Shortly before their first babies were born, men’s hormone levels, their emotional responses to
infant stimuli, and whether they had experienced physical changes throughout their partners’
pregnancies were recorded. The men were later tested after interacting with their two-week,
two-month and 20-month old children. Men with high prenatal responsiveness (reporting feeling
concerned after hearing taped baby cries or reporting numerous couvade or male pregnancy
symptoms) showed a different hormonal pattern after father-child interactions than less responsive
men. These results suggest that prenatal variation in responsiveness provides an indication of how
men will respond to contact with their own children.

The ability to recognize other individuals’ emotional states is important to behave socially and
adaptively in primates. Recent data have suggested a number of similarities in facial expressions
or vocalization between humans and nonhuman primates, especially chimpanzees. However, in
nonhuman primates, only a few experimental studies have investigated the effects of emotional
expressions on the recipients. The present study examined chimpanzees’ and humans’ responses to
unfamiliar chimpanzees’ emotional stimuli: facial portraits and voices in 4 categories from scenes
of subjects 1) screaming, 2) being excited (vocalizing pant-hoot), 3) playing, and 4) begging for
food and vocalizing food-grunt.
2028.82 Stress-protective effect of glucose on behaviour, Kathrine P. Vinogradova 1 , Dmitry

The search of safety stress protective drugs is an important problem. Anxiety levels in rats were
determined before and after exposition to mild stress. The glucose was injected just immediately
after stress. In control stress induce significant individual changes of behaviour, which may be
caused by various influence of stress on person with different coping style. Rats after glucose
injection showed slight individual changes in anxiety and locomotion. The present data suggest
the stress-protective effect of glucose being injected after aversive event.
2028.83 Genetic-environmental animal model of depression and anxiety, Dmitry Zhukov 1 ,
Kathrine P. Vinogradova 2 , 1 Pavlov Institute of Physiology, Russian Federation, 2 St.-Petersburg
State University, Russian Federation
Proposed models are two rat strains genetically selected for high (KHA) and low (KLA)
acquisition of active avoidance subjected for escapable or inescapable footshocks. Inescapable
footshocks applied to KHA rats induce escape failures and dexamethasone nonsuppression of the
BHPA axis. In contrast, KLA rats exposed to footshocks demonstrate elevated anxiety and
elevated corticosterone levels, but the learning abilities, and dexamethasone-reactivity of KLA rats
still unchanged. Therefore, the KHA rats exposed to inescapable stress represent the model of
depression, and KLA rats exposed to stress represent the model of elevated state anxiety.
