Spreading photoparoxysmal EEG response is associated with an abnormal cortical excitability pattern.
Photosensitivity or photoparoxysmal response (PPR) is a highly heritable electroencephalographic trait characterized by an abnormal cortical response to intermittent photic stimulation (IPS). In PPR-positive individuals, IPS induces spikes, spike-waves or intermittent slow waves. The PPR may be restricted to posterior visual areas (i.e. local PPR with occipital spikes only) or spread to anterio...
متن کاملMotor cortical excitability in schizophrenia.
BACKGROUND Transcranial magnetic stimulation (TMS) provides a method to examine cortico-cortical motor excitability and hemispheric asymmetry in unmedicated and medicated schizophrenia patients. METHODS Fourteen right-handed schizophrenia patients (seven on conventional neuroleptics and seven medication-free) were compared with seven right-handed, age- and gender-matched normal control subjec...
متن کاملReduced cortical thickness associated with visceral fat and BMI
Structural brain imaging studies have shown that obesity is associated with widespread reductions in gray matter (GM) volume. Although the body mass index (BMI) is an easily accessible anthropometric measure, substantial health problems are more related to specific body fat compartments, like visceral adipose tissue (VAT). We investigated cortical thickness measures in a group of 72 healthy sub...
متن کاملOverweight is not associated with cortical thickness alterations in children
INTRODUCTION Several studies report an association between body mass index (BMI) and cortical thickness in adults. Some studies demonstrate diffuse cortical thinning in obesity, while others report effects in areas that are associated with self-regulation, such as lateral prefrontal cortex. METHODS This study used multilevel modeling of data from the NIH Pediatric MRI Data Repository, a mixed...
متن کاملDiminished Cortical Thickness is Associated with Impulsive Choice in Adolescence.
Adolescence is characterized by both maturation of brain structure and increased risk of negative outcomes from behaviors associated with impulsive decision-making. One important index of impulsive choice is delay discounting (DD), which measures the tendency to prefer smaller rewards available soon over larger rewards delivered after a delay. However, it remains largely unknown how individual ...
