We propose a model in which the strengths of inhibitory ... is modified as a function of the global activity of the postsynaptic neuron and by correlated activity of the pre- and postsynaptic ...

The human brain contains about 86 billion neurons. These cells fire electrical signals that help the brain store memories and ...

The ultimate effect of this synaptic modification is to make the postsynaptic neuron respond more quickly. To illustrate this latency reduction, we considered a model neuron receiving inputs that ...

Researchers have a new hypothesis for how brain cells called astrocytes might contribute to memory storage in the brain. Their model, known as dense associative memory, would help explain the brain's ...

the nerve ending of the transmitting (presynaptic) neuron, the synaptic cleft separating the transmitting and receiving neurons and the membrane of the receiving (postsynaptic) neuron. The ...

The transmission of the signal from the presynaptic to the postsynaptic neuron is mediated by proteins and their imbalance can lead to neuropsychiatric conditions such as severe depression ...

"We are now working on a similar protein composition model for a whole cell (neuron)," Rizzoli said. More information: A large-scale nanoscopy and biochemistry analysis of postsynaptic dendritic ...

Between impulses the transmitter molecules are rapidly removed from the synaptic cleft to prevent continuous stimulation of postsynaptic ... into the presynaptic neuron and restored inside a ...

Different types of memories stored in the same neuron of the marine snail Aplysia can be selectively erased, according to a new study. Different types of memories stored in the same neuron of the ...
