“…Outside of the spatial domain, we have also noticed that hippocampal birds show less fear and/or are less distractible than control birds , a finding in line with what has been shown in rats (Kaplan, 1968;Raphelson, Isaacson, & Douglas, 1965;Wickelgren & Isaacson, 1963). In fact, despite nearly two decades of research by ourselves and others Hampton & Shettleworth, 1996), we have encountered only Colombo, N. J. Broadbent, C. S. R. Taylor, & N. Frost, 2001, Brain Research, 919, p. 292-301.…”

The literature on the neural basis of learning and memory is replete with studies using rats and monkey, but hardly any using pigeons. This is odd because so much of what we know about animal behavior comes from studies with pigeons. The unwillingness to use pigeons in neural studies of learning and memory probably stems from two factors, one that the avian brain is seen as radically different from the mammalian brain and as such can contribute little to its understanding, and the other that the behavior of pigeons is not seen as sophisticated as that of mammals, and certainly primates. Studies over the past few decades detailing the remarkable cognitive abilities of pigeons, as well as a newly revised nomenclature for the avian brain, should spark a renewed interest in using pigeons as models to understand the neural basis of learning and memory. Here we review studies on the pigeon's hippocampus and 'prefrontal cortex' and show that they provide information not only on the workings of the avian brain, but also shed light on the operation of the mammalian brain.

“…In this respect; Teitelbaum & Milner (1963) have reported that sudden noises, such as hand clapping, greatly increased the frequency with which rats with hippocampal lesions jumped off a platform onto an electrified grid. Similarly, Raphelson, Isaacson, & Douglas (1965) have reported that the introduction of a new visual stimulus into a runway increased the running speed of rats with extensive hippocampal damage. On the other hand; they found that operated and unoperated control ~s typically reduced their speeds when the novel stimulus was first introduced.…”

“…However, both acquisi·tion deficits (Kaada et al~ 19611 Kimble, 1963;Kveim et al t Wickelgren & Isaacson (1963) and Raphelson et al (1965) have found that under certain conditions hippocampectomized rats react less to the introduction of a novel stimulus. It would therefore be valuable te determine more precisely the circumstances in which rats with hippocampal damage do or do not react to novel stimulation.…”

Data suggest that abnormal perseveration of well-established habits during extinction by Ss with hippocampal damage cannot be generalized to learned behaviors such as those consisting mainly of a "stop" component (e.g., conditioned freezing). However, consistent with previous reports of perseveration based on "go-type" responses, the present results also show that once engaged in overt goal-directed activity, rats with hippocampal damage are less affected by extraneous visual stimulation and also habituate slowly.

“…It has been reported that tactile and visual stimulation disrupt the performance of hippocampally damaged rats engaged in a straight runway task less than that of normal animals or animals with only neocortical destruction (Raphelson, Isaacson, & Douglas, 1965;Wickelgren & Isaacson, 1963). In view of these results, the effects of bilateral hippocampal destruction have been interpreted as deficiencies in reactivity while engaged in the performance of behavioral tasks (Raphelson et ai, 1965).…”
