Sensory stimuli evoke spiking activities patterned across neurons and time that are hypothesized to encode information about their identity. Since the same stimulus can be encountered in a multitude of ways, how stable or flexible are these stimulus-evoked responses? Here, we examined this issue in the locust olfactory system. In the antennal lobe, we found that both spatial and temporal featur...

Multifocal micronodular pneumocyte hyperplasia (MMPH) is rare entity seen mostly in patients with the tuberous sclerosis complex (TSC). We present the case of a 50 year old woman with TSC (confirmed TSC2 mutation) found to have multiple ground glass opacities with an upper lobe predominance on a screening chest CT. No abnormalities were detected in other viscera. A thoracoscopic lung biopsy obt...

Homoclinic and heteroclinic tangles are fundamental phase space structures that help organize the transport defined by a chaotic map on a two-dimensional phase space. Previous work introduced the technique of “homotopic lobe dynamics” to study the topology of a homoclinic tangle. The present work generalizes homotopic lobe dynamics to describe the topology of a network of nested homoclinic and/...

  Background: This study compares the clinical characteristics of patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) with those who have temporal lobe epilepsy (TLE) due to other etiologies.   Methods : In this retrospective study all patients with a clinical diagnosis of TLE were recruited in a referral outpatient epilepsy clinic at Shiraz University of Medical Sc...

ovine pulmonary adenocarcinoma (opa) is a contagious and transmissible lung cancer of sheepresembling human bronchiolo-alveolar carcinoma. in the present study, lungs of 9400 sheep slaughtered infars province, iran were examined morphopathologically. the opa was diagnosed in the lungs of 21(0.22%) out of 9400 sheep. frequency of involvement of different lobes in the affected lungs was includeda...

The development of a placenta is complex process that occurs without clinically significant issue in most pregnancies. At times, however, the develops way isolates an island placental tissue away from main body, connected only by unprotected vasculature within amniotic membranes. vessels this succenturiate lobe are vulnerable both to compression or laceration, threatening antepartum period with...

epilepsy is one of the most common chronic disorders affecting individuals of all ages. a greater understanding of pathogenesis in epilepsy will likely provide the basis fundamental for development of new antiepileptic therapies that aim to prevent the epileptogenesis process or modify the progression of epilepsy in addition to treatment of epilepsy symptomatically. therefore, several investiga...
