New cause of brain bleeding immediately after stroke identified By discovering a new mechanism that allows blood to enter the brain immediately after a stroke, researchers have opened the door to new therapies that may limit or prevent stroke-induced brain damage. A complex and devastating neurological condition, stroke is the fourth-leading cause of death and primary reason for disability in the U.S. The blood-brain barrier is severely damaged in a stroke and lets blood-borne material into the brain, causing the permanent deficits in movement and cognition seen in stroke patients.
Neurons in brain tune into different frequencies for different spatial memory tasks Your brain transmits information about your current location and memories of past locations over the same neural pathways using different frequencies of a rhythmic electrical activity called gamma waves, report neuroscientists. The research may provide insight into the cognitive and memory disruptions seen in diseases such as schizophrenia and Alzheimer's, in which gamma waves are disturbed.
Rapid whole-brain imaging with single cell resolution A major challenge of systems biology is understanding how phenomena at the cellular scale correlate with activity at the organism level. A concerted effort has been made especially in the brain, as scientists are aiming to clarify how neural activity is translated into consciousness and other complex brain activities. One example of the technologies needed is whole-brain imaging at single-cell resolution. This imaging normally involves preparing a highly transparent sample that minimizes light scattering and then imaging neurons tagged with fluorescent probes at different slices to produce a 3D representation.
Common links between neurodegenerative diseases identified The pattern of brain alterations may be similar in several different neurodegenerative diseases, which opens the door to alternative therapeutic strategies to tackle these diseases, experts say.

Conceptual representation in the brain: Towards mind-reading? Your measured brain signals can reveal whether you are thinking about an animal or a tool. That's what neuroscientists discovered during her research, where she investigated the conceptual representation of words and objects in the human brain. This knowledge is useful for the development of tools that convert brain signals into speech.
'Brain training' overcomes tics in Tourette syndrome, study finds Children with Tourette Syndrome (TS) may unconsciously train their brain to more effectively control their tics. Teenagers diagnosed with Tourette Syndrome (TS) were slower than their typically developing peers when asked to perform a task that involved them simply moving their eyes to look at targets. However, they significantly outperformed their peers when the task was more demanding and required them to choose between looking at or away from targets. In this task they were as fast as their peers but made fewer eye movements in the wrong direction.

A photograph can be worth a thousand words There has long been a tradition of using photographs to capture, reveal, and expose. A photograph has the ability to arouse emotion – oftentimes, some would argue, more effectively than a verbal or written description.In a recent article in Social Dynamics, Rory du Plessis of the University of Pretoria (South Africa) has brought to life a case example of the power photographs can hold. In an analysis of two sets of photographs produced by the Grahamstown Lunatic Asylum between 1890 and 1907, du Plessis has revealed two very different faces of the institution – especially regarding the racial makeup of the patient population. The Grahamstown Lunatic Asylum opened in 1875 in what is now the Eastern Cape Province. Like other South African asylums of the period, Grahamstown adopted the moral treatment philosophy from Europe which viewed all aspects of the institution and the activities in which the patients were engaged as therapeutic in nature. During the period of focus of this particular study, Grahamstown was working to rebuild its image after receiving heavy criticisms regarding its success as a therapeutic institution. A new superintendent, Dr. Thomas Duncan Greenlees, arrived in 1890 and introduced a series of new recreational activities including: "picnics at neighbouring seaside towns, dances, dramatic entertainments, concerns, magic lantern entertainments, social evenings, cricket, and instrumental band, and croquet and lawn tennis for the women." At the same time, Greenless also created a system of differential treatment for the patient population of Grahamstown with only the White paying patients benefitting from these new activities and Black patients being engaged only in labour projects around the institution. The photographs examined by du Plessis bring to light these two very different worlds of the Grahamstown Lunatic Asylum.The first set of photographs were created explicitly for public consumption. These were published in annual reports and the institution's own periodical (which was sometimes reprinted in medical journals). As du Plessis highlights, these images were carefully orchestrated in order to portray an image of a successfully curative environment. White patients were portrayed in decorated rooms, dressed respectfully, and engaged in recreational activities popular during the period. Black patients, conversely, were featured in drab environments, oftentimes engaged in manual work, in scenarios of passivity and docility. du Plessis describes this set of public photographs as a "marketing tool" intended to normalize the activities of a curative environment (and recruit paying patients). In this context, the success of the supposed curative environment for White paying patients was evaluated through representations of class and wealth whereas the curative environment for Black patients was evaluated through the level of compliance engendered.Patients are seen being physically restrained by the hands of unseen attendants and nursesThe second set of photographs reveal a very different component of the institution's history: its stories of resistance, fear, and anxiety. These were created for internal use as part of the patient casebooks. From 1890 onwards, all patients of the Grahamstown Lunatic Asylum were photographed upon their admission. Much like the mug shots used by police departments, the admission photos focused on the face and upper body of the patient. In these silent portraits, du Plessis uncovered a range of powerful emotions exerted by the Black patients that were in stark contrast to the passivity represented in the first set of photographs. In acts interpreted as resistance, patients are seen in the casebook photographs being physically restrained by the hands of unseen attendants and nurses. In others, their gaze is averted as an act of defiance. A few other painful examples reveal the fear or anxiety expressed on the faces of those admitted to the institution.As du Plessis highlights in his article: "the taking of a photograph is never neutral." And more so: a picture may speak louder than words. _________________________________ du Plessis, R.
