Brain research provides clues to what makes people think and behave differently
Differences in the physical connections of the brain are at the root of what make people think and behave differently from one another. Researchers reporting in the Cell Press journal Neuron shed new light on the details of this phenomenon, mapping the exact brain regions where individual differences occur. Their findings reveal that individuals' brain connectivity varies more in areas that relate to integrating information than in areas for initial perception of the world. (2013-02-06)

A new means of neuronal communication discovered in the human brain
An international research group has discovered in the human brain a new functional coupling mechanism between neurons, which may serve as a communication channel between brain regions. (2020-12-17)

New brain cells listen before they talk
Newly-created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival -- which has implications for using adult stem cells to replace those lost by trauma or neurodegeneration. (2007-10-30)

Crime scene schizophrenia -- 30 genes under suspicion
The research group led by Prof. Alex Schier, Director of the University of Basel's Biozentrum, has identified 30 genes associated with schizophrenia.

Where the brain makes sense of speech
Researchers have identified regions of the brain where speech sounds are perceived as having abstract meaning, rather than as just a stream of sensory input. They said their identification of the regions demonstrates that the understanding of speech does not just emerge from lower-level processing of speech sounds, but involves a specialized perceptual region. Steven Small and his colleagues published their findings in the Dec. 20, 2007, issue of the journal Neuron, published by Cell Press. (2007-12-19)

Parts of brain involved in social cognition may be in place by age 6
By scanning the brains of children ages 6 to 11 as they listened to children's stories, researchers have for the first time investigated brain regions associated with social cognition in human children. Researchers found that one of the brain regions, the right tempero-parietal junction, appeared to change its function between the ages of 6 and 11. This research has implications for the study of atypical social development, as happens in autism. (2009-07-15)

Diattenuation imaging -- a promising imaging technique for brain research
A new imaging method provides structural information about brain tissue that was previously difficult to access. Diattenuation imaging, developed by scientists at Forschungszentrum Jülich and the University of Groningen, allows to differentiate, e.g., regions with many thin nerve fibers from regions with few thick nerve fibers. With current imaging methods, these tissue types cannot easily be distinguished. (2019-03-19)

Scientists made a single-cell-resolution map of brain genes in humans and other primates

Frequent alcohol drinking kills new brain cells in adults, females are more vulnerable
Researchers from The University of Texas Medical Branch at Galveston recently discovered that alcohol killed the stem cells residing in adult mouse brains.

The findings are available in Stem Cell Reports. (2017-11-09)

Map of broken brain networks shows why people lose speech in language-based dementia
Scientists have drawn a map that illustrates three regions in the brain of people with primary progressive aphasia (PPA) that fail to talk to each other, inhibiting a person's speech production, word finding and word comprehension. The map can be used to target those brain regions with therapies, such as transcranial magnetic stimulation (TMS), to potentially improve an affected person's speech. (2019-09-01)

Have we met before? Scientists show why the brain has the answer
Have you ever been approached by someone whose face you recognise but whose name you can't remember? Neuroscientists at the University of Bristol have identified the reasons behind why we are, at times, unable to link a face to a name. (2011-08-04)

Smart people have better connected brains
Differences in intelligence have so far mostly been attributed to differences in specific brain regions. However, are smart people's brains also wired differently to those of less intelligent persons? A new study published by researchers from Goethe University Frankfurt (Germany) supports this assumption. In intelligent persons, certain brain regions are more strongly involved in the flow of information between brain regions, while other brain regions are less engaged. (2017-11-22)

The big picture: Long-term imaging reveals intriguing patterns of human brain maturation
Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain.

When it comes to learning and memory, the brain is a co-operative continuum
Drs. Tim Bussey and Lisa Saksida have introduced a new theory about memory. Based on their studies, they have found segregation of specific memory functions in different brain regions may not be the best model. Instead, the brain appears to be a co-operative in which simultaneous and harmonized function are needed to effectively learn and store memories. This research may provide new insight into memory disorders and other brain ailments such as Alzheimer's disease. (2017-05-31)

Brain 'network maps' reveal clue to mental decline in old age
The human brain operates as a highly interconnected small-world network, not as a collection of discrete regions as previously believed, with important implications for why many of us experience cognitive declines in old age, a new study shows. Australian researchers have mapped the brain's neural networks and for the first time linked them with specific cognitive functions, such as information processing and language. (2011-02-07)

Brain cells divide the work to recognize bodies
Specific regions of the brain are specialized in recognizing bodies of animals and human beings. By measuring the electrical activity per cell, scientists from KU Leuven, Belgium, and the University of Glasgow have shown that the individual brain cells in these areas do different things. Their response to specific contours or body shapes is very selective. (2016-04-28)

Small but distinct differences among species mark evolution of human brain
The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity. However, all regions of the human brain have molecular signatures very similar to those of our primate relatives, yet some regions contain distinctly human patterns of gene activity that mark the brain's evolution and may contribute to our cognitive abilities, a new Yale-led study has found. (2017-11-23)

How to map brain connections using DNA barcodes
Detailed wiring diagrams--connectomes--for the brain are critical for understanding brain development, function, and disease. CSHL scientists found a way to use a large set of short snippets of DNA to label neurons, increasing the number of paths that can be traced in a single experiment versus other brain mapping techniques. (2020-07-14)
