Slow-oscillatory tACS does not modulate human motor cortical response to repeated plasticity paradigms.

Previous history of activity and learning modulates synaptic plasticity and can lead to saturation of synaptic connections. According to the synaptic homeostasis hypothesis, neural oscillations during slow-wave sleep play an important role in restoring plasticity within a functional range. However, it is not known whether slow-wave oscillations-without the concomitant requirement of sleep-play a causal role in human synaptic homeostasis.

A psychometric evaluation of the Female Sexual Function Index in women treated for breast cancer.

Background: We aimed to determine the psychometric properties and factor structure of the 19-item Female Sexual Function Index (FSFI) in 132 sexually active women previously treated for breast cancer.

Methods: Confirmatory factor analysis explored three models: (a) second-order six-factor, (b) six-factor, and (c) five-factor models combining the desire and arousal subscales.

Results: Results revealed excellent reliability for the total score (Cronbach's α = 0.
