Researchers gain new insight into how motor neurons in the brain die during ALS
When faced with making choices, but lack sufficient evidence to guarantee success, our brain uses elapsed time as a proxy for task difficulty to calculate how confident we should be, a team of neuroscientists has found. Their findings help untangle the different factors that contribute to the decision-making process.
Investigators found that using intra-arterial treatment to remove a stroke-causing blood clot in a large vessel supplying blood to the brain provides better outcomes than trying to dissolve the clot using a clot-busting drug (lytic) alone.
Using an innovative technique combining genetic analysis and mathematical modeling with some basic sleuthing, researchers have identified previously undescribed microlesions in brain tissue from epileptic patients. The millimeter-sized abnormalities may explain why areas of the brain that appear normal can produce severe seizures in many children and adults with epilepsy.
An imaging scan called SPECT records brain activity during epileptic seizures. The scan pinpoints where seizures originate, and helps in the planning of surgery to remove the part of the brain responsible for seizures.
For up to one in five Americans over age 65, getting older brings memory and thinking problems. It may seem like part of getting older - but officially, it’s called mild cognitive impairment or MCI. A new definitive look at the evidence about what works and what doesn’t in MCI should help doctors and the seniors they treat.

Both positive and negative experiences influence how genetic variants affect the brain and thereby behaviour, according to a new study. “Evidence is accumulating to show that the effects of variants of many genes that are common in the population depend on environmental factors. Further, these genetic variants affect each other,” explained Sheilagh Hodgins of the University of Montreal and its affiliated Institut Universitaire en Santé Mentale de Montréal.

Salk scientists develop a theory to explain how animals gather information and switch attention
While many different combinations of genetic traits can cause autism, brains affected by autism share a pattern of ramped-up immune responses, an analysis of data from autopsied human brains reveals. The study, a collaborative effort between Johns Hopkins and the University of Alabama at Birmingham, included data from 72 autism and control brains.
Whether we’re paying attention to something we see can be discerned by monitoring the firings of specific groups of brain cells. Now, new work from Johns Hopkins shows that the same holds true for the sense of touch. The study brings researchers closer to understanding how animals’ thoughts and feelings affect their perception of external stimuli.
We know that everyday events can be easy to forget, but dangerous experiences that trigger fear can remain engraved in the brain for years. Now, scientists from NYU and Japan’s RIKEN Brain Science Institute have added to our understanding how this occurs.
