Abstract— This paper presents a detailed analysis on EEG signals to classify the different moods in human beings based on EEG signals acquired from biosensors. The main objective of this paper is to understand the procedure used to detect different moods in human beings using the EEG signals associated with each emotion. And to explain how EEG signals are classified.
Keywords— EEG signals, Human emotions(moods).

Emotion plays an important role in human life. Human beings are subjected to various emotions throughout their …show more content…

Because it should be noted that the face expression and speech can intentionally influence to false emotion. For this reason it can be it can be helpful to use physiological signals like electroencephalogram (EEG) signal for study of human emotions. The emotions detected by EEG signals may be more advantageous because it is difficult to influence electrical brain activity intentionally. Moreover, the human brain is the origin of all the emotions and it is not possible to influence the brain activity …show more content…

APPLICATIONS OF EEG
The EEG methods are used in clinical and researching areas. Most of the EEG techniques used in research are not standardized sufficiently for clinical use.

1) Clinical use: EEG is typically used in the following clinical circumstances:
• to distinguish epileptic seizures from other types of spells, such as psychogenic non-epileptic seizures, syncope (fainting), sub-cortical movement disorders and migraine variants.
• to differentiate "organic" encephalopathy or delirium from primary psychiatric syndromes such as catatonia
• to serve as an adjunct test of brain death
• to prognosticate, in certain instances, in patients with coma
• to determine whether to wean anti-epileptic medications
• early stages of brain tumor can be diagnosed using EEG signals
• it is helpful in treatment of brain disorders such as autism, down syndrome, alzeihmers disease
• to detect brain damage due to a head injury or accident

EEG also has some characteristics that make it recommended method on behavioral testing(mood detecting). EEG can detect processing that does not require a response EEG can be used in subjects who aren’t capable of making motor responses. Some ERP components can be detected even when the subject is not attending to the stimuli. Unlike other means of studying reaction time, ERPs can explicate stages of processing (rather than only the final end

Dr. Richard Restak's The Secret Life Of The Brain

534 Words | 3 Pages

The part of the brain that receives virtually every stimuli is called the amygdala. The amygdala has the option of making an immediate emotional decision or passing the stimuli on to the frontal cortex area of the brain for a laborious analytical evaluation. In his book, The 7 Triggers to Yes, Russell H. Granger has taken this science and additional research and has identified seven factors that result in people making immediate decisions rather than passing the decision on to the frontal cortex for more evaluation. People who understand these seven triggers and apply them in their interaction with others, will produce greater results.

Visual Evoked Performance

1083 Words | 5 Pages

Visual Evoked Potential (VEP) is the electrical potentials evoked in the brain by visual stimuli and measure the initial stage of the reaction to visual stimulus (Thomas et al., 1991). Visual Evoked Potential has a lot of functions that can used by people nowadays such as to assess the central visual pathways and act as a tool for studying the cortical mechanisms of visuoperceptual processing. Besides, Visual Evoked Potential also can used in sports vision which is to see whether the performance of sports can be influenced by ability of athletes to maintain visuomotor processing during physical activity compared to non-athletes. Christenson and Winkelstein (1988) also showed that visual performances were found to be significantly better in

Biological And Cognitive Factors Involved In Emotion

1487 Words | 6 Pages

Emotion is a psychological or bodily change, interpreted by an individual who then decides on an appropriate behavioural response. There are six main emotions that can be identified- anger, disgust, happiness, sadness, surprise and fear. These are the emotions that are felt as well as recognised universally and have now become a part of most cultures. In this essay, I will demonstrate how biological and cognitive factors are involved in forming and appraising emotions, by using theories and studies to support my answer. I will first consider the biological factors, and then the cognitive factors in order to draw an informed conclusion The physiological explanation of emotion may be the arousal of the autonomic nervous system and the endocrine

Lying As Evidence In Research Papers

529 Words | 3 Pages

Lying is a way to mislead people or sometimes simply convince other people that it is true, which is not the actual case (Bhatt, 2009). Human-beings were always interested how to find out whether this particular person is lying or not. Nowadays, one of methods people start to use is fMRI or ERP. This particular method has a lot of strengths since relatively it is pretty accurate since brains “cannot lie”, nevertheless, it is a still questionable method since it is really hard to interpret the results because it is quite difficult to realize which areas of the brain is actually working more (in most cases just a little bit) than the others.

Plutchik's Eight Major Factors Affecting Human Thinking

(Plutchik, 1980) proposed the eight primary natures of emotion. First is, the joy, acceptance, fear, surprise, sadness, disgust, anger, and anticipation. He suggested that the complex emotions such as guilt and love are derived from combinations of primary emotions. Some says that when people are not using his or her brain every single of the day or even exercise it for some brain games or things that can make you think, other cells in the brain is shrinking. And that is one of the reason why people must often use or train his/her brain.

Charles Darwin's Developing Emotional Intelligence?

2403 Words | 10 Pages

Its roots can be traced back to the world of Charles Darwin who worked on the importance of emotional expression for survival and adaptation. The term first came into picture in the year 1985 when Wayne Payne published his doctoral thesis on A Study of Emotion: Developing Emotional Intelligence. This proposition was mainly based on the impression that society’s historical repression of emotions is the source of all sorts of problems such as depression, obsession, illness, religious conflict, fierceness and war. Prior to this work, this term had appeared in Leuner in 1966. In 1989, Stanley Greenspan put forth an EI model followed by Salovey and Mayer in 1990.

Emotions can make everything look blurry and generate doubt when it comes to truth, it can alter the results and conclusions lightly or in large quantities. When it comes to emotions, people tend to believe in what they are more emotionally attached to, their emotions influence in what someone believes something is true or not; the stronger the feeling, then you are more attached to something. This way of knowing affects directly and neutralizes the previous one, reasoning. When using emotions, people are blind to the truth, because they don’t what to see the reality of what they are attached to.
