A neuron's dendrites typically do not cross one another. This intrinsic self-avoidance mechanism ensures unambiguous processing of sensory or synaptic inputs. Moreover, some neurons respect the territory of others of the same type, a phenomenon known as tiling. Different types of neurons, however, often have overlapping dendritic fields. We found that Down's syndrome Cell Adhesion Molecule (Dsc...

conclusions the results confirm the available literature data, while noting that self-harming is a preponderantly male behavior. the results also signal the need to create opportunities to instruct teachers to combat the resistances and stereotypes of psychological distress. results data analysis confirms an association between self- cutting and alcohol use, sexual harassments, school dropout, ...

The current study investigated the mediating effect of self-esteem in the relationship between overt narcissism and approach-avoidance goal orientations. Utilizing a sample of 958 participants, analyses revealed a slight suppression effect between overt narcissism and performance approach goal orientation, and a full mediation effect between overt narcissism and performance avoidance goal orien...

Dscam1 potentially encodes 19,008 ectodomains of a cell recognition molecule of the immunoglobulin (Ig) superfamily through alternative splicing. Each ectodomain, comprising a unique combination of three variable (Ig) domains, exhibits isoform-specific homophilic binding in vitro. Although we have proposed that the ability of Dscam1 isoforms to distinguish between one another is crucial for neu...

Recent commentaries have proposed conceptualizations of rumination in terms of both cognitive and behavioral avoidance. This study examined the relationship between rumination, avoidance and depression using a newly developed self-report measure of avoidance in depression, the Cognitive-Behavioral Avoidance Scale (CBAS) [Ottenbreit, N.D., & Dobson, K.S. (2004). Avoidance and depression: The con...

In the present research, a 3 2 model of achievement goals is proposed and tested. The model is rooted in the definition and valence components of competence, and encompasses 6 goal constructs: taskapproach, task-avoidance, self-approach, self-avoidance, other-approach, and other-avoidance. The results from 2 studies provided strong support for the proposed model, most notably the need to separa...
