How Working Memory Gets You Through the Day
Researchers present a new model of working memory which helps explain how the brain holds information and executes volitional control.... Read More...
How the Brain Overcomes Its Own Limitations
Researchers have discovered how the brain attempts to compensate for poor performance in tasks which require complicated transformation, such as writing your name backwards.... Read More...
Electrical Properties of Dendrites Help Explain the Brain’s Unique Computing Power
Human dendrites have different electrical properties from those of other species, a new study reveals. Researchers report electrical signals weaken more as they flow along human dendrites, allowing small sections of dendrites to behave independently from the rest of the neuron. ... Read More...
Protein Has Unique Effects in the Neural Connections Related to Information Processing
A new study provides new insight into the molecular mechanisms that enable synaptic transmission critical for cognition.... Read More...
Detecting Fake News, At Its Source
Researchers have created a new deep learning system that can determine if a news outlet is accurate or biased based on only 150 articles published. The algorithm can also detect the political leanings of a news site. Researchers say fake news articles are more likely to use language that is hyperbolic, subjective and emotional.... Read More...
Even on Standardized Diet, Gut Flora Changes from Day to Day
Researchers say that, despite taking a standardized diet consisting of a liquid meal replacement, gut bacteria change frequently and unpredictably.... Read More...
New Sensor Tracks Dopamine in the Brain for More Than a Year
MIT researchers have developed a new sensor that is able to track and monitor dopamine in the brain for up to a year. The sensor could be a useful tool in monitoring dopamine levels in those with Parkinson's disease, depression and other conditions linked to dopamine deficiencies.... Read More...
AI Detects Depression in Conversation
Researchers at MIT have developed a new deep learning neural network that can identify speech patterns indicative of depression from audio data. The algorithm, researchers say, is 77% effective at detecting depression.... Read More...
Getting to the Roots of Pessimism
Researchers shed light on the role the caudate nucleus plays in pessimism. The study reports stimulating this area of the brain generates a negative outlook that clouds decision making. ... Read More...
To Understand Working Memory, Researchers Must Resolve This Debate
Researchers say, to better understand working memory, it is important to resolve the debate over how we hold and judge multiple pieces of information in mind.... Read More...
