The magnetic equivalent of the contingent negative variation (CMV) and visual evoked magnetic fields (VEF) in anticipation of pictures of opposite-sex nude, same-sex nude, and neutral photographs has been recorded with whole-head MEG in 12 males and 12 females. Subjective ratings of valence indicated a strong gender effect. While females rated both male and female nudes as neutral, males rated male nudes similar to neutrals but female nudes received higher scores of pleasantness. Gender differences were also found for ratings of picture-induced arousal. While females rated male and female nudes as equally arousing, males attributed more arousal to opposite-sex nudes. The CMV instead revealed, for both male and female participants, higher amplitudes for opposite-sex nudes. VEF in response to nudes revealed two components with mean latencies of 126 and 203 ms. The amplitude of the first component was stronger in males than in females, and only in males the magnetic activity was increased in response to male and female nudes compared to neutral pictures. For the second component the mean magnetic activity was higher in response to nudes than to neutral contents for both male and female participants. The results are discussed in terms of an evolutionary view of sexual selection, which predicts a greater response in male subjects to stimuli relevant for mate choice.
We investigate the effect of strain on the
Opto-electronic properties of Si-NCs pairs. We consider two sources of strain:
The strain induced by an embedding SiO2 matrix, and the strain generated by
Mutual NC-NC forces occurring at small distances. Independently on its source,
We observe a fundamenta...
We present an overview of a fully covariant formulation for describing the
Production of strangeness -1 and -2 hypernuclei using probes of different
Kinds. This theory is based on an effective Lagrangian picture and it focuses
On production amplitudes that are described via creation, propagation and...
We address the issue of the validity of linear response theory for a closed
Quantum system subject to a periodic external driving. Linear response theory
(LRT) predicts energy absorption at frequencies of the external driving where
The imaginary part of the appropriate response function is different...
