Defense styles from the perspective of affective neuroscience

To our knowledge, no study has been carried out to observe which subcortical basic affective systems are related to which defense styles. Such a perspective may have the potential to reveal how defenses may interact with subcortical primary emotional systems (PES) and how they contribute to affect regulation. We aimed to analyze the relationship of immature, neurotic, and mature defenses with basic subcortical affects (CARE, PLAY, SEEK, SADNESS, FEAR, ANGER) within an affective neuroscientific perspective. In addition, we sought to explore the effect of psychiatric disorders in relation to PES and defenses, and observe gender effects, if any. The sample consisted of 703 university students, recruited online. The materials included the Turkish translations of the Affective Neuroscience Personality Scales (ANPS) and the Defense Style Questionnaire (DSQ). The correlations between ANPS and DSQ showed that the immature defenses increase as all negative emotions increase, whereas mature defenses increase as all positive emotions (except CARE) increase and all negative affects decrease (except ANGER). On the other hand, as neurotic defenses increase, CARE, FEAR and SADNESS simultaneously increase. Subjects who reported the presence of psychiatric disorders also reported higher FEAR, SADNESS, ANGER accompanied by higher immature defenses. Finally, male subjects reported higher immature defenses, whereas the females reported higher neurotic defenses, accompanied by higher CARE, SEEK, SADNESS, FEAR, and slightly lower PLAY. Investigating defenses through the lens of affective neuroscience offers the opportunity to link the abstract concept of defenses to increasingly well-understood neurobiology

Micromorphological and Anatomical Characteristics of the Genus Chrysophthalmum Schultz Bip. (Asteraceae) Growing in Turkey

The genus Chrysophthalmum (Asteraceae) is represented by five species in the world. Three species of this genus are naturally grown in Turkey. The species growing in Turkey are C. montanum (DC.) Boiss., C. dichotomum Boiss. and Heldr. and C. gueneri Aytac and Anderb. Except C. montanum; the other species are endemic for Turkey. In the present study, micromorphological and anatomical characteristics of these species by using light microscopy (LM) and scanning electronmicroscopy (SEM) have been comparatively presented for the first time. Themicromorphological studies are related to trichomes and cypsela. In anatomical studies, crosssections of the stem, and leaf have been examined. In addition, to show stomatal distribution and anatomy on adaxial and abaxial leaves, surface sections of the leaves have been taken and stomatal index calculated. The features of stems, leaves, trichomes and cypsela have been found to be significant to distinguish the species. Mesophyll structure, number of vascular bundles in midrib, presence or absence of sclerenchymatous fibers in leaf, trichome types, presence or absence of pappus in cypsela, presence or absence of hair on cypsela surface are important diagnostic characters. A diagnostic key based on combined leaf, trichome and cypsela characteristics of the Chrysophthalmum species has been given
