Researchers identify the sleep mechanism which enables the brain to consolidate emotional memory. Additionally, they discovered a popular sleep medication heightens the response to and recollection of negative memories.
Researchers have discovered how the Arc protein regulates neuronal activity, providing clues into the brain's ability to form long-term memories.
Researchers question why numerous different RNAs are transported to synapses. One reason, they suggest, is that they are stored to later help maintain long-term memory.
If only there were a way to forget that humiliating faux pas at last night's dinner party. It turns out there's not one, but two opposite ways in which the brain allows us to voluntarily forget unwanted memories, according to research.
Frequently, as many as one thousand signals rain down on a single neuron simultaneously. To ensure that precise signals are delivered, the brain possesses a sophisticated inhibitory system. Scientists have now illuminated how this system works.
Researchers recently localised and identified the most important types of nerve cells involved in forming positive and negative memories of a fruit fly. All four nerve cell types they discovered use dopamine to communicate with other nerve cells. Three of the nerve cell types assume various functions in mediating negative stimuli, while the fourth enables the fly to form positive memories.
New memory research suggests that lactate and astrocytes have more important roles in long-term memory formation than previously thought by...
