with health professionals focusing mainly on the mother and baby. Although it is important for
women to receive this additional support, this focus on motherhood neglects the important role of
fathers. This paper describes two studies on the transition to parenthood and the impact of
supporting the couple relationship.

Brain-behavior correlates of perception and learning in the primate & human brain.

4010.1 Improved neuronal localization during brain activation, A. Song, Duke University,
Durham, NC, USA
We hypothesize that significant capillary fMRI signals, which are closely tied to the neuronal
activities, can be detected by specialized MR acquisition methods without susceptibility artifacts
at high magnetic fields (e.g. 4T). To test this hypothesis, we have developed robust imaging
sequences to achieve uniform spatial coverage free of susceptibility-induced signal losses, we
have also developed contrast mechanisms based on apparent diffusion coefficient (ADC) changes
from the intra-voxel incoherent motions (IVIM) to improve the spatial accuracy of activity
localization. Preliminary validation on the improved localization has been carried out using
diffusion tensor imaging (DTI) based fiber tracking algorithms.
4010.2 Mechanism of selective attention: Single cell, lesion and fMRI data, P. de Weerd,
University of Maastricht, Maastricht, The Netherlands
We typically learn only about sensory input that is important to us. Such information is selected by
attention for further processing, and may be turned into some type of memory. This resentation
focuses on the physiological mechanisms that underlie our ability to selectively attend to relevant
information. Single-cell recordings obtained in Macaques while receptive field stimuli were
attended will be compared with recordings obtained with the same stimuli, but in the absence of
attention. The implications of these findings will be discussed with respect to human fMRI studies
and lesion studies in Macaque monkeys.
4010.3 Selective attention to object features: Linking perception to action in area V4, G. Bertini,
University of Verona, Verona, Italy
Visual selective attention has been shown to modulate activity in the primate extrastriate cortex in
a variety of behavioral contexts. We investigated whether the responses of area V4 neurons can be
modulated by selectively attending to only one of the target stimulus' component features. While
neurons were often gated by feature-selective attention, the surprising result was that during the
trial, the activity of many neurons evolved to encode which of two alternative behavioral
responses was required by the relevant stimulus feature, suggesting that V4 plays a role at the
level of decision processing, i.e. in linking perception to action.

human perceptual, cognitive and motor learning, A. Karni, Haifa University, Haifa, Israel
