Voluntary Termination

Does grief occur subsequent to elective abortion? This basic question is addressed using maternal-infant bonding as a basic theoretical framework. The temporal sequence of the three medical procedures: vacuum aspiration; dilitation and evacuation; and intrauterine induction, facilitated the testing of basic hypotheses deduced from bonding theory, as well as exploration of the grief reaction to the voluntary termination of a pregnancy. Grief associated with elective abortion was found to be symptomatically similar to grief experienced following involuntary fetal/infant loss, and may be initiated by the decision to terminate the pregnancy.

The basic question to be addressed in this chapter is: what is the status of the notions ‘inheritance’ and ‘default inheritance’ in the theoretical framework of Construction Morphology (CM)? This framework, developed in Booij (2010), assumes a hierarchical lexicon with both abstract morphological schemas and stored complex words that instantiate these schemas. The lexicon of a language can be modelled in such a way that the abstract word formation schemas dominate their individual instantiations. Thus, the lexicon is partially conceived of as a hierarchical network in which lower nodes, the existing complex words, can be assumed to inherit information from dominating higher nodes. Advantages of a full-entry theory over an impoverished entry theory are outlined, and the chapter includes discussion of polysemy, allomorphy, and the class of items that fall between derivatives and compounds using ‘affixoids’.

Mind wandering as data augmentation: How mental travel supports abstraction

Important Addition

Abstract Gilead et al. state that abstraction supports mental travel, and that mental travel critically relies on abstraction. I propose an important addition to this theoretical framework, namely that mental travel might also support abstraction. Specifically, I argue that spontaneous mental travel (mind wandering), much like data augmentation in machine learning, provides variability in mental content and context necessary for abstraction.

Rat Bone

This transmission electron microscopy (TEM) procedure was designed to examine a gram positive spore-forming bacillus in colony on various solid agar media with minimal artifact. Cellular morphology and organization of colonies embedded in Poly/Bed 812 resin (P/B) were studied. It is a modification of procedures used for undecalcified rat bone and Stomatococcus mucilaginosus.Cultures were fixed and processed at room temperature (RT) under a fume hood. Solutions were added with a Pasteur pipet and removed by gentle vacuum aspiration. Other equipment used is shown in Figure 3. Cultures were fixed for 17-18 h in 10-20 ml of RT 2% phosphate buffered glutaraldehyde (422 mosm/KgH2O) within 5 m after removal from the incubator. After 3 (30 m) changes in 0.15 M phosphate buffer (PB = 209-213 mosm/KgH2O, pH 7.39-7.41), colony cut-outs (CCO) were made with a scalpel.

Peripheral Facial Palsy

Abstract. This paper reviews adaptive and maladaptive mechanisms of cortical plasticity in patients suffering from peripheral facial palsy. As the peripheral facial nerve is a pure motor nerve, a facial nerve lesion is causing an exclusive deefferentation without deafferentation. We focus on the question of how the investigation of pure deefferentation adds to our current understanding of brain plasticity which derives from studies on learning and studies on brain lesions. The importance of efference and afference as drivers for cortical plasticity is discussed in addition to the crossmodal influence of different competitive sensory inputs. We make the attempt to integrate the experimental findings of the effects of pure deefferentation within the theoretical framework of cortical responses and predictive coding. We show that the available experimental data can be explained within this theoretical framework which also clarifies the necessity for maladaptive plasticity. Finally, we propose rehabilitation approaches for directing cortical reorganization in the appropriate direction and highlight some challenging questions that are yet unexplored in the field.
