A new study reveals a correlation between multimedia multitasking, memory loss, and difficulties in maintaining attention. Read More
Pigment-dispersing factor, a signalling protein that helps the brain keep track of time, also helps to regulate memory formation. Read More
Astrocytes respond to cocaine exposure in the brains of mice by promoting the formation of new synapses. Read More
For older adults, some sedentariness may not be as bad for memory as believed, especially if physical activity benchmarks are being met. Read More
Researchers have identified a signaling pathway in the hippocampus that plays a critical role in creates novel memories about new environments. Read More
The hunger hormone ghrelin doesn't just influence where and when animals eat, it also appears to have an impact on memory. Disrupting signaling of ghrelin to the vagus nerve caused rats to forget they had just eaten, even though the animals remembered they had just had access to food. Findings suggest disrupted ghrelin signaling could negatively impact episodic memory. Read More
People are better able to recall the location of high-calorie foods over healthier options. Findings suggest spatial memory may have evolved to prioritize the location of higher-calorie foods. Read More
Children who learn to play musical instruments have an edge over their non-musical peers when it comes to learning, memory, and attention. Those who learn musical instruments showed greater activity in the inferior frontal gyrus and the supramarginal gyrus, which are parts of the "phonological loop". The phonological loop is associated with working memory involved in auditory processing. Researchers say learning an instrument also has positive implications on creativity and quality of life overall for children. Read More
Protein synthesis in different amygdala neuron populations is essential for storing information about threat and safety. Read More
The retrieval of mitochondria via a feedback loop is vital to sustaining synaptic transmission. Read More
Engram cells encode details of memories as they are formed. These cells become reactivated when a memory is recalled. The process is controlled by remodeling of chromatin in the cells. Read More
