Acting as natural computers, our brains contain trillions of cells to store memory and control the body’s functions and emotions. Around one in ten of the countless cells in the … Continue Reading Microglia filmed shaping synapses for the first time.
Pain hypersensitivity can spread to unaffected body regions immediately surrounding the initial insult. Sometimes it can even spread to the opposite site of the body or to large body areas … Continue Reading Pain-initiating function of glial cells identified for the first time.
In alcoholism and addictive drugs repeated exposure triggers glutamatergic and GABAergic plasticity in many neuronal populations. The dorsomedial striatum (DMS), a brain region critically involved in addiction, contains medium spiny … Continue Reading Researchers identify and successfully activate neurons that tell the brain to stop drinking.
NMDA glutamate receptors function as receptors which bond with glutamates, and are known to be deeply involved in memory and learning. In order for memories to be created inside the … Continue Reading Study identifies microtubule protein crucial for synaptic plasticity and memory.
Memories are formed at structures in the brain known as dendritic spines which communicate with other brain cells via synapses. It is known that the number of these brain connections … Continue Reading Study identifies cause of dendritic pruning defect linked to autism and schizophrenia.
Whenever a person learns something new or is affected by their experiences it’s because synapses, the connections between neurons in the brain, have changed. Sometimes new synapses are made, and … Continue Reading Study shows how astrocytes help control synapse strength and plasticity.
It is known that the neurons of the human brain communicate with each other through specialized structures called synapses. A synapse consists of a presynaptic terminal of one neuron … Continue Reading Previously unknown molecule critical to synaptic transmission identified.
Alzheimer’s disease is the most common form of dementia, affecting over 44 million people worldwide. Inside the brain, Alzheimer’s disease is characterized by loss of neurons, and presence of abnormal … Continue Reading Protein involved in Alzheimer’s proven to have a role in weakening synaptic plasticity.
People who carry a variant of a gene that is associated with longevity also have larger volumes in a front part of the brain involved in planning and decision-making, according … Continue Reading Brain region vulnerable to aging is larger in those with longevity gene variant.
