The benefits of insoles, commonly used to improve the walking gait, have been little studied. Therefore, the aim of this study was to assess the walking gait variability and stability on different walking conditions (without shoes, WTS, with shoes, WS, with shoes and insoles, WSI) related to brain activity. Twelve participants randomly (WTS/WS/WSI) walked on a treadmill at 4 km/h for 10 min. Kinematic analysis (i.e., footstep and gait variability), brain activation (beta wave signal), rating of perceived exertion (RPE, CR-10 scale), and time domain measures of walking variability were assessed. The maximum Lyapunov exponent (LyE) on the stride cycle period’s datasets was also calculated. Stride length and cycle calculated for all walking conditions were 61.59 ± 2.53/63.38 ± 1.43/64.09 ± 2.40 cm and 1.11 ± 0.03/1.14 ± 0.03/1.15 ± 0.04 s (F1,10 = 4.941/p = 0.01, F1,10 = 4.93...

We used pictures from Ekman and Friesen in an event-related potentials study to investigate the neurophysiological correlates of the fear emotional processing compared with happiness in patients with schizophrenia versus healthy subjects. A significant lower P300 amplitude for fear processing but not for P100, N170 and N250 amplitude was found in schizophrenics compared to controls. These data suggest that the ability of basic visual processing is preserved in schizophrenia, whereas facial affect processing is impaired.

The aim of the present study was to verify the effects of estrogens in the interplay of cognition and emotion. Images from the International Affective Pictures System, based on valence (pleasant, unpleasant and neutral), maintaining arousal constant, were viewed passively by two groups of young women in different cycle phases: a periovulatory group (PO), characterized by high level of estrogens and low level of progesterone, and an early follicular group (EF), characterized by low levels of both estrogens and progesterone. The electrophysiological responses to images were measured, and P300 peak was considered. One week later, long-term memory was tested by means of free recall. Intra-group analysis displayed that PO woman had significantly better memory for positive images, while EF women showed significantly better memory for negative images. The comparison between groups revealed that women in the PO phase had better memory performance for positive pictures than women in the EF phase, while no significant differences were found for negative and neutral pictures. According to the free recall results, the subjects in the PO group showed greater P300 amplitude, and shorter latency, for pleasant images compared with women in the EF group. Our results showed that the physiological hormonal fluctuation of estrogens during the menstrual cycle can influence memory, at the time of encoding, during the processing of emotional information.

In this paper we used, in an Italian sample, an adaptation of a paradigm previously utilized in American samples to study the relationship between emotion and long-term memory. Seventy-two healthy adults from different educational backgrounds were randomly assigned either to a neutral group or to an emotional arousal group and then told a short story, presented audio-visually. In both groups, the slides shown and the slide sequence were the same, and the images were accompanied by a narrative. The two versions of the story differed primarily in their emotional content. Shortly after viewing the slide presentation, the participants were asked to rate the emotionality of the narrative, and ten days later were submitted to a retention test. The emotionally-arousing version of the story was rated as more emotional than the neutral one. Compared with the members of the neutral gr...

We report two studies evaluating the ef fects of emotional content on declarative memory, conducted with healthy subjects and cephalgic patients. We utilized an adaptation of two versions of the same story, with different arousing properties (neutral or emotional), which have been already employed in experiments involving the enhancing effects

Also, an effect of sex on brain activation during the recognition of fearful faces, despite no sex differences in task performance was reported (Kempton et al., 2009). Sex differences in cognition are consistently reported: for example, men excel in mental rotation and spatial perception while women perform better in verbal memory tasks, verbal fluency tasks, speed of articulation, episodic memory tasks, and in the utilization of prosodic information (Schirmer et al., 2002; Schirmer and Kotz, 2003). Furthermore, language and reading disorders are reported to occur approximately twice as often in boys than in girls (Flannery et al., 2000), reflecting the sex-related difference in cognitive skills. Sex-related differences in language processing are well known from everyday life, as well as from scientific literature (Hill et al., 2006; Catani et al., 2007). Why females generally perform better on language tasks than males is still unknown (Burman et al., 2008). A common hypothesis attributes this differences to a bilateral contribution of languagerelated cerebral areas in females and a left-hemispheric dominated activation in males (

The present review summarizes research conducted in our laboratory and others with the aim of identifying the role of estrogen on cognitive functions. In the first section, we briefly describe the neurobiology of estrogen; in the second, we discuss the effects of estrogens on cognitive behaviors in mammals, as well as the physiological relevance of these effects and their applicability to human health and disease. The third section details the role of estrogens on working memory in humans and non human primates, and in rodents, and the concluding section briefly describes the relations between estrogens and the aging brain.
