Emotional intelligence (EI) is characterized by the ability to recognize emotional states in self and in others.This emotional recognition may be helpful in guiding behavior and in improving interpersonal relationships.It seems logical on a face validity level to assume that higher levels of EI would be good in the selection of students for medical school.However, there are few studies assessing EI in physicians. There are fewer studies that examine whether EI influences physician behavior, pati........ Read more »

Personality has often been conceptualized a a human feature shaped largely by nurture and environment.Unlike major neuroscience medicine disorders, personality features have been considered less influenced by brain structure and genetic influences.A recent brain structure (morphology) study puts these assumptions at risk.Roberta Riccelli along with colleagues in Italy and Florida State University studied brain structural features across 507 participants in the Human Connectome Project.All subjec........

Trump Spokesman’s Lecture on Media Accuracy Is Peppered With Lies
Nearly all American politicians lie, but few as blatantly as those affiliated with the present administration. How do they do it? Are they lacking a conscience? Do they believe their own lies? Do they start with small falsehoods, stretch the

Where is the septum?
The term septum, when used in reference to the brain (it is a common anatomical term used to refer to a partition), indicates a subcortical structure in the forebrain that is found near the midline of the brain. The septum in humans can be separated into two structures: the septum pellucidum and septum verum. Each of these is sometimes........ Read more »

William James authored a seminal book titled The Varieties of Religious Experience: A Study in Human Nature that was published in 1902.In this work, James reviewed the nature of religious experiences and noted a lack of scientific inquiry into this human phenomenon.James would have been extremely interested in a recent scientific inquiry into the religious experience from brain researchers at the University of Utah and Harvard University.In this study, functional magnetic resonance imaging (fMRI........

I ran into an interesting article at ScienceDaily providing data on a small sample size study of the anti-inflammatory drug celecoxib (Celebrex) in depression.Access the ScienceDaily report on this study by clicking HERE.This study focused on subjects with bipolar depression. All subjects were in a depressed phase and received the antidepressant drug escitalopram (Lexapro).Although only 55 subjects participated in this study, the results were significant and large.

Neuroscience medicine clinicians encounter patients every day who have both a mental and substance use disorder.This co-occurrence, or comorbidity, complicates diagnosis, treatment and outcome.The exact mechanism for this comorbidity issue is unclear.A recent study out of Washington University in St. Louis and King's College London provides some insight into this comorbidity issue.They examined participants in the Study of Addiction: Genetics and Environment (SAGE). These subjects provided genet........ Read more »

Depression is a common feature following traumatic brain injury (TBI). Post-TBI depression may be difficult to treat and evolve into a chronic depression syndrome.A recent published study demonstrates that prophylactic SSRI antidepressant treatment may reduce the incidence of depression following TBI.This study was conducted by investigators affiliated with Baylor College of Medicine and the Department of Psychiatry at the University of Iowa.Ninety four subjects were recruited to this randomized........

An fMRI study shows different dogs have different preferences for food and social interaction.A recent fMRI study investigates individual differences in dogs’ preferences for food and social interaction with their owner. The results have been widely – and erroneously – reported as showing that dogs prefer praise to food. In fact, the results paint a far more interesting picture of how brain activity predicts canine choice.I think most people feel subjectively that their dog loves them. The........ Read more »

In 1935, an ambitious neurology professor named Egas Moniz sat in the audience at a symposium on the frontal lobes, enthralled by neuroscientist Carlyle F. Jacobsen's description of some experiments Jacobsen had conducted with fellow investigator John Fulton. Jacobsen and Fulton had damaged the frontal lobes of a chimpanzee named "Becky," and afterwards they had observed a considerable behavioral transformation. Becky had previously been stubborn, erratic, and difficult to train, but post-operat........ Read more »

In my previous post, I highlighted a recent study of genetics and major depression from the 23andMe database.I have had a chance to review this manuscript in more detail. One of the findings of interest involved secondary marker or secondary phenotypes.Fifteen genetic loci were identified in this 23andMe sample using a discovery and replication data set.Secondary phenotypes with the highest correlation with the 17 SNPs identified in the study included (effect) :Taking a selective serotonin reupt........

Where is the periaqueductal gray?
The periaqueductal gray, or PAG, is an area of gray matter found in the midbrain. The PAG surrounds the cerebral aqueduct (hence the name periaqueductal) and occupies a column of brainstem that stretches about 14 mm long. There are no obvious visible anatomical divisions within the PAG, but researchers have divided the PAG into four columns based on differences in connectivity and function: the dorsomedial, dorsolater........

Inappropriate uncontrollable laughing or crying is common in many neuroscience medicine disorders including after traumatic brain injury or stroke. It can be socially embarrassing and restrict opportunities for social interaction.This loss of control over emotional responses is known by the term pseudobulbar affect or PBA. Until recently, few therapeutic options were available to treat this condition. Now a relatively new drug Nuedexta uses a combination of dextromethorphan and quinide to treat ........ Read more »

As basic and clinical sciences advance, it becomes increasing important to understand the role of multidisciplinary efforts in scientific progress. In this post, I propose rethinking and renaming the medically-related neuroscience disciplines into a new specialty called neuroscience medicine.Basic neuroscience research has evolved and emerged as a powerful discipline due to the increasing use of multidisciplinary research teams. Basic neuroscience involves collaboration of various scientifi........ Read more »
The development of speech and language impairment in dementia presents barriers in many clinical domains.One important clinical domain is assessment and management of pain. Dementia may preclude spontaneous or interview-elicited pain reporting.A report today in MedicalXpress noted reduced reporting of pain in patients with diabetes and cognitive impairment.I was able to locate one free full-text manuscript reviewing the prevalence of pain in various types of dementias.
