“…In Go/No-go tasks using ERPs, significant increases were detected in the lingual gyrus in ADHD adults during the N2 time frame. This supports the theory that ADHD patients have to inhibit their reactions more strongly than healthy controls [74] . In our study, MPH decreased ReHo in the lingual gyrus in normal adults and this may also be related to improvement of attention and inhibition.…”

Methylphenidate (MPH) is one of the most commonly used stimulants for the treatment of attention deficit hyperactivity disorder (ADHD). Although several studies have evaluated the effects of MPH on human brain activation during specific cognitive tasks using functional magnetic resonance imaging (fMRI), few studies have focused on spontaneous brain activity. In the current study, we investigated the effect of MPH on the intra-regional synchronization of spontaneous brain activity during the resting state in 18 normal adult males. A handedness questionnaire and the Wechsler Adult Intelligence Scale were applied before medication, and a resting-state fMRI scan was obtained 1 h after medication (20 mg MPH or placebo, order counterbalanced between participants). We demonstrated that: (1) there were no significant differences in the performance of behavioral tasks between the MPH and placebo groups; (2) the left middle and superior temporal gyri had stronger MPHrelated regional homogeneity (ReHo); and (3) the left lingual gyrus had weaker MPH-related ReHo. Our findings showed that the ReHo in some brain areas changes with MPH compared to placebo in normal adults, even though there are no behavioral differences. This method can be applied to patients with mental illness who may be treated with MPH, and be used to compare the difference between patients taking MPH and normal participants, to help reveal the mechanism of how MPH works.

“…Tatking into account that the parameters of the Р3 closely correlate with the characteristics of attention, researchers extensively studied subjects with attention-deficit hyperactivity disorder (ADHD). In these individuals, reduction of the Р3 wave is observed [126,127]. There are indications that subjects with asocial behavior are distinguished by a higher Р3 amplitude upon presentation of a warning stimulus [128].…”

This review generalizes the data of modern studies of individual peculiarities of the spatial/temporal and amplitude characteristics of evoked EEG potentials (EPs) in humans. A brief description of EPs, characteristics of their components, sources of generation, and functional correlates is presented. Possible effects of the emotional significance of the stimulus and of individual peculiarities of the personality on the amplitude/temporal characteristics of EPs are considered. It is supposed that the aminergic cerebral systems play a crucial role in the formation of peculiarities of emotional responses, expression of the definite EP components, and biologically determined features of the human personality.

“…We expected to replicate behavioral slowing of RTs in adults with ADHD (10,(13)(14)(15)(16)(17)(18)(19)(20)(21). Since both perceptual (4,10,22) and response-related (5,(23)(24)(25) processes have been suggested as candidate sources of overt RT slowing, we further expected to observe delays in at least one of the analyzed ERPs.…”

“…This opens the potential for identifying latent internal traits of ADHDrelated slowing that bear candidacy for neurocognitive endophenotypes (27)(28)(29)(30). Of note, the few previous ERP studies of ADHD patients that investigated early sensory components provide F. Cross-Villasana et al 4 some evidence for alterations of sensory processes that mediate attentional (22) as well as subsequent response selection (23)(24)(25). However, none of these studies, or those in children with ADHD (27), used a design capable of disentangling the respective potential contributions of the three distinct, consecutive sub-stages of information processing to overt task performance.…”

“…However, the exact contributions of the respectively engaged internal processes-which might be the source(s) of the overt RT slowing-are not specified unequivocally (4,7,10,(13)(14)(15)(16)(17). Candidate processing levels are early sensory processes that guide the deployment of focal attention (4,10,22), stimulus-response translation processes that decide upon the correct motor response, and motor-response production processes (5,(23)(24)(25).…”
