Impaired future thinking may be a core aspect of impulsive decision making. Recent efforts to understand the brain processes that underlie impulsivity have suggested a role for the frontal lobes. However, future thinking is unlikely to be a unitary process, and the frontal lobes are not a homogeneous entity. The present study contrasted the effects of dorsolateral and ventromedial frontal lobe ...

the suppression of the regenerative chatter phenomenon in turning process via the variation of the frequency and amplitude of the spindle motor excitation is carried out in this research. a programmable inverter is employed for variable periodic excitation of the spindle motor. a set of turning experiments is designed and performed on a number of conical work pieces both in constant spindle spe...

Paired imaging studies consisting of computed tomography (CT) and magnetic resonance imaging (MRI) were performed in eight dogs to evaluate subjectively whether MRI is superior to CT in detecting intracalvarial changes associated with canine nasal neoplasia. Imaging in four anatomical regions (caudal ethmoturbinates, cribriform plate, frontal sinuses, and the olfactory peduncle of the frontal l...

BACKGROUND Studies have emphasized on the frontal EEG asymmetry as a mediator of emotional states. This research was aimed to examine the overall and asymmetric activities of the brain lobes under the affective states. METHODS A coupling EEG was recorded in an eye closed awakened condition from 40 right handed female students under the baseline and affective states. RESULTS Bilaterally decr...

The study aimed to assess central nervous systems in children diagnosed with Fetal Alcohol Spectrum Disorder (FASD), using the techniques of magnetic resonance (MRI). analyses considered 200 children, both female and male, aged 6–17 years, FASD, as well 32 healthy sexes, 6–16 years. Brain anomalies linear surface area measurements brain corpus callosum were assessed. 1H MRS DWI signals evaluate...

Cu/Zn superoxide dismutase (SOD) is part of the defense mechanism that protects cells from being damaged by reactive oxygen species. During metamorphosis of the nervous system, neurons undergo various fates, which are all coupled to high metabolic activities, such as proliferation, differentiation, pathfinding, and synaptogenesis. We describe the pattern of SOD immunoreactivity of identified ne...

It is becoming clear that inflammation plays a significant role in a number of neurological and psychiatric conditions. Post mortem brain samples in Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, multiple sclerosis, schizophrenia and most recently autism spectrum condition, all exhibit neuroglial activation and inflammatory markers within the CSF. Many questions remain...
