Dendrites — these thin filaments carry ... a synapse. Synapses can be electrical or chemical. In other words, the signal that is carried from the first nerve fiber (presynaptic neuron) to ...

If the signals make sense ... contact points of the neuron. "The exciting thing is that the signals that a cell receives from, say, ten simultaneously active synapses can be greater than the ...

In new work published in Neuron, Stevens and colleagues reveal the flip side: a "don't eat me" signal that prevents microglia from pruning useful connections away. The signal, a protein called ...

If the signals make sense ... contact points of the neuron. "The exciting thing is that the signals that a cell receives from, say, ten simultaneously active synapses can be greater than the ...

The neuron, when considered as a signal processing device, itsinputs are the frequency of pulses received at the synapses, and its output is the frequency of action potentials generated- in ...

The contact points of cells in the cerebral cortex form functional groups - The cerebral cortex resembles a vast switchboard. Countless lines carrying information about the environment, for example ...

1). At the synapse, electrical impulses arriving from the axon are converted into chemical signals. The information then flows in only one direction: one cell talks, the other listens. The number of ...

Scientists report evidence that individual neurons carry ... synapses on a single neuron in a living mammalian brain. Focusing on neurons involved in processing movement-related signals, they ...
