A research team has identified, for the first time in humans, and in a realistic environment, a key neurophysiological mechanism in memory formation: ripple-type brain waves—high-frequency electrical ...

These findings therefore reveal that aversive memory formation in humans depends on an amygdala-hippocampus "phase code": The amygdala coordinates the neuronal activity in the hippocampus, ...

In a recent study published in the journal Nature, researchers found that the recruitment of neurons to memory circuits is preceded by a cascade of molecular events induced during learning, which ...

Researchers have found that cells in the rat hippocampus -- a brain region that is essential for making memories -- are specifically organized into small clusters when fear-based memories are formed.

When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...

The aLTP process is activated when the brain is temporarily deprived of oxygen and glutamate levels increase. If aLTP is maintained for an extended period, this hijacks the normal functioning of the ...

Our brains store immense information about our experiences, feelings, and the world around us. Networks of neurons encode these signals as memories. These networks are called engrams. Select neurons ...

Scientists discover a new pathway to long-term memory formation in the brain that can bypass the formation of short-term memory. Researchers from Max Planck Florida Institute for Neuroscience have ...

T lymphocytes differentiate from naïve precursors upon antigen encounter into distinct effector and memory subsets. Following priming by antigen-presenting cells in lymphoid tissues, naïve CD4+ and ...

Modern lifestyles and dietary changes have significantly increased the consumption of high-fat foods, contributing to a steep rise in the prevalence of obesity, diabetes, and metabolic disorders.

Memory that serves to preserve past experiences and affect an animal’s future behavior is the most important cognitive activity; however, memory is not always stable in the brain and constantly fades ...
