neuron to neuron the representation/ info is getting transformed/ changed/ processed and interpreted. * y(cid:374)apse a(cid:396)e used (cid:271)y the (cid:374)e(cid:396)(cid:448)ous syste(cid:373) to (cid:862)p(cid:396)o(cid:272)ess(cid:863) ele(cid:272)t(cid:396)i(cid:272)al sig(cid:374)als as they travel from the receptors to the brain (the info is actually changed by the neural circuits) * *perceiving the 2 squares that appear in different contexts (on different backgrounds), as being different, even though they are physically identical, is called (cid:862)si(cid:373)ulta(cid:374)eous (cid:272)o(cid:374)trast * *researchers can measure the results of convergence and inhibition in the retina: they can record from a ganglion cell fiber, determine how it respond to the stimulation of receptors by images presented to the eyes * A change in activation could be either an increase caused by excitation, or an decrease caused by inhibition. *receptive field (rf) of the neuron: the region of the retina that, when stimulated, influences the firing rate of the neuron *
