Effect of movie clips on human brain

Abstract

In this paper, we investigated the changes in brain activation with respect to watching movie clips in order to understand its effect on human brain. Electroencephalography (EEG) data was recorded using 24-channel EEG machine while subjects watched the movie clips. 14 male subjects were recruited for this research project. Two conditions were used in collecting EEG data; i) under eyes open condition while subjects looking at a white screen for five minutes and ii) while subjects watched selected movie clips for 20 minutes. Hence, the eyes open condition at resting state was considered as baseline and the brain activation signal due to movie clips was compared with the baseline for analysis. After data acquisition, data were cleaned to remove artifacts like eye blinking, eye movement and drowsiness. Three features were used in this research to analyze the EEG data, i.e., absolute power, coherence and phase lag. Each of the features was analyzed in four frequency bands, i.e., delta, theta, alpha and beta. It was found that the absolute power for beta and alpha bands was higher in occipital, parietal, frontal and motor regions while watching movie clips as compared to baseline. Beta band was associated with learning and making responses. The frontal and the central brain lobes were highly coherent in beta and alpha bands indicating connectivity between the frontal and central regions. Faster communication between the occipital, parietal, frontal and motor areas was also observed in the phase lag analysis.

The Power of Fear: Exploring the Neural Responses to Horror Scenes in Different Audiovisual Modes

“…In addition to ISC, researchers focus on depicting detailed patterns of cerebral activity with video or movie situations, for example, scanning deep areas in the brain [16,24], finding the connection between regions [29], and testing and comparing differences between viewers' brain responses and their subjective experience. In recent years, the brain-controlled films emerged, which enables the audience to engage with the content they are viewing [39,40,43], and the resulting movie no longer has a single directional feeding.…”

Central Nervous System Responses to Comfortable Thermal Stimuli to the Soles of the Feet with Simultaneous Presentation of Other Sensory Stimuli

“…Previous studies evaluated other stimuli (music, movie, illumination, vibration and odor) based on physiological responses of the central nervous system [9][10][11][12][13][14][15][16][17][18][19][20][21]. First, listening to relaxing music has been found to increase power spectrum components of the α-wave [9] and θ-wave [10] of the EEG signal and to decrease cerebral blood flow in the frontal lobe [11].…”

“…First, listening to relaxing music has been found to increase power spectrum components of the α-wave [9] and θ-wave [10] of the EEG signal and to decrease cerebral blood flow in the frontal lobe [11]. Second, in a study of movie and image presentation, Aamir et al [12] reported that watching movie clip increased absolute α-wave power in occipital, parietal, frontal and motor regions compared to baseline. Additionally, Sakamoto et al revealed cerebral blood flow in the frontal lobe is an indicator of video comfort or discomfort [13].…”

“…Music stimuli, movie stimuli, illumination stimuli, odor stimuli and vibration stimuli (applied to the trunk) were presented. Previous studies evaluated participants' brain activity when presenting stimuli to a single sensory modality, based on physiological responses of the central nervous system [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21]. However, few studies have examined the combination thermal stimuli with stimulation of other sensory modalities.…”
