Acquired brain injury (ABI) is a major public health problem in Massachusetts (Hackman et al, 2014) and includes traumatic brain injury (TBI), stroke, ABI-related infectious diseases, metabolic disorders affecting the central nervous system (brain and spinal cord), and brain tumor. Advances in emergency medical care and neurosurgery mean that more people are surviving severe traumatic brain injury (Trexler et al, 2014). Yet many patients with severe TBI in particular, are not receiving inpatient services after initial treatment (Hackman et al, 2014; CDC, 2014) or later that are known to be effective (Malec & Kean, 2015; Lewis & Horn, 2015; BI Commission, 2011; Kolakowsky-Hayner et al, 2000; Interviews)...

According to Jaak Panksepp's Affective Neuroscience Theory and the derived self-report measure, the Affective Neuroscience Personality Scales (ANPS), differences in the responsiveness of primary emotional systems form the basis of human personality. In order to investigate neuronal correlates of personality, the underlying neuronal circuits of the primary emotional systems were analyzed in the present fMRI-study by associating the ANPS to functional connectivity in the resting brain. N = 120 healthy participants were invited for the present study...

Resting-state fMRI studies have become very important in cognitive neuroscience because they are able to identify BOLD fluctuations in brain circuits involved in motor, cognitive, or perceptual processes without the use of an explicit task. Such approaches have been fruitful when applied to various disordered populations, or to children or the elderly. However, insufficient attention has been paid to the consequences of the loud acoustic scanner noise associated with conventional fMRI acquisition, which could be an important confounding factor affecting auditory and/or cognitive networks in resting-state fMRI...

COMMENT
Mariel G Kozberg, Elizabeth M C Hillman
In the adult brain, increases in local neural activity are accompanied by increases in regional blood flow. This relationship between neural activity and hemodynamics is termed neurovascular coupling and provides the blood flow-dependent contrast detected in functional magnetic resonance imaging (fMRI). Neurovascular coupling is commonly assumed to be consistent and reliable from birth; however, numerous studies have demonstrated markedly different hemodynamics in the early postnatal brain. Our recent study in J...

: The amygdala (AMG) has been repeatedly implicated in the processing of threatening and negatively valenced stimuli and multiple fMRI paradigms have reported personality, genetic, and psychopathological associations with individual differences in AMG activation in these paradigms. Yet the interchangeability of activations in these probes has not been established, thus it remains unclear if we can interpret AMG responses on specific tasks as general markers of its reactivity. In this study we aimed to assess if different tasks that have been widely used within the Affective Neuroscience literature consistently recruit the AMG...

The P300 is one of the most widely studied components of the human event-related potential. According to a longstanding view, the P300, and particularly its posterior subcomponent (i.e., the P3b), is driven by stimulus categorization. Whether the P3b relates to tactical processes involved in immediate responding or strategic processes that affect future behavior remains controversial, however. It is difficult to determine whether variability in P3b latencies relates to variability in response times because of limitations in the methods currently available to quantify the latency of the P3b during single trials...

INTRODUCTION: The clinical assessment of affective functioning has been slow to incorporate findings from affective neuroscience. Of particular interest in the current study is the assessment of affective word production. METHOD: In a series of four studies, we examined test-retest and interrater reliability for the Emotion Word Fluency Test (EWFT), basic construct validity with existing verbal fluency measures, physiological responses across verbal fluency tasks, and a novel scoring method to examine qualitative aspects of participant response sets...

I joined The Hastings Center this past summer, after graduating from Duke University, where I researched advancements in neuroscience and genomics and their import for law, ethics, and policy. This research required, to an extent, faith in the idea that researchers can identify pathways by which genes combine with epigenetic and environmental factors to affect neuronal activity and influence behaviors. Throughout my first months here, I have puzzled over broad critiques of "genomic hype" in recent literature, which clash with the optimistic rhetoric found in the Human Genome Project and the Precision Medicine Initiative...

Sex differences in brain development and aging are important to identify, as they may help to understand risk factors and outcomes in brain disorders that are more prevalent in one sex compared with the other. Brain imaging techniques have advanced rapidly in recent years, yielding detailed structural and functional maps of the living brain. Even so, studies are often limited in sample size, and inconsistent findings emerge, one example being varying findings regarding sex differences in the size of the corpus callosum...

