Role of Hippocampus in future thinking and scene construction
Over the past decade, researchers have learned that the hippocampus historically known for its role in forming memories is involved in much more than just remembering the past; it plays an important role in imagining events in the future. Yet, scientists still do not know precisely how the hippocampus contributes to episodic imagining until now.…

Research shows new understanding on how working memory is stored in brain
Working memory is integral part of cognitive process and it involves short term memory. Previous research shown that it depends on sustained, elevated brain activity. However researchers at University of Wisconsin-Madison have shown that humans can hold information in working memory via “activity-silent” synaptic mechanisms. Their study is published in journal Science. According to Brad Postle,…

Researchers found pathology behind traumatic brain injury and possible theraputic target
Traumatic brain injury (TBI) can have various harmful long-term neurological effects, including problems with vision, coordination, memory, mood, and thinking. According to the Centers for Disease Control and Prevention, traumatic brain injury from a head injury is a leading cause of death and disability in the United States, and close to 5 million Americans—soldiers and…

New Imaging technique maps serotonin activity in Brain
Serotonin is a neurotransmitter that’s partly responsible for feelings of happiness and for mood regulation in humans. This makes it a common target for antidepressants, which block serotonin from being reabsorbed by neurons after it has dispatched its signal, so more of it stays floating around the brain. Now MIT researchers have developed an imaging…
