The brain tunes out information from the outside world, such as the sound of speech, during REM sleep. During light sleep, the brain prioritizes meaningful speech, just as it does during a wakeful state. Researchers believe the mechanism enables the brain to protect the dreaming phase, which is essential for memory consolidation.
Dietary triglycerides directly alter signaling in the reward circuit to regulate behavior. The findings reveal a potential mechanism by which triglyceride-rich diets may lead to adaptions in dopamine signaling that underlie reward deficit and compulsive behaviors.
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.
Researchers have developed a molecule that regulates the circulation of copper in the brain. The molecule extracts copper trapped in amyloid plaques in mouse models of Alzheimer's disease. Administered orally, the molecule inhibits memory loss associated with Alzheimer's.
A new voice manipulation algorithm allows researchers to visualize the neural codes people use to judge others by the tone of their voices.
Researchers reveal bees are able to grasp complex numerical concepts, such as the value of zero.
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.
Study identifies key factors in peoples' voices that show when they are lying.
Researchers have identified how a mutation causes dysfunction in a protein, which inhibits neural activity and induces migraines.
Researchers reveal social activity and the activity of dopaminergic neurons contribute to individuality in mice.
Researchers have developed a comprehensive "toolbox" to establish that the mobility of receptors exists in intact brain tissue, and this mobility is critical for certain types of memory.
