Tracking the Birth of Memories
Researchers have identified three distinct stages of brain development that occur before an episodic memory can form.... Read More...
How Electrical Stimulation Activates Neurons
A new study reveals frequency plays a key role in neural activation from electrical stimulation.... Read More...
Astrocytes Regulate Signal Speeds of Neurons
Researchers say astrocytes play a vital role in information processing by altering neurotransmission speeds and changing the thickness of myelin.... 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...
How the Brain’s Grid System Maps Mental Spaces
An international team of researchers have been able to demonstrate, with electrophysiological evidence, the existence of grid-like activity in the human brain.... Read More...
How the Brain Learns During Sleep
A new study sheds additional light on how the brain consolidates memory during sleep. Researchers report rapid fluctuations in gamma band activity in the hippocampus during nREM sleep helps facilitate memory reactivation.... Read More...
How the Brain Forgets on Purpose
Researchers implicate the dorsolateral prefrontal cortex and hippocampus in in our ability to actively forget a memory. ... Read More...
Brain Networks Responsible for Naming Objects Identified
Researchers have identified specific brain networks that helps us associate objects with their names. The study sheds light on how the brain connects meaning to words and could help explain why people with neurodegenerative diseases often have problems naming every day objects.... Read More...
Electricity Sparks Neural Diversity During Brain Development
Researchers report bioelectrical potential is a driving force for stem cells to generate different neuron types during embryogenesis.... Read More...
A Peek Into the Interplay Between Sleep and Wakefulness
Researchers have identified novel neural pathways that help regulate sleep and wakefulness.... Read More...
Your Brain with a Migraine
Researchers have identified electrical activity in the brain that is specific to the start of migraines. The new study reports spreading depolarization can be seen as a migraine begins, and an electrical current can be used to stop it in its tracks.... Read More...
