Abnormal electroencephalographic (EEG) activity has been associated with various psychiatric disorders and behaviors, including depression, suicide, and aggression. We examined quantitative resting EEG in Hispanic female adolescent suicide attempters and matched normal controls. Computerized EEG measures were recorded at 11 scalp sites during eyes open and eyes closed periods from 16 suicide at...

Since the first human electroencephalogram (EEG) was recorded in 1929 by Hans Berger, enormous advances have been made in EEG recording technology and data analysis [1, 2]. The recording period was extended and long-term EEG monitoring became technically feasible when computer applications were introduced in the 1970s and digital EEG recording systems established. However, the use of long-term ...

Acute encephalopathy with biphasic seizures and reduced diffusion (AESD) is characterized by following febrile viral infections delayed of the cerebral white matter on magnetic resonance imaging (MRI) diffusion-weighted (DWI) (bright tree appearance, BTA). However, hypoxic AESD-mimicking findings has not been reported. We report a case due to suffocation concomitant BTA, mimicking AESD. On day ...

(EEG) and magnetoencephalography (MEG) are commonly reported in schizophrenia. Resting-state oscillatory findings have been inconsistent, likely because of the heterogeneity intrinsic to schizophrenia (such as age, symptoms, medications) as well as methodological issues (for example analysis procedures, EEG v.MEG). Most studies, however, observe more delta (1–4Hz) and theta (4–7Hz) resting-stat...

Multiscale entropy (MSE) analysis is a novel entropy-based approach for measuring dynamical complexity in physiological systems over a range of temporal scales. To evaluate this analytic approach as an aid to elucidating the pathophysiologic mechanisms in schizophrenia, we examined MSE in EEG activity in drug-naive schizophrenia subjects pre- and post-treatment with antipsychotics in comparison...

26 patients with temporal lobe epilepsy clinically documented by several abnormal interictal surface EEGs with typical unitemporal epileptiform activity and a normal CT scan were studied. Interictal 99mTC HMPAO brain SPECT and MRI were performed in all subjects. Abnormalities were shown in 61.5% of MRI (n = 16) and 65.4% of SPECT (n = 17). Hippocampal atrophy associated to a high signal on T2-w...

26 Electroencephalography (EEG) is a standard tool for monitoring brain states in humans. 27 Understanding the molecular and cellular mechanisms underlying diverse EEG rhythms can 28 be facilitated by using mouse models under molecular, pharmacological, or 29 electrophysiological manipulations. The small size of the mouse brain, however, poses a 30 severe limitation in the spatial information o...

The synchrony of neural firing is believed to underlie the integration of information between and within neural networks in the brain. Abnormal synchronization of neural activity between distal brain regions has been proposed to underlie the core symptomatology in schizophrenia. This study investigated whether abnormal synchronization occurs between the medial prefrontal cortex (mPFC) and the h...

Many brain diseases or disorders, such as depression, are known to be associated with abnormal functional connectivity in neural networks in the brain. Some bivariate measures of electroencephalography (EEG) for coupling analysis have been used widely in attempts to explain abnormalities related with depression. However, brain network evolution based on persistent functional connections in EEG ...

Objective: To evaluate the incidence, etiologies, clinical features and EEG findings of seizures among the neonates admitted to one medical center. Method: We retrospectively reviewed the medical records of neonates who were diagnosed to have neonatal seizure at the Neonatal Intensive Care Unit (NICU) of one medical center in Taiwan from January to December 2015. The clinical pictures, laborato...
