Document Summary
But they could be "over-trained" to follow s-r associative behavior: lidocaine: a local anesthesia applied to the rats caudate or hippocampus after training sessions. Control group has saline solution injected: caudate: injections into the caudate had no effect on test performance (matched control, hippocampus: first week performance was heavily impaired (basically randomly picking which side to go to). Over training has the same effect as the control group (learned response not place) Phrenology: using fmri scans to detect changes in oxygen concentrations in the brain during specific tasks. Sensitization: increase in various responses often unrelated to original stimuli. Like being scared so you become more alert and jumpy. Pavlovian conditioning: pairing us (food) and ur (natural response: salivating) through a cs (alarm) turns form a cr (presence of cs causes cr). Optimal isi is intermediate (~750ms: delay conditioning doesnt require awareness of association, even amnesiacs could learn this way, trace conditioning: present us, short delay, then present cs.
