“…This finding is consistent with known functions of the left hemisphere as the main language center for most persons (e.g. Sperry, 1968). Wood, Goff and Day (1971) report that AEPs from the left hemisphere differed when linguistic information was presented, as compared to when nonlinguistic patterns of the same acoustic signal were presented.…”

This research directly assesses older people's neural activation in response to a changing urban environment while walking, as measured by electroencephalography (EEG). The study builds on previous research that shows changes in cortical activity while moving through different urban settings. The current study extends this methodology to explore previously unstudied outcomes in older people aged 65 years or more (n = 95). Participants were recruited to walk one of six scenarios pairing urban busy (a commercial street with traffic), urban quiet (a residential street) and urban green (a public park) spaces in a counterbalanced design, wearing a mobile Emotiv EEG headset to record real-time neural responses to place. Each walk lasted around 15 min and was undertaken at the pace of the participant. We report on the outputs for these responses derived from the Emotiv Affectiv Suite software, which creates emotional parameters ('excitement', 'frustration', 'engagement' and 'meditation') with a real-time value assigned to them. The six walking scenarios were compared using a form of high dimensional correlated component regression (CCR) on difference data, capturing the change between one setting and another. The results showed that levels of 'engagement' were higher in the urban green space compared to those of the urban busy and urban quiet spaces, whereas levels of 'excitement' were higher in the urban busy environment compared with those of the urban green space and quiet urban space. In both cases, this effect is shown regardless of the order of exposure to these different environments. These results suggest that

“…Recent work on patients suffering from lesions of the cerebral cortex has generated new interest into the localization of function and its implications for physiological mechanisms of cognition (Sperry, 1968;Milner, 1967;Geschwind, 1965). Work on normals can extend and elaborate these findings.…”
