The brain is divided into different lobes, namely the Frontal, Parietal, Occipital, and Temporal lobes, each having specialized functions (Kumar & Bhuvaneswari, 2012). The frontal lobe has the control of memory, thinking ability, decision making, reasoning, impulse control, emotions, and speaking quality. In case this part gets injured, it may affect memory, emotions, and language. The Parietal Lobe is concerned with sensory information coming from different parts of the body. If there happens some damage to this part, the inability problem for recognizing and locating body parts may occur. The Occipital Lobe processes visual information and causes color blindness after getting an injury. The last one, Temporal Lobe, is responsible for sound and speech, precisely for hearing, recognizing language, and forming memories. It may create hearing loss and the problem of identifying languages after injury.

Road-crossing is a dynamic activity, which requires synchronized actions of pedestrians in facing different traffic scenes, such as visual perception and discrimination of coming vehicles, cortical flexibility and executive function to judge and decide the crossing time, and activation of the relevant motor controls to cross the road. Previous studies have shown that old age is the major risk factor of unsafe crossing road for pedestrians [7]. However, the information regarding the role of cognitive functions in crossing road in this aged population is scarce. In our study, we found that visual-spatial dysfunction (CFT-copy and CFT-recall) and decreased executive flexibility (TMT B-A) have an impact on the correct decision making in crossing road behaviors in both PD and control groups. In line with the information procession demands of the crossing road, measures of visual-constructional abilities (CFT-copy), visual perception (VFD), visual memory (CFT-recall), and executive function (TMT B-A) correlated significantly with the outcome of safe crossing road. In our studied subjects, the mean age of enrollment is 66.81 years. As age-related cognitive decline is not uniform across cognitive domains, previous studies have suggested “frontal aging hypothesis” that cognitive abilities mediated by the frontal lobe are highly vulnerable to the aging effects [26]. Therefore, in support of our findings, the age related frontal executive dysfunction partially contributed to poor crossing road behaviors in our study populations.

The majority of our understanding of the functioning of the cortex and the task assignment to various regions comes from knock out studies and observing subjects with mental deformities and diseases (Dikmen, Machamer, and Temkin 2017). Take for instance the frontal cortex, which given its size and location is the most vulnerable to injury. An injury to the frontal lobe can cause drastic behavioral and personality changes in the patient, as well as it can permanently completely impair the fine-tuning of motor skills and may cause a loss of function in the limbs (Kraus et al. 2007).

The signals were recorded through all 24 EEG channels of the EasyCap. The analyses were primarily based on the frontal, temporal and occipital region channels (Fp1, Fp2, F3, F4, F7, F8, T7, T8, O1, O2). The channels on the cap and the related brain regions are shown in mutually identical colors in Figure 5. The central electrodes in orange are in the region between the frontal and parietal. The functions of the frontal lobe involve decision-making, controlling emotions and problem-solving. The temporal lobe is important for hearing, long-term memory and speech. The occipital lobe mainly serves on visual perception. Since the diffusion task involves decision-making and memory processes and visual stimuli, the channels in these brain regions were taken into account.

The frontal lobes play a role in many processes, such as motivation, intention, attention, and concentration. The temporal lobes include regions concerned with memory, visual, and auditory processing. The parietal lobes are associated with perceptual and cognitive integration, memory, and selective attention. The occipital lobes are associated with visual processing.
