Consciousness: a neurological perspective

Consciousness is a state so essentially entwined with human experience, yet so difficult to conceptually define and measure. In this article, we explore how a bidimensional model of consciousness involving both level of arousal and subjective awareness of the contents of consciousness can be used to differentiate a range of healthy and altered conscious states. These include the different sleep stages of healthy individuals and the altered states of consciousness associated with neurological conditions such as epilepsy, vegetative state and coma. In particular, we discuss how arousal and awareness are positively correlated in normal physiological states with the exception of REM sleep, while a disturbance in this relationship is characteristic of vegetative state, minimally conscious state, complex partial seizures and sleepwalking.     

Comparing Maltreating and Foster Families in Italy

Maltreating and foster families belong to different research areas and have rarely been considered together. This exploratory study compared maltreating and foster families to demonstrate an integrated approach that overcomes the dichotomic view that often separates problematic families from those who have resources. This study had 81 participants: 48 maltreating parents and 33 foster parents and the children who were in foster care. We examined family functioning (FES), adult attachment styles (ASQ) and foster children’s strengths and difficulties (SDQ) in maltreating and foster families to examine the differences and similarities between families. Both types of families had significant differences on the FES and ASQ scales. Maltreating families had a stronger orientation to succeed and a family profile that was more orientated towards independence. Maltreating parents had higher scores on the scale that measured discomfort with closeness than foster families. However, both family types had a high level of confidence. Many foster children had SDQ scores that were in the borderline and problem categories. These components may promote a theoretical view of an integrated model for family and children’s problems that promotes children’s welfare and supports maltreating parents. Practitioners can build on parent’s strengths or protective factors and provide services to address less developed areas.     

The precuneus and consciousness

This article reviews the rapidly growing literature on the functional anatomy and behavioral correlates of the precuneus, with special reference to imaging neuroscience studies using hamodynamic techniques. The precuneus, along with adjacent areas within the posteromedial parietal cortex, is among the most active cortical regions according to the "default mode" of brain function during the conscious resting state, whereas it selectively deactivates in a number of pathophysiological conditions (ie, sleep, vegetative state, drug-induced anesthesia), and neuropsychiatric disorders (ie, epilepsy, Alzheimer's disease, and schizophrenia) characterized by impaired consciousness. These findings, along with the widespread connectivity pattern, suggest that the precuneus may play a central role in the neural network correlates of consciousness. Specifically, its activity seems to correlate with self-reflection processes, possibly involving mental imagery and episodic/autobiographical memory retrieval.     

Testing Children’s Mentalizing in Middle Childhood: Adopting the Child and Adolescent Reflective Functioning Scale with Clinical and Community Children

Journal of Child and Family Studies - Beginning with Ensink’s seminal study (2015), the field entered a new era in which we were able to measure mentalizing in school-aged children. The goal...     

Brain mechanisms of altered consciousness in focal seizures

Consciousness is a central concept in epileptology, relevant to the understanding of both focal and generalized seizures. Within focal seizures, impairment of consciousness has long been considered as the main criterion differentiating complex partial seizures (CPS) from simple partial seizures With the development of improved tools for investigating human brain function, new insights into the brain mechanisms of altered consciousness in CPS have become available. This paper reviews the existing literature on how the currently available methods can be used to address the fundamental issue of how CPS alter consciousness.
