Research reveals atrophy of the amygdala and hippocampus at age 40 in patients later diagnosed with Alzheimer's disease.
A new study reveals people are able to recognize images they have only seen for a few seconds up to 10 years after exposure.
Study reveals receptor movement is essential for synaptic plasticity as a response to neural activity. Halting receptor movement may block specific memory acquisition, researchers report, thus confirming the role of synaptic plasticity in learning and memory.
Following a meal, astrocytes associated with POMC neurons in the hypothalamus alter their shape. After eating, glucose levels increase temporarily. Astrocytes detect the signal and react within one hour, causing POMC neurons to activate and promote the feeling of satiety.
