When a long-term memory forms, some brain cells experience a rush of electrical activity so strong that it snaps their DNA. Then, an inflammatory response kicks in, repairing this damage and helping ...

Newly decoded brain circuits make memories more stable as part of learning, according to a study led by NYU Langone Health researchers. The entorhinal/hippocampal circuit is known from past studies to ...

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 ...

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 ...

A new study uses optogenetics and roflumilast to prove sleep deprivation blocks memory retrieval, not storage.

Boosting the production of new neurons in a mouse model of Alzheimer’s disease (AD) leads to the rescue of memory formation, according to a new study led by researchers from the University of Illinois ...

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 ...

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.

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 ...

Certain nerve cells in the brain become active whenever they are confronted with different images or the name of a specific person or the identity of an object. They are highly selective and do not ...

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 ...

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 ...
