An MRI-guided brain surgery technology goes global

An MRI-guided brain surgery technology goes global | Social Neuroscience Advances | Scoop.it

An MRI-guided laser system that allows surgeons to perform brain surgery on tumors and epileptic lesions in the brain is expected to become widely available to patients in need now that the technology has been acquired from Visualase Inc. by the global medical device company Medtronic, Inc., says a biomedical engineering professor from Texas A&M University who co-founded the company responsible for the technology.


The technology, says Gerard Coté, professor in the university’s Department of Biomedical Engineering and director of the Center for Remote Healthcare Technology, enables surgeons to pinpoint and destroy brain tumors and lesions with extreme precision and is a much less-invasive alternative to conventional surgery.


The advantage of this approach over other approaches for brain surgery, Coté explains, is that it can be performed while the patient is awake, requires no radiation and no skull flap (the large opening in traditional craniotomies), and is often performed in otherwise inoperable areas of the brain.


Traditional brain surgery, he explains, is usually a daylong operation that involves removing part of the skull, cutting through healthy brain matter and physically removing the problematic tissue. That procedure, he adds, can be followed by a weeklong hospital stay and prolonged recovery period. 


The technology developed by former Texas A&M students Ashok Gowda and the late Roger McNichols, conversely, can be completed in about four hours, and most patients can return home the following day, Coté says. 


Known as “Visualase,” the technology is already used in more than 45 hospitals, nationwide, including 15 pediatric hospitals. Before the surgical procedure, computer software first helps identify the targeted tissue so that it may be treated and the surrounding healthy tissue can be avoided, Coté explains. During the procedure, a small entry is made in the skull that allows a laser applicator (about the size of a pencil lead) to be inserted into the tissue. The patient is placed in the MRI, and a physician receives and reviews images to verify proper positioning of the laser applicator in the skull. The clinician then uses a laser to heat and destroy the problematic tissue while imaging the tissue being damaged in real time to ensure destruction of the problematic tissue and to avoid damaging healthy tissue. The laser applicator is then removed, and the scalp is closed with one stitch, Coté notes.

Men and Women Process Emotions in Different Ways: This Affects What They Remember — PsyBlog

Men and Women Process Emotions in Different Ways: This Affects What They Remember — PsyBlog | Social Neuroscience Advances | Scoop.it

Study of 3,000+ finds men and women process emotions differently and this affects what they remember. 

Women rate emotional images as more stimulating and are more likely to remember them than men, a new study finds.

While strong emotions tend to boost memory for both men and women, this neuroimaging study may help explain why women often outperform men on memory tests.

The results come from a very large study of 3,398 people who took part in four different trials.

Both men and women were asked to look at a series of pictures, some of which were emotionally arousing and others which were neutral.

Study: Therapeutic empathy and recovery from depression in cognitive-behavioral therapy: a structural equation model

Study: Therapeutic empathy and recovery from depression in cognitive-behavioral therapy: a structural equation model | Social Neuroscience Advances | Scoop.it
This study demonstrated that therapeutic empathy has a moderate-to-large causal effect on recovery from depression in a group of 185 patients treated with cognitive-behavioral therapy (CBT).


The authors simultaneously estimated the reciprocal effect of depression severity on therapeutic empathy and found that this effect was quite small. In addition, homework compliance had a separate effect on clinical recovery, over and above the effect of therapeutic empathy.


The patients of novice therapists improved significantly less than did the patients of more experienced therapists, when controlling for therapeutic empathy and homework compliance. Ss who terminated therapy prematurely were less likely to complete the self-help assignments between sessions, rated their therapists as significantly less empathic, and improved significantly less.


Ss with borderline personality disorder improved significantly less, but they rated their therapists as just as empathic and caring as other patients. The significance of these findings for psychotherapy research, treatment, and clinical training is discussed.

Reputation drives cooperative behaviour and network formation in human groups

Reputation drives cooperative behaviour and network formation in human groups | Social Neuroscience Advances | Scoop.it
Cooperativeness is a defining feature of human nature. Theoreticians have suggested several mechanisms to explain this ubiquitous phenomenon, including reciprocity, reputation, and punishment, but the problem is still unsolved. Here we show, through experiments conducted with groups of people playing an iterated Prisoner's Dilemma on a dynamic network, that it is reputation what really fosters cooperation. While this mechanism has already been observed in unstructured populations, we find that it acts equally when interactions are given by a network that players can reconfigure dynamically. Furthermore, our observations reveal that memory also drives the network formation process, and cooperators assort more, with longer link lifetimes, the longer the past actions record. Our analysis demonstrates, for the first time, that reputation can be very well quantified as a weighted mean of the fractions of past cooperative acts and the last action performed. This finding has potential applications in collaborative systems and e-commerce.

Oxytocin Improves Empathy in Frontotemporal Dementia

Oxytocin Improves Empathy in Frontotemporal Dementia | Social Neuroscience Advances | Scoop.it
Intranasal administration of oxytocin twice daily for 1 week was safe and well tolerated and showed preliminary signs of improvement in symptoms of apathy and loss of empathy in patients with frontotemporal dementia, according to a new study.


The study, published in the January 13 issue of Neurology, was led by Elizabeth C. Finger, MD, Western University, London, Ontario, Canada


Dr. Finger explained to Medscape Medical News that frontotemporal dementia is the second most common cause of presenile dementia. "It typically starts in the 50s or 60s and appears to have a different pathology to Alzheimer's, with loss of empathy being the hallmark symptom in the most common subtype — known as behavioral variant."

Memory and burstiness in dynamic networks

We introduce a class of complex network models which evolve through the addition of edges between nodes selected randomly according to their intrinsic fitness, and the deletion of edges according to their age. We add to this a memory effect where the attractiveness of a node is increased by the number of edges it is currently attached to, and observe that this creates burst-like activity in the attachment events of each individual node which is characterised by a power-law distribution of inter-event times. The fitness of each node depends on the probability distribution from which it is drawn; we find exact solutions for the expectation of the degree distribution for a variety of possible fitness distributions, and for both cases where the memory effect either is, or is not present. This work can potentially lead to methods to uncover hidden fitness distributions from fast changing, temporal network data such as online social communications and fMRI scans.
