Here we describe a protocol for bilateral multielectrode neurophysiological recordings during intracerebral pharmacological manipulations in awake songbirds. This protocol encompasses fitting adult animals with head-posts and recording chambers, and acclimating them to periods of restraint. The adaptation period is followed by bilateral penetrations of multiple electrodes to obtain acute, sensory-driven neurophysiological responses before versus during the application of pharmacological agents of interest. These local manipulations are achieved by simultaneous and restricted drug infusions carried out independently for each hemisphere. We have used this protocol to elucidate how neurotransmitter and neuroendocrine systems shape the auditory and perceptual processing of natural, learned …

Observational Learning In Wild And Captive Dolphins, Deirdre Yeater, Stan A. Kuczaj Ii
Psychology Faculty Publications
Many non-human species imitate the behavior of others, and dolphins seem particularly adept at this form of observational learning. Evidence for observational learning in wild dolphins is rare, given the difficulty of observing individual wild animals in sufficient detail to eliminate other possible explanations of purported imitation. Consequently, much of the evidence supporting observational learning in dolphins has involved animals in captive settings. This research suggests that dolphins have an affinity for mimicry, and that they are more successful at observational learning if they choose to imitate another rather than being asked to do so. These results, combined with those …
