The scientists observe that increased inhibitory signals cause this transition. While excitatory and inhibitory signals shape the early developing brain, the inhibitory signals appear later than ...

Researchers at Stony Brook University used genetic manipulation in a laboratory brain model to demonstrate that neurosteroids ...

Some of these signals are excitatory, meaning they increase the activity of the neurons that receive the signal. Other signals are inhibitory, meaning they decrease the activity of the neurons that ...

Excitatory synapses send signals that encourage the creation of an action potential by the next neuron; inhibitory synapses work against it. Each neuron receives signals from both excitatory and ...

Neurons come in two main “flavors,” excitatory and inhibitory. When an excitatory neuron receives enough input from other excitatory neurons, it fires, passing that signal along its axon to partners ...

However, a series of weak stimuli can combine, increasing the amount of neurotransmitter that is released. This results in enough neurotransmitter being diffused across the synaptic cleft to ...

Alcohol suppresses excitatory signals while enhancing gamma-aminobutyric acid (GABA), the main inhibitory neurotransmitter in the brain. When GABA receptors are stimulated, they reduce neuron firing, ...

Arianna Maffei in her lab viewing a slice of brain that shows the mark of the infusion in the gustatory cortex (identified by ...

Backpropagating action potentials and dendritic spikes are important signals for the induction ... Domain-specific properties in excitatory and inhibitory synaptic inputs, voltage-gated channels ...

New research suggests that Alzheimer’s disease damages the brain in two separate phases, with the first phase happening ...
