“…Scheeringa et al (2011) also found alpha suppression reflects the magnitude of the MRI response in visual cortex during a visual attention task. The reason why attenuation was stronger for the unfamiliar objects in the occipital alpha band may be a result of a novelty effect, since previous research has demonstrated stronger occipital alpha desynchronization following presentation of a novel stimulus compared to a familiar expected stimulus (Harrison, 1946;Mulholland and Runnals, 1962).…”

Whilst previous research has linked attenuation of the mu rhythm to the observation of specific visual categories, and even to a potential role in action observation via a putative mirror neuron system, much of this work has not considered what specific type of information might be coded in this oscillatory response when triggered via vision. Here, we sought to determine whether the mu rhythm contains content-specific information about the identity of familiar (and also unfamiliar) graspable objects. In the present study, right-handed participants (N=27) viewed images of both familiar (apple, wine glass) and unfamiliar (cubie, smoothie) graspable objects, whilst performing an orthogonal task at fixation. Multivariate pattern analysis (MVPA) revealed significant decoding of familiar, but not unfamiliar, visual object categories in the mu rhythm response. Thus, simply viewing familiar graspable objects may automatically trigger activation of associated tactile and/or motor properties in sensorimotor areas, reflected in the mu rhythm. In addition, we report significant attenuation in the central beta band for both familiar and unfamiliar visual objects, but not in the mu rhythm. Our findings highlight how analysing two different aspects of the oscillatory response, either attenuation or the representation of information content, provide complementary views on the role of the mu rhythm in response to viewing graspable object categories.

“…LENNART NILSSON AND GUDMUND J. W. SMITH A connection between relatively high EEG frequencies on the one hand and syndromes of anxiety, tension and emotional states on the other is reported by many investigators (Berger, 1933;Durup & Fessard, 1935;Davis & Davis, 1936;Loomis et al, 1936;Jasper & Cruikshank, 1937;Jasber & Andrews, 1938;Darrow et al, 1942;Finlty, 1944;Brazier et al, 1945;Strauss, 1945;Cohn, 1946;Harrison, 1946;Faure, 1947;Monnier, 1950;Ulett et al, 1953;Kennard et al, 1955). This is not surprising since the reticular system can be activated by endogenous as well as exogenous stimulation (Magoun, 1960).…”

PROBLEMThe major purpose of this paper is to review the literature on EEG associated with psychological functioning as assessed by psychophysical, psychomotor and personality parameters. With the introduction of the EEG procedure in 1929 by Berger(76), expectations were that a tool had been found to correctly diagnose different types of brain disorders. Although the EEG became a useful tool for diagnosing such conditions as brain tumors and epilepsy, it was recognized that much work needed to be done before it would become apparent just how electrical impulses in the brain are related to sensations, thoughts, and affect.During the past two decades investigators have made progress in the pursuit of this problem by studying the brain waves of trained or conditioned animals and have established some definite associations between the wave patterns and conditioned behavior. In addition, identification of sleeping and waking patterns have been accomplished. More recently, a number of studies have attempted to relate EEG readings to psychomotor functioning and personality characteristics.Conditioning. The studies reported here are cited as evidence that alpha blocking response can be conditioned. Most of the early experiments in conditioning were performed on animals. A number of ''-73) have demonstrated that the alert response in the early stage of conditioning is fairly long lasting and involve! most of the brain. As the learning progresses, the response becomes shorter and more focused. This would indicate that the arousal is limited to the portions of the brain needed for a given response. A common, everyday observation supporting this contention is that an individual exerts less conscious effort in performance of a task after the attainment of a new skill.Roland(89) demonstrated that when the auditory cortex of cats was destroyed, EEG indicated that these animals could still discriminate between click and tone stimuli. Conditioning has also been demonstrated in man by Jasper and Shagass(S8), shag as^@^), and M n~k h i n a (~~) . Morrell and Ross' ('*) findings indicated that by successively pairing a sound stimulus with a light stimulus, alpha rhythm could be conditioned to respond to the sound stimulus alone. Photic stimulation was shown to have no significant effect on the formation of the conditioned avoidance response by Milstein and Stevens(@@). To date, conditioning of the alpha response does not appear to be related to any standard psychological tests and investigators have not been successful in relating conditioning to any specific intellectual function or personality characteristic. Reaction time.Reaction time has been used as a successful technique in differentiation between mental abnormality and normal functioning. A review of the literature in this area reveals that as early as 1937 Huston, Shakow and Riggs(S6) and Rodnik and Shakow studied reaction time of schizophrenic patients and demonstrated that their reaction time was generally slower than that of normal Ss. In connection with the EEG Travis(1w...
