Event-related brain potentials (ERPs) and magnetic fields (ERFs) were used to compare brain activity associated with selective attention to sound location or pitch in humans. Sixteen healthy adults participated in the ERP experiment, and 11 adults in the ERF experiment. In different conditions, the participants focused their attention on a designated sound location or pitch, or pictures present...

Arteriovenous malformations (AVMs) of the scalp are rare lesions. The clinical picture presents with complaints of increased scalp, scalp disfigurement, pain and neurological symptoms. Its origin can be congenital or traumatic. We present a case of giant scalp AVMs and its management, followed by a brief literature review on the subject. The diagnosis of scalp AVMs is based on physical examinat...

Scalp masses are commonly seen in clinical practice. They range from simple sebaceous cyst to malignant neoplasms. Clinical presentation is straight forward in most of the cases. Simple subcutaneous swelling till erosion of scalp and skull all can occur. However very few intracranial masses present with exophytic scalp swelling. This is because they have to erode dura, thick skull bone and all ...

Scalp is considered to be one of the ' immune zones' in leprosy. The involvement of the scalp in leprosy has been reported, though rarely. In the cases reported so far, the scalp was found to be affected mainly in bacilliferous leprosy and the involvement was mostly on the bald area of the scalp . However, in the present case a tuberculoid lesion was found on the hairy occipital area of the sca...

BACKGROUND The scalp is frequently affected in psoriasis patients, and pruritus can adversely affect the quality of life of affected patients. Few studies have assessed pruritus in scalp psoriasis. OBJECTIVE To determine the correlation among the clinical characteristics of pruritus, psoriasis scalp severity index (PSSI), and intraepidermal nerve fiber (IENF) density in psoriatic scalp lesion...

In this paper the method and performance data of ‘Boundary Element Method (BEM)’-based SMS-LORETA (Simultaneous Multiple Sources LORETA) are presented. According to these data the method is capable of locating efficiently multiple simultaneously active neural sources from scalp potential topographies automatically. BEM-based SMS-LORETA is a procedure to fully interpret sLORETA solutions, i.e., ...

Event-related potential studies in healthy adults and children have shown that stimuli signaling the need to stop elicit a robust, right-frontal-maximal N2 that is strongly reduced in children with attention-deficit hyperactivity disorder. To further investigate the mechanisms of normal response inhibition, the Stop Signal Task was applied to 12 healthy young adults using whole-head magnetoence...

The effects of attention were assessed on novelty P3 amplitude and scalp distribution elicited by environmental sounds in young and elderly volunteers who participated in either actively attended or ignored oddball conditions. For the young, novelty P3 amplitude decreased with time on task during both attend and ignore sequences. Amplitude decrements were greatest at frontal sites during the at...

The Panayiotopoulos type of occipital lobe epilepsy has generated great interest, but the particular brain areas involved in the peculiar seizure manifestations have not been established. We studied a patient with the syndrome, using high-resolution EEG and simultaneous EEG and functional magnetic resonance imaging (fMRI). Resolution of the scalp EEG was improved using a realistic spline Laplac...

Scalp cooling is a clinically proven treatment for addressing chemotherapy-induced alopecia (CIA). Previous studies show that the efficacy of this relies on accurate cranial data so designers can produce close-fitting scalp caps. The cephalic index often used, but are still accurate? We conducted pilot study to explore mass customisation