REVIEW
Markus Hausmann
Biological sex and sex hormones are known to affect functional cerebral asymmetries (FCAs). Men are generally more lateralized than women. The effect size of this sex difference is small but robust. Some of the inconsistencies in the literature may be explained by sex-related hormonal differences. Most studies focusing on neuromodulatory properties of sex hormones on FCAs have investigated women during the menstrual cycle. Although contradictions exist, these studies have typically shown that levels of estradiol and/or progesterone correlate with the degree of FCAs, suggesting that sex differences in FCAs partially depend on hormonal state and day of testing...

Faces are key social stimuli that convey a wealth of information essential for person perception and adaptive interpersonal behaviour. Studies in the domain of cognitive, affective, and social neuroscience have put in light that the processing of faces recruits specific visual regions and activates a distributed set of brain regions related to attentional, emotional, social, and memory processes associated with the perception of faces and the extraction of the numerous information attached to them. Studies using neuroimaging techniques such as functional magnetic resonance imaging (fMRI) have allowed localizing these brain regions and characterizing their functional properties...

Neural stem/progenitor cells (NPSCs) express receptors for many inflammatory cytokines, with varying effects on differentiation and proliferation depending on the stage of development and the milieu of inflammatory mediators. In primary neurons and astrocytes, we recently showed that interferon gamma (IFNγ), a potent antiviral cytokine that is required for the control and clearance of many central nervous system (CNS) infections, could differentially affect cell survival and cell cycle progression depending upon the cell type and the profile of activated intracellular signaling molecules...

Art is a product of human creativity; it is a superior skill that can be learned by study, practice and observation. Modern neuroscience and neuroimaging enable study of the processes during artistic performance. Creative people have less marked hemispheric dominance. It was found that the right hemisphere is specialized for metaphoric thinking, playfulness, solution finding and synthesizing, it is the center of visualization, imagination and conceptualization, but the left hemisphere is still needed for artistic work to achieve balance...

Neuroscience and neurotechnology are increasingly being employed to assess and alter cognition, emotions, and behaviors, and the knowledge and implications of neuroscience have the potential to radically affect, if not redefine, notions of what constitutes humanity, the human condition, and the "self." Such capability renders neuroscience a compelling theme that is becoming ubiquitous in literary and cinematic fiction. Such neuro-SciFi (or "NeuroS/F") may be seen as eidolá: a created likeness that can either accurately-or superficially, in a limited way-represent that which it depicts...

INTRODUCTION: Prion diseases are protein conformation disorders and neither caused by viroid or virus but is a transmissible particle labeled a prion by Pruisner. Normal prion protein becomes infectious by a different folding, but the triggers are not known. Based on the characteristic brain pathology, they are grouped under spongiform encephalopathy affecting both man and animals. Estimated prevalence is one per million. Creutzfeldt-Jakob disease (CJD) registry from National Institute and Neurosciences (NIMHANS), Bengaluru, reported 69 cases in 30 years...

There is a growing research activity focusing on the brain heart cross-talk. A great variety of brain disorders affect the heart and recent developments in neurosciences have revealed the particular role of specific neuroanatomic sites on heart rhythm and rate, myocardial function and vascular tone. Cardiac radionuclide imaging plays a pivotal role in this setting, since not only helps elucidating underlying pathobiological mechanisms but in addition, it promises exciting possibilities for early identification of patients at risk of developing cardiovascular manifestations of certain neurological diseases...

In two experiments, patients with damage to the medial temporal lobe (MTL) and healthy controls produced detailed autobiographical narratives as they remembered past events (recent and remote) and imagined future events (near and distant). All recent events occurred after the onset of memory impairment. The first experiment aimed to replicate the methods of Race et al. [Race E, Keane MM, Verfaellie M (2011) J Neurosci 31(28):10262-10269]. Transcripts from that study were kindly made available for independent analysis, which largely reproduced the findings from that study...

In this debate with Lisa Feldman Barrett, I defend a view of emotions as biological functional states. Affective neuroscience studies emotions in this sense, but it also studies the conscious experience of emotion ("feelings"), our ability to attribute emotions to others and to animals ("attribution", "anthropomorphizing"), our ability to think and talk about emotion ("concepts of emotion", "semantic knowledge of emotion"), and the behaviors caused by an emotion ("expression of emotions", "emotional reactions")...
